Few infielders in the minors have Jazz’s bat speed, and even fewer have his swagger and flare. Though his high-effort hacks detract from his ability to make contact, Chisholm has shocking power for someone his size. When he really cuts it loose (which is often), he rotates with a violence and explosion reminiscent of Javier Baez and, like Baez, Chisholm is a high-risk prospect whose all-or-nothing style of hitting might ultimately be his undoing.

He has a one-note approach that mostly consists of him trying to ambush first-pitch fastballs. He’ll take some ugly swings when he’s cheating on a heater and instead gets something offspeed, though he has the bat control to put these balls in play if they’re near the zone. His strikeout rate (29% for his career) in undoubtedly a red flag, but because Chisholm is such a clean fit at shortstop (plus range, actions, and arm), he has some wiggle room on the offensive side, and shortstops with this kind of pop don’t exactly grow on trees. There’s star ceiling here, but also volcanic instability.

The list of catchers with speed comparable to Varsho’s is pretty short. J.T. Realmuto and Jorge Alfaro are two current examples, but Varsho reaches a top speed faster than either of them, and is an actual threat to steal bases. He’s also a doubles machine with natural feel for gap-to-gap contact, and if soft liners trickle between outfielders, Varsho can turn those into hustle doubles.

He remains a below-average receiver and often has trouble firmly squeezing balls in his glove, at times struggling to block breaking stuff in the dirt. Because Varsho is an above-average athlete, most scouts think these aspects of catching will become viable in time and that Varsho may just be behind in this regard due to his cold weather, small school background. His fringe arm strength plays up on scouts’ stopwatches because he’s very quick out of his crouch, so Dbacks games won’t turn into track meets with him behind the plate. He has a good chance to be an offensive-minded, everyday catcher.

Duplantier had been injury free since college (when he dealt with shoulder problems), until 2018, when he had hamstring issues in the spring, and biceps tendinitis later in the summer. The lost innings resulted in an Arizona Fall League stint, during which Duplantier was arguably the best non-Whitley pitching prospect who was a lock to start. Despite the biceps issue, his velocity was fine in the fall. Duplantier sits 93-96 and makes heavy use of three good secondary pitches. The horizontal action on his slider only plays away from righties, but the curveball and changeup will help mitigate some of those issues, as well as the platoon issues that may arise from Duplantier’s lower arm slot.

He doesn’t throw especially hard but the baseball appears to explode out of Widener’s hand, and it often gets on hitters much quicker than they’re expecting. Acquired in that massive, three-team, Steven Souza deal, Widener is a curvaceous 6-foot righty with several above-average pitches and average command. Much of the industry thought he was a reliever coming out of college, but the Yankees and Dbacks bought in on Widener as a starter, and they appear to have been correct.

The 2018 extended spring rehab group at Salt River Fields often included Jake Lamb and Steven Souza. Robinson, still 17 at the time, was just as big as both of them and about as fast as Souza, who is a 60 runner underway. Robinson is a Bahamian man-child, built like an SEC wide receiver and about as fast once he really gets going. He performed fairly well in his first pro season and was pushed to the Pioneer League late in the summer.

He has some swing and miss issues, and his bat path needs some work to get to all the power that’s coming, but the foundation for a combination of contact and power is present. It’s unlikely that Robinson stays in center field forever, and he may even need to move to right while he’s still in the minors, but the power that comes with all that good weight could approach the top of the scale. He’s a high risk, high upside teenage power-hitting prospect.

Perdomo is among the most advanced switch-hitting teenagers on the planet, possessing innate feel for contact from both sides of the plate despite what can sometimes be an awkward-looking swing. As of list publication, he has a plus-plus walk rate over about 150 pro plate appearances, enough to be confident that he has value-adding feel for the strike zone. Not only that, but he is a potential 55 or 60 glove at short. Already procedurally advanced, Perdomo will likely get quicker and more explosive as his body matures, but his frame is not so large that he projects to third base; he’s a high-probability middle infielder.

The quality of Perdomo’s contact may eventually result in power output beyond his raw grade; he’ll be a star if that happens. If not, a defensive asset at short with a plus bat and excellent ball/strike recognition is still an everyday player.

Pre-draft questions about Thomas focused on his physicality, or lack thereof, despite his long track record of hitting against elite competition at amateur showcase events around the country. He’s well-conditioned, but short, built narrowly, and likely to max out with a frame similar to Brett Gardner’s. And Thomas projects to have a similar skillset. It’s rare that a high school hitter from Chicago is this polished, especially one as young as Thomas, who was barely 18 on draft day.

