55 FV Prospects

Drafted: 1st Round, 2018 from Georgia Tech (SFG)
Age 22.4 Height 6′ 3″ Weight 225 Bat / Thr R / R FV 55
Tool Grades (Present/Future)
Hit Raw Power Game Power Run Fielding Throw
30/45 60/65 45/55 40/30 55/60 55/55

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.

2. Heliot Ramos, CF
Drafted: 1st Round, 2017 from Leadership Christian HS (PR) (SFG)

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.

Hit Raw Power Game Power Run Fielding Throw
20/50 60/70 20/60 50/50 40/50 50/55

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.

45 FV Prospects

Hit Raw Power Game Power Run Fielding Throw
20/45 60/65 30/60 55/50 40/50 60/60

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.

Signed: July 2nd Period, 2015 from Dominican Republic (BOS)

Tool Grades (Present/Future)
Fastball Slider Changeup Command Sits/Tops
55/60 50/60 45/50 35/50 92-96 / 98

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.

40+ FV Prospects

6. Sean Hjelle, RHP
Drafted: 2nd Round, 2018 from Kentucky (SFG)
Age 22.0 Height 6′ 11″ Weight 215 Bat / Thr R / R FV 40+
Tool Grades (Present/Future)
Fastball Curveball Changeup Command Sits/Tops
50/55 45/50 45/50 45/55 91-94 / 96

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.

7. Melvin Adon, RHP
Signed: July 2nd Period, 2014 from Dominican Republic (SFG)
Age 24.9 Height 6′ 3″ Weight 235 Bat / Thr R / R FV 40+
Tool Grades (Present/Future)
Fastball Slider Changeup Command Sits/Tops
80/80 60/60 40/40 30/40 96-100 / 102

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.

Drafted: 3rd Round, 2016 from Florida (BOS)
Age 24.5 Height 6′ 4″ Weight 225 Bat / Thr R / R FV 40+
Tool Grades (Present/Future)
Fastball Slider Curveball Changeup Cutter Command Sits/Tops
55/60 55/60 50/50 45/50 55/55 40/45 91-95 / 96

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.

9. Logan Webb, RHP
Drafted: 4th Round, 2014 from Rocklin HS (CA) (SFG)
Age 22.5 Height 6′ 2″ Weight 220 Bat / Thr R / R FV 40+
Tool Grades (Present/Future)
Fastball Curveball Changeup Command Sits/Tops
55/60 55/60 45/50 40/45 91-94 / 95

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.

Drafted: 6th Round, 2018 from Nettleton HS (AR) (SFG)
Age 18.7 Height 5′ 11″ Weight 175 Bat / Thr R / R FV 40+
Tool Grades (Present/Future)
Hit Raw Power Game Power Run Fielding Throw
20/35 50/55 20/45 70/70 45/55 70/70

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.

11. Camilo Doval, RHP
Signed: July 2nd Period, 2015 from Dominican Republic (SFG)
Age 21.9 Height 6′ 2″ Weight 185 Bat / Thr R / R FV 40+
Tool Grades (Present/Future)
Fastball Slider Cutter Command Sits/Tops
55/60 45/50 60/70 20/40 89-98 / 100

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.

40 FV Prospects

12. Seth Corry, LHP
Drafted: 3rd Round, 2017 from Lone Peak HS (UT) (SFG)
Age 20.5 Height 6′ 2″ Weight 195 Bat / Thr L / L FV 40
Tool Grades (Present/Future)
Fastball Curveball Changeup Command Sits/Tops
50/55 50/55 50/55 40/45 90-94 / 95

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.

13. Tyler Beede, RHP
Drafted: 1st Round, 2015 from Vanderbilt (SFG)
Age 26.0 Height 6′ 2″ Weight 190 Bat / Thr R / R FV 40
Tool Grades (Present/Future)
Fastball Curveball Changeup Command Sits/Tops
60/60 50/50 55/55 40/40 91-95 / 98

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.

14. Luis Toribio, 3B
Signed: July 2nd Period, 2017 from Dominican Republic (SFG)
Age 18.6 Height 6′ 1″ Weight 210 Bat / Thr L / R FV 40
Tool Grades (Present/Future)
Hit Raw Power Game Power Run Fielding Throw
20/50 55/60 25/55 40/30 40/45 55/55

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.

15. Mike Gerber, RF
Drafted: 5th Round, 2014 from Creighton (DET)
Age 26.9 Height 6′ 0″ Weight 190 Bat / Thr L / R FV 40
Tool Grades (Present/Future)
Hit Raw Power Game Power Run Fielding Throw
40/40 60/60 50/55 50/50 55/55 50/50

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.

16. Jairo Pomares, CF
Signed: July 2nd Period, 2018 from Cuba (SFG)
Age 18.8 Height 6′ 1″ Weight 185 Bat / Thr L / R FV 40
Tool Grades (Present/Future)
Hit Raw Power Game Power Run Fielding Throw
25/55 45/45 20/35 55/50 45/50 45/45

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.

17. Ray Black, RHP
Drafted: 7th Round, 2011 from Pittsburgh (SFG)
Age 28.9 Height 6′ 5″ Weight 225 Bat / Thr R / R FV 40
Tool Grades (Present/Future)
Fastball Slider Command Sits/Tops
80/80 55/55 35/35 96-99 / 102

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.

Hit Raw Power Game Power Run Fielding Throw
30/50 55/60 30/45 20/20 45/50 50/50

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.