He runs well enough to project in center field (though his reads from the corners are much better right now and he might just be a plus corner glove, also like Gardner), which makes the unenthusiastic, frame-based power projection less concerning. There’s some tweener fourth outfielder risk here because of the lack of power projection and potential move off of center field, but it’s reasonable to hope some combination of contact, on base ability, and defense make up for that and enable Thomas to be a regular.

Signed for $1.85 million last July, Guzman has yet to set foot on a baseball field in the U.S., but he’s already one of the most exciting players in this system. He has a rare combination of speed, frame, and swing foundation, a triumvirate that gives Guzman a chance to be a five-tool star, something most prospects simply don’t have a chance to become.

He has a loose, whippy swing that he doesn’t always control, and had among the best straightline speed in the 2018 July 2 class. The footspeed makes Guzman a rangy outfield defender and likely to stay in center. His hands have enough life in the box that he might do offensive damage, too. We have no data on important aspects of Guzman’s ultimate profile, making him as risky a prospect as he is skilled. He may not come stateside until this fall for instructional league, unless he so convincingly dominates the DSL that Arizona is compelled to promote him.

Teams with Extended Spring coverage in Arizona were split as to which of the two Dbacks shortstop prospects they preferred until Geraldo Perdomo separated himself with his summer performance. Some teams were early Peguero advocates, citing his age, superior athleticism, and a build comparable to a young Jean Segura’s.

Like most of Arizona’s teenage shortstop prospects, Peguero earned a late-summer promotion with early-season performance, slashing .309/.356/.457 in the DSL. His swing is shorter than a mid-inning station identification and he takes good at-bats for someone his age, so there’s big ceiling on the hit tool if his timing at the plate improves. He’s also a rangy defender with a plus arm and at least average hands. He can go into the hole, backhand a ball, plant, and hose runners. The frame isn’t favorable for power projection, but Peguero’s hands are so quick that he might be able to pull and lift enough balls to actually produce some homers. His swing is not currently geared for that type of contact, though. Regardless, the bat and defensive ability is promising, as is the frame and athletic ability. He has everyday shortstop upside.

Tabor’s velocity seems to have plateaued after it exploded as his wiry frame filled out later in high school. He’s sitting in the low-90s, with a breaking ball and changeup that each flash above average. He’s athletic, his arm slot creates rise on his fastball and bat-missing, vertical action on his breaking stuff, and Tabor has unusually good feel for his changeup, especially for a northeast prep arm. It looks like he’s going to move along developmentally with the advanced teenagers from last year’s rookie-ball group. He’s the best long-term pitching prospect in this system, and has a chance to be a No. 4 starter if the velo finds another gear, more likely a No. 4/5 if it does not.

Alexander fell out of the top 10 rounds of last year’s draft due to questions about his signability, hit tool, and age relative to his peers. He was almost 19 on draft day, which, combined with the strikeout issues, moved him way down the boards of teams who care about those variables, especially together. He ended up signing for a very reasonable $500,000, then hit .362 against AZL pitching and was eventually promoted to the Pioneer League.

He’s an advanced defender with an 80 arm (the teams most bearish on his bat in high school wanted to see him on the mound) and above-average raw power, which Alexander’s pre-daft proponents insisted he’d get to despite the strikeouts. We don’t know much about the plate discipline aspect of the profile yet. The low end of the spectrum makes the offensive skillset read like Tim Beckham’s, but Alexander projects as a better defender.

McCarthy’s older brother Joe was a hyped prospect who slid on draft day due to a down spring stemming from a back issue. Jake also missed most of his draft spring, but with a broken wrist. He returned not long before the draft and did not look very good, and teams had mixed opinions about him on draft day. Some thought he just needed more time to get back to full strength and speed, while others were scared off by their post-injury looks, which were so bad that multiple scouts told us they thought he may have been better off sitting out rather than giving teams a bad look just before the draft.

At his best, McCarthy shows at least average raw power, plus speed, some feel to hit, and is a center field fit. His swing is naturally geared for opposite field contact, which will likely cap his power output unless he undergoes a swing change. That will be less necessary if McCarthy stays in center field. Season-long failure to hit in the Cal League will leave us with more questions about McCarthy than we had entering the year, especially if his early-season struggles with strikeouts persist.

There are lots of different ways to frame arguments about Leyba. On the one hand, he’s a switch-hitting middle infielder who has made lots of contact — Leyba is a .285 career hitter — over six pro seasons. On the other, he has been hurt a lot — shoulder surgery, most recently — and may be painted into too small a defensive corner to be rosterable if he doesn’t hit enough to be a regular. It’s important to be mindful of prospect fatigue creeping in here, as Leyba really broke out during the summer of 2014 when as a teenager, he hit a combined .323 in the Penn and Midwest Leagues. He was sent to Arizona as part of the three-way, Didi Gregorius-headlined trade that offseason, had a bad 2015 in the Cal League, bounced back in 2016, and has basically been hurt since.

Because of Leyba’s size and lack of power, he has to keep making high-end rates of contact to profile as an everyday player. If he lacks sufficient arm strength for shortstop coming out of the shoulder surgery, it puts even more pressure on the hit tool, because a bench role is less feasible for someone without defensive versatility.

Middle infielders with power are rare and yet Young, who is exactly that, somehow lasted until the 37th round of his draft and signed for just $3,000. This is the Cardinals’ archetypical draftee — a power-first prospect with questionable mobility. Collect enough of these and, through a combination of luck and good player development, some of them will turn into passable defenders and become solid big leaguers or tradable assets like Young, who was sent to Arizona in the Paul Goldschmidt deal.

Though he does most of his damage on pitches on the inner half, Young has enough barrel control to spoil pitches away from him until he gets something he can square up. When Young connects, he does so with power. Buff and square-shouldered, Young’s physicality is a driving component of his power but it’s also why he’s somewhat limited defensively. Young has seen time at shortstop, third base, and left field as a pro but was mostly kept at second base in 2018. He should be a passable defender there, but his lack of defensive versatility could be a barrier to a call-up unless he hits enough to be an everyday player. He’s a realistic internal candidate to play the kind of role Wilmer Flores is currently playing on Arizona’s active roster.

Toolsy and physical, Patino has an exciting combination of speed and power, as well as promising ball/strike recognition. What he appears to lack at this point is barrel control and a bat path that enables the power. Those are important components and may not be easy to fix, especially the bat control issue. But Patino’s ball/strike and breaking ball recognition could help mitigate those issues, and his ceiling (a high OBP center fielder with power) is lofty if they’re overcome. A max-effort player with a fairly mature build, Patino seems poised to have a strong statistical summer against AZL pitching and defenses, perhaps enough that he’ll see some Northwest League time late in the year.

At times, Frias looks like a stiff, velo-only bullpen prospect. At others, he’s competing in or near the zone with four pitches, including a splitter that got much better over the winter. All four pitches give hitters a vastly different look. Frias’ mid-90s fastball has tailing action, his curveball has vertical depth and eats up hitters who are cheating on velo, the split has late bottom when it’s on, and the slider has horizontal, cutting action. The movement profile of Frias’ fastball may not be the best for missing bats, but it’s likely to be an impact pitch because of the velocity. He could end up with three average secondaries (there’s a chance the split becomes better than that) and enough strikes to start, making him a potential No. 4/5 starter.

Green was a 14th round senior sign last year and like most senior signs, had 45/50 stuff in college. He was 90-94 with two average breaking balls and had little college experience because he didn’t move into the rotation until his senior season.

This spring, however, Green’s stuff was up. He was 92-95, touching 96, and flashing plus secondary stuff including a good changeup. The Dbacks may have found something here, though there’s no way to be sure if the velo uptick will hold water or not. He has No. 4 starter stuff if it does, and some scouts with Dbacks coverage this spring prefered Green to several more high-profile arms in the system. He’s currently on the IL with biceps tendinitis.

Clarke has a four-pitch mix that plays in part because of big extension. He has feel for locating his cutter (glove side) and change (arm side) better than he does for his other pitches, but his fastball sneaks up on hitters because of the extension, so Clarke has command margin for error in the strike zone. He’s a low-variance fifth starter prospect who should see significant big league time this season.

Lopez seems to have moved past a tumultuous first few chapters of his Dbacks tenure and settled into a seventh and eighth inning role. He blows upper-90s heat past hitters at the top of the zone and above it, and he generates flaccid swings at his slider when working away from righties. Once developed as a starter, the return of a third pitch might enable Lopez to be an elite reliever down the line, if he doesn’t already have high-leverage stuff. He’s under team control until 2025 and has unusually high trade value for a single-inning reliever, especially for teams unconcerned about his early issues.

Ellis has a very quiet, easy swing but somehow still generates plus power. He has middling pitch recognition, which sometimes causes him to mistime pitches. This manifests as lots of awkward or checked swings, but he doesn’t typically flail and whiff, and Ellis is strong enough that the contact has a chance to be meaningful even if he didn’t take a great cut. It’s a fair, power-over-hit corner profile that takes a hit if Ellis should ever need to move to first base. So far he’s been playable, but not impactful, at third.

Smith struck out just 12 times as a college junior and had 25 more walks than strikeouts during his entire UVA tenure. Pre-draft questions about his ability to hit for power in games have proven to be pertinent. But Smith hits and he walks, so a relevant swing change, even one that sacrifices some contact, could lead to a breakout here. After some early-season statistical indicators that one might be occurring, Smith’s groundball rate has regressed to the mean. He’s a speculative low-end regular at first base.

After a strong 2017, Diaz spent 2018 injured (twice) and unproductive. His physical tools remain the same; Diaz runs and throws well, and has above-average bat speed and power. While some of his 2018 swoon was a result of injury and the offensive environment in the Midwest League, some of his issues were also swing-related. He has to take big, long, full-armed hacks to generate that bat speed, and so he lacks elegant feel for the barrel. He’s playing both outfield corners now, not center. It makes the hit tool problems more of a concern, but ultimately, this is a college-aged hitter with tools that come off the board fairly early on day two.

Vargas’ delivery has a cadence that hitters seem able to time, but it’s graceful, athletic, and repeatable. He has burgeoning control of No. 4/5 starter stuff, led by a two-plane breaking ball that Vargas can locate in the zone and beneath consistently. He’s well built, throws pretty hard, and has performed up through Double-A, and he’s now on the 40-man. There’s a chance he sees his first big league time this season.

Ginkel’s velocity has exploded since college, and he now sits 93-96 with tough angle. He also has two good secondaries, a change and slider that both have late, downward movement. He’s a likely long-term bullpen piece.

Alvarez signed for $65,000 in 2017. Newly 18 and still fairly projectable, Alvarez has already touched 95 and is flashing a plus split. He has below-average breaking ball spin but sometimes creates good shape and depth on it. He’ll be measured against recently-drafted high school arms in this year’s AZL, and there are some pitchability and breaking ball questions that need answering, but the velo and splitter are promising.

Mercer was a max-effort 94-97 in college, had scattershot fastball command, and a plus changeup. His velo is down and neither of his two breaking balls has great movement. We think he’s a Tyler Clippard-style changeup reliever so long as the velocity returns.

Goddard was worked hard at Kansas, sometimes throwing around 120 pitches several starts in a row, and his velocity was down after last year’s draft. He’s a big-framed guy with average stuff that plays up due to extension and his fastball has life that competes in the strike zone. Realistically he’s a fifth or sixth starter but let’s see how the fastball plays and what happens to the velocity when Goddard is handled in a way that prioritizes development rather than winning Big 12 games.

Barrosa isn’t toolsy but he has good feel to hit from both sides of the plate and terrific defensive instincts in center field. He’s stout and not very projectable, but already looks like a potential bench out field type who can play all three spots and let you match up late in games.

Peacock has a heavy, mid-90s sinker that has enabled him to generate a 78% groundball rate this year. His slider has a 2800 rpm spin rate but visual evaluations of that pitch put it closer to average. His changeup moves and tails, but is often easy to identify out of his hand due to altered release/arm speed. On some level, Peacock is a one-pitch 25-year-old, but on another he has a dominant, grounder-inducing fastball and his secondaries have some characteristics that may just need to be refined for one or both of them to be effective.

Weiss is a four-pitch (maybe five — there may be both a slider and cutter) strike-thrower whose overhand, trebuchet delivery creates vertical action on most of his stuff. He may be a backend starter.

Holton blew out his elbow in his first 2018 start at Florida State and needed Tommy John. He was only throwing 87-90 before the injury but both his changeup and breaking ball were flashing plus. So long as his stuff comes back after surgery, he’ll probably carve the lower minors. There are some instances of velocity upticks coming out of Tommy John (Walker Buehler is a prominent recent example) and if Holton has one, he’ll rocket up this list.

Lewis got $125,000 in the 2018 12th round. He’s very tall, long, and is athletic for his size, and he has great changeup feel. He has below-average fastball velocity, but it plays up a few ticks because of extension, and Lewis doesn’t often make crushable mistakes. His slider is okay when it’s located, but the changeup is Lewis’ best swing and miss option against hitters of either handedness. He has sixth starter stuff on the surface, but there’s a chance that 6 or better command develops late (Lewis is already 23) because of Lewis’ size. If that happens, he’ll pitch in the back of a rotation.

Bart was a solid mid-tier prep prospect in the Atlanta suburbs who a couple of clubs really liked, but they ultimately couldn’t meet his price, pushing him to Georgia Tech. He made the leap between his sophomore and junior years, growing into his athleticism and developing plus raw power along with above average defensive tools and arm strength. The defensive tools are especially rare for a catcher of Bart’s size, as it’s much easier for a more compact-framed player to excel behind the plate. Bart has the rare ability to slow the game down defensively and scouts rave about his makeup, game calling, and game preparation.

At the plate, Bart has big power and gets to it pretty often in games, particularly to his pull side, where he hit a majestic shot that was never found over the facade of the football complex in left field at Georgia Tech’s stadium. But while he is exceptional behind the plate, Bart doesn’t have the same ability to slow the game at it, with elevated strikeout rates in his draft year and just okay pitch selection. The bat speed is good and he doesn’t have trouble against velocity, and some scouts point to his solid pro debut as evidence that Bart was just frustrated by being pitched around and developed some bad habits in college. Since literally everything else you could want except for contact is already present, most assume that Bart will figure out a way to get to a 40 to 50 bat with above average game power and above average defense, even if it’s on the job in the big leagues in 2020. He broke his hand early in 2019 and will miss several weeks. He’s a strong Arizona Fall League possibility.

After he looked like a newly-drafted force of nature during the summer of 2017, Ramos’ physical tools actually regressed last year. The bat speed and quality of contact both dipped, and Ramos was noticeably out-shined by the other (mostly older) Futures Game participants during batting practice. Ramos developed some feel for opposite field contact during this span, something he retained as the power returned this spring. He’s hitting lasers to all fields now, adept at peppering the right center field gap.

Built like, and as fast as, a bowling ball SEC running back, Ramos is going to stay in center field for a while but most scouts think he’ll eventually move to a corner. That could be a problem if such a move occurs sooner than anticipated, as Ramos has had whiff/discipline issues in the past, though they’ve been much more palatable this year. He has Mitch Haniger/Randal Grichuk-ish tools. Staying in center will be important, as will retaining some of this new plate discipline. If both happen, Ramos is going to be a highly entertaining star.

Luciano’s broad, square, muscular shoulders look like they belong to a D1 high school football prospect. He has one of the better frames of all the 17-year-old hitters in pro ball, and plenty of room to add power to a body that already produces a lot of it. Luciano has explosive hands and a natural uppercut swing. He hits many more balls out during BP than is typical for a hitter this age, and has taken his peers deep in games, too.

Luciano’s feet and actions are workable on the infield but he struggles with throwing velocity and accuracy when he’s forced to throw from a lower arm slot, as shortstops often are. If he can’t correct that, he’ll need to move to the outfield. If he can, this is a shortstop with 80 bat speed. Luciano is a potential superstar. Much of his profile (the plate discipline, ultimate defensive home) is still not in focus, but this young man has rare physical talent.

This system has three teenagers with awesome bat speed, and Canario is one. Some of his batting practice sessions during the Giants’ new January instructional camp were even up there with Joey Bart’s. But much of Canario’s game is unkempt. He has mediocre natural timing and feel to hit, and his front side often leaks, which impacts his ability to spoil breaking stuff away from him. His lower half got thicker and stronger during the offseason, making it more likely that he ends up in right field rather than center. But this is a potential middle-of-the-order hitter because of the raw power; the swing has natural loft, and the early-career plate discipline data is strong. There’s huge ceiling if the hit/approach component improves, but of course, this type of prospect often fails to fully actualize.

The Giants proactively sent Santos, who was acquired from Boston as part of the Eduardo Nunez deal, to the Northwest League as an 18-year-old because his stuff was simply too powerful for AZL youngsters. He was 93-96 with sinker and cutter variation last year, and his breaking ball was often plus. He threw more strikes in affiliated ball than he did during the spring in extended, then arrived to 2019 camp with a better changeup. A strong breakout candidate, Santos had a shoulder strain in late-April. There’s probably no more velo coming because Santos is a mature-bodied guy, but he already throws hard so that doesn’t really matter. He has mid-rotation upside as long as the command improvement holds and this shoulder issue doesn’t become chronic.

Hjelle body comps to a young Pau Gasol and is remarkably athletic for his size. His delivery is graceful and fluid, and he has no trouble repeating it nor fielding his position, as he’s quick off the mound to corral bunts and cover first base, both of which can be challenging for XXL pitchers. Hjelle’s (it’s pronounced like peanut butter and _____ ) fastball only sits in the low-90s but plays up because of extension, life, and the angle created by his height. Those traits in concert with one another make for a heater that competes for whiffs in the zone. The secondaries are closer to average, often below, though Hjelle can locate them. He’s a pretty safe No. 4/5 starter candidate, though we might be underrating the impact of Hjelle’s size on hitters’ discomfort.

A raw, arm strength goon for what seemed like forever, Adon found slider feel late last season and had dominant stretches where he looked like a potential closer. He has carried that into the early part of this season, more frequently dotting his slider just off the plate to his glove side and even getting it over for strikes when he’s behind in counts. Adon still just kind of chucks his fastball and hopes it arrives near the plate, but he’s going to get away with mistakes in the zone because of the velocity. Likely to have harrowing bouts of wildness, Adon has high-leverage/closer stuff and could be one of the better relief pitchers in baseball at some point, though he may already be in his late-20s once things really click.

Anderson has an unusually deep repertoire for a pitcher who scouts overwhelmingly project into the bullpen. He has a two seamer, a four seamer that has natural cut to it when he locates to his glove side, a slider (his best pitch dating back to college), and a changeup which has been the focal point of development since Anderson entered pro ball. A casualty of Florida’s ability to recruit and develop pitching, Anderson was a college reliever who would’ve been starting on just about every other college team in the country, so there’s a reason he lacks some of the finer attributes scout want to see from a starter. He could be an inefficient No. 4/5, but he might be really good in a multi-inning relief role where he throws 80 or more innings.

Webb spent most of 2016 on the shelf due to Tommy John, and the little bit of 2017 for which he was healthy he spent in a well-manicured relief role. Then he broke out in 2018, as he retained big stuff through a move back to the rotation. He was holding a tailing 92-95 deep into starts, topping out at 97, and spinning in a dastardly, bat-missing breaking ball. Unrefined fastball control led to a lot of bullpen projection, but Webb hadn’t pitched very much because of injury, so it seemed possible that it might yet improve.

Early in 2019, Webb’s stuff was down a bit, more 91-94 and touching 95, before he got popped for PEDs and was suspended for 80 games. He’s missed about two years of development due to the TJ and this suspension and developmentally is more like a junior college arm than an advanced Double-A prospect. He has Top 100 stuff (assuming the 2018 heater comes back after this suspension) and if he can somehow refine fastball command and the changeup (or a third pitch of some kind), he could be a No. 4 starter. We don’t know how the PEDs, which Webb denies knowledge of using, may have impacted his stuff. He seems like a logical Fall League candidate.

Of all the players we’ve written up on the team reports (there are about 1,000 on The Board and well over that if you count the Others of Note section of the lists) the gap between what Hilson is now and what he might be is perhaps the biggest. He has scintillating physical ability. Speed, arm strength, barrel quickness, burgeoning power, hit-thieving defensive ability in center field. But he is raw as steak tartare and often takes hapless, juvenile swings that demonstrate an alarming lack of baseball feel, as evidenced by his 67 strikeouts in 166 2018 at-bats.

Likely a long term project who will move through the minors with this exciting young contingent of talent from Latin America, Hilson’s chances of even making the big leagues are probably in the 20-30% range, and that may be optimistic. But on the scouting card, the tools read like David Dahl’s or Starling Marte’s, so there’s a chance for a star turn here, as well. It will likely take a long time and there will likely be developmental bumps in the road, but Hilson has monster, long-term potential and would be a peacock feather in the cap of Giants player dev if he can realize it.

This is one of the weirder pitchers in all of the minors. At times, Doval will sit in the upper-90s with cutting action; at others, he’s living in the low-90s with no movement. Scouts think the cause is that he doesn’t grip the baseball in a consistent manner. Doval also has a delivery totally unique to him. It’s a long, swooping, side-winding look that creates cut/rise on the ball. He also throws a hard, horizontal slider.

The Trackman readout for Doval is shocking. His primary fastball/cutter spins in at about 2700 rpm, which is incredible considering how hard he throws. He also generates nearly seven feet of extension, and the effective velocity of his fastball is about 2 mph harder than it’s actual velo.

He has outings where he walks everyone and gives up a bunch of runs before he accrues an out, and he has outings where he’s untouchable for several innings. It’d be somewhat terrifying to acquire Doval if the outcome of a trade for him dictated one’s job security, but his stuff is bewitching and we think he has a chance to be an elite bullpen weapon if he ever figures things out.

Corry was a pretty raw fastball/curveball high school prospect whose changeup got much better throughout last season, which is especially relevant because that pitch’s movement pairs better with his fastball than the curve does. He’s a fairly stiff, short strider and often has scattershot fastball control, so there’s significant relief risk here. But Corry’s pitch mix is more complete than most of the other arms in this system and he’s the youngest non-Santos arm on the main section of this list, so you could argue he belongs up near Hjelle if you think he ends up starting. Realistically he’s a No. 4/5 or a three-pitch relief piece.

It appears that Beede has ditched the cutter/slider thing bestowed upon him for a time and is, as he was in college, a fastball/curveball/changeup guy again. His velocity also seems to have been reborn. He’s once again lighting up radar guns with a mid-90s heater that has touched 98. His changeup has power sinking movement and should miss bats when Beede locates it competitively, but he’s more consistently able to do that with his curveball. Fastball control likely keeps Beede in the bullpen even though he did have stretches this spring where he looked like a mid-rotation starter. He’s 26, but looks like a strong three-pitch reliever. Maybe there’s a chance for high-leverage or multi-inning work here.

Built at age 18 like Aramis Ramirez was in his prime, it’s likely that Toribio’s promising pro debut was at least somewhat a product of physical maturity. He has above-average raw power already and generates it with a comfortable, understated swing. He’s shown feel for contact in games. He’s too pull-heavy at times, or at least tries to pull pitches he shouldn’t, ones he should just take. So there’s power, early indicators that the contact skills will be fine, and a chance to stay at third. The size/frame means there’s risk Toribio ends up at first base if he gets bigger, and also probably means we shouldn’t expect much of an increase in raw power. He has a chance to be an everyday third baseman, and lots of other viable outs if he can’t get there, including a corner infield platoon of some kind and a low-end first baseman. Or maybe more power comes, and he’s a 50 at first.

Boxed out of a surprisingly crowded corner outfield situation in Detroit, Gerber should get an opportunity to become a lefty-hitting platoon corner outfielder with power. He has at least above-average raw and has adjusted his swing to better ensure consistent lift. He’s going to strike out a lot, but he mashes right-handed pitching and plays a very good corner outfield, so he might play against lefties, too, and just hit toward the bottom of the order on those days. He’s older, but is a clear fit in a limited but necessary role.

The Giants signed Pomares for just shy of $1 million during the 2018 July 2 period. He’s already almost 19 and is, as one can probably guess, a little more advanced and a little less projectable than most other recent J2 signees. Pomares is a center field prospect with feel to hit. His swing is geared for all-fields contact and while he has above-average bat speed, it’s unlikely that he hits for power without a swing adjustment. He looked a little thicker and stronger than anticipated during San Francisco’s January instructs and early in the spring, so there may be less certainty that he stays in center than there was when Pomares was in Cuba. He looks more like a fourth outfield prospect than a potential regular right now, but Cuban players often have long stretches away from baseball and training, so what we’ve seen so far in Arizona might just be rust.

Black is the oldest player on The Board and he’s only here, despite a career rife with injury and inconsistency, because his stuff is so good. He’s among the hardest throwers in professional baseball and also one of the best at spinning the baseball. He is wild and the quality of his secondary stuff is inconsistent, but at times he looks unhittable. He struck out 33 in 23 big league innings last year, but he’s currently on the IL with a forearm strain. He could one day pitch his way into high-leverage innings as long as he has this kind of stuff, which he has maintained despite the many maladies.

Built like a one of the moai sculptures on Easter Island, Genoves faces size-based questions about his ability to catch long term. But he has a plus arm, he’s procedurally advanced for a 20-year-old, and he has the leadership qualities and intangibles that have an outsized impact at catcher. He also has plus power, enough to put balls out to right center, though Genoves’ current approach to contact doesn’t often enable it. He pulls just about everything.

Genoves’ future is heavily dependent on him staying behind the plate and ideally, he’d catch more than just 33 games (last year’s total at an affiliate, not including extended) throughout the course of this year, and show that the workload doesn’t detract from his bat or agility. The power gives him a shot to be a regular, though a backup role is probably more likely.

The Giants drafted Rivera after his 2017 freshman season, but he went back to school, raised his stock, and was the first JUCO arm off the board the following year. He has power stuff — 93-96 with cut action at times, and a plus curveball — but is wild and may be a reliever, though probably a very good one.

Wong was holding 93-96 with sink deep into games as a junior, he throws strikes, and he occasionally snaps off a good curveball. Changeup development and refined command are areas of need, and they will likely dictate Wong’s ceiling, which is probably that of a No. 4/5 starter who induces weak contact rather than strikeouts.

Shaw is one of many whiff-heavy corner bats with huge power who floats around the upper levels of the minors, putting up big power numbers while struggling to find a big league role if their parent club has someone at 1B/DH. The Giants have tried Shaw in the outfield but scouts don’t think he’s playable out there. Shaw has the advantage of hitting left-handed, but unless the Giants make a concerted effort to give him reps soon (they demoted him to Double-A to start 2019, so not a great sign) he’ll probably bounce around on waivers until a team with 40-man space — and the time to see whether or not Shaw can hit big league pitching — gives him a chance. Sometimes this is how clubs fall into Jesus Aguilar and Christian Walker, but it’s also the fate of many a Quad-A hitter.

Miller’s lack of arm strength really boxes him in at second base, which means he has to hit enough to be a regular there because defensive versatility, and therefore a viable utility role, isn’t part of his profile. Much of the pressure will be on the bat to ball skills as Miller is a compact guy with average bat speed. He probably needs to be a 60 bat or better to play every day, which is feasible considering that his attributes, dating back to high school, are lead by a short swing and barrel control. He’s off to a good start in 2019, walking nearly as much as he has struck out.

Though he looked somewhat better defensively during January workouts, Gonzalez still projects over to first base for all the scouts we’ve spoken with, and his inability to hit breaking stuff makes that pretty scary. He’s a hard worker with a frame built for longevity and he has arguably the best raw power in this system. His future looks much like Shaw’s, but Jacob hasn’t had the in-game power output yet.

Last year, Avelino shuttled back and forth between Double-A (which he crushed) and Triple-A (which he did not) while with the Yankees, then was sent to San Francisco at the end of August as part of the McCutchen trade. He has rare power for a viable defensive shortstop but hits the ball on the ground so much that it’s highly unlikely he does much in-game damage with the bat unless his swing is overhauled. And while solid at short, Avelino’s not so good that you’d live with zero offense and play him everyday. He’ll likely be a glove-first utility guy, but he hasn’t played much second or third base yet and he’s already 24.

Former MVP George Bell has two sons also named George Bell in pro ball — this one and George Bryner Bell, who is with Oakland. This Bell is a body/power/speed junior college sleeper who has some plate discipline and bat control issues. He has a shot to break out in the Northwest League this summer and merit a promotion to Low-A for the stretch run. August will be a key time to evaluate him if that’s the case.

We typically slot relievers in their mid or late-20s in the honorable mention section of lists, especially if they’ve had injury issues. But the four you’re about to read about all have premium stuff and, at least at times, look capable of handling late-inning duty. Arm injuries have limited Gustave to 20 total innings since 2016, but his fastball was back into the upper-90s this spring. His slider is closer to average right now, which may mean he maxes out in a lower-leverage role.

Vizcaino has been hurt for long stretches during the last few years and was moved to the bullpen this spring. He’ll touch 98 but sit mostly 91-95, and he has an above-average changeup, as well as two lesser breaking balls.

Wolff was part of the Matt Moore trade and he’s spent time in Double-A every year since 2016. He has standard 40 FV, middle relief stuff, but he’s 28 and has a long injury history.

Marte has a four-pitch mix and generates plus-plus extension, which makes his mid-90s fastball play up. We have his 2018 breaking ball spin rate on The Board because this year’s are way, way down, likely due to injury.