19. Blake Rivera, RHP
Drafted: 4th Round, 2018 from Wallace State CC (SFG)
Age 21.4 Height 6′ 5″ Weight 225 Bat / Thr R / R FV 40
Tool Grades (Present/Future)
Fastball Curveball Changeup Cutter Command Sits/Tops
55/55 55/60 40/45 55/55 40/45 93-97 / 98

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.

20. Jake Wong, RHP
Drafted: 3rd Round, 2018 from Grand Canyon (SFG)
Age 22.7 Height 6′ 1″ Weight 210 Bat / Thr R / R FV 40
Tool Grades (Present/Future)
Fastball Slider Changeup Command Sits/Tops
50/50 45/50 40/45 40/50 92-95 / 96

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.

21. Chris Shaw, 1B
Drafted: 1st Round, 2015 from Boston College (SFG)

Hit Raw Power Game Power Run Fielding Throw
45/50 50/55 70/70 40/40 40/40 55/55

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.

22. Jalen Miller, 2B
Drafted: 3rd Round, 2015 from Riverwood HS (GA) (SFG)
Age 22.4 Height 5′ 11″ Weight 190 Bat / Thr R / R FV 40

Hit Raw Power Game Power Run Fielding Throw
40/50 50/50 40/45 55/55 45/50 40/40

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.

25. George Bell, OF
Drafted: 13th Round, 2018 from Connors JC (OK) (SFG)
Age 21.0 Height 6′ 4″ Weight 215 Bat / Thr R / R FV 35+

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.

26. Jandel Gustave, RHP
Signed: July 2nd Period, 2010 from Dominican Republic (HOU)
Age 26.6 Height 6′ 2″ Weight 210 Bat / Thr R / R FV 35+
Tool Grades (Present/Future)
Fastball Slider Command Sits/Tops
70/70 55/55 40/40 96-98 / 99

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.

27. Raffi Vizcaino, RHP
Signed: July 2nd Period, 2011 from Dominican Republic (SFG)
Age 23.5 Height 6′ 2″ Weight 235 Bat / Thr R / R FV 35+
Tool Grades (Present/Future)
Fastball Slider Curveball Changeup Command Sits/Tops
55/55 45/45 50/55 50/55 40/40 91-95 / 98

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.

28. Sam Wolff, RHP
Drafted: 6th Round, 2013 from New Mexico (TEX)
Age 28.1 Height 6′ 1″ Weight 204 Bat / Thr R / R FV 35+
Tool Grades (Present/Future)
Fastball Slider Curveball Changeup Command Sits/Tops
55/55 55/55 55/55 40/40 40/40 92-95 / 96

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.

29. Jose Marte, RHP
Signed: July 2nd Period, 2015 from Dominican Republic (SFG)
Age 22.9 Height 6′ 4″ Weight 180 Bat / Thr R / R FV 35+
Tool Grades (Present/Future)
Fastball Slider Changeup Command Sits/Tops
60/60 45/45 50/55 35/40 90-96 / 97

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.

Other Prospects of Note

Grouped by type and listed in order of preference within each category.

Power Bats
Diego Rincones, OF
Zach Green, 3B/1B
Sandro Fabian, OF
Jacob Heyward, OF
Kwan Adkins, OF

Rincones, 19, is a plump corner outfielder with quick, strong hands. He’s posted two consecutive years of strong offensive statistics (AZL and NWL) and has plus raw power, but he’s a corner-only guy with a high-maintenance build, so he’ll need to keep doing that. Green was a minor league free agent who had an average exit velo of about 95 mph through this season’s first month. He has plus-plus power and barely hits the ball on the ground (25% GB%). Fabian looked like a potential contact/power corner outfielder but his approach is just too aggressive and he’s posted sub-.300 OBPs for two years. Heyward, 23, is a bit older than most prospects at Double-A but he has plus raw power and athleticism. He needs to keep walking a lot to balance the strikeouts. Adkins was a two-sport athlete at Northwestern State (he played wide receiver as a junior) who didn’t have statistical success in college, but has so far flashed all-fields power against younger pro pitching.

Relief Potential
Sam Coonrod, RHP
Garrett Williams, LHP
Franklin Van Gurp, RHP
Kervin Castro, RHP

Coonrod touches 99 and has a pretty good cutter and curveball. Williams is a low-90s lefty with a plus curveball but he’s quite wild. Van Gurp could be a traditional sinker/slider reliever if he develops above-average command. Castro is a projectionless 20-year-old who throws hard (93-96 this spring) with flat, up-in-the-zone plane that’s suited for missing bats. His secondaries are raw, but he missed most of the last two years with injury.

Younger Sleepers
Ismael Munguia, OF
Ghordy Santos, INF
Andrew Caraballo, INF

Izzy Munguia is a tiny corner outfield prospect with great feel to hit. His power is limited. He’ll likely need to be a 7 bat to profile. Santos and Caraballo are each built like Jorge Polanco. Santos has plus bat speed and some low-ball ability. Caraballo has plus infield hands and actions and Eric thought he saw him breaking in a catcher’s mitt on the backfields.

System Overview

This rebuild could take a while. There’s probably a dominant, homegrown bullpen in this system but most of the pitchers who’ll be part of it are already in their mid or late-20s. There’s a huge timeline gap between that group and the more exciting, potentially impactful group of teenagers (mostly bats) who are, by and large, currently in rookie and A-ball. Parlaying current big leaguers and upper-level prospects into long-term assets will be an important part of accelerating a return to competitiveness. That means nailing a seemingly imminent Madison Bumgarner trade. Scouts from opposing clubs are already deviating from their normal coverage to get extra looks at the left-hander so their teams have as much info as possible as we approach June and July.

Now that the org is under new leadership, the way talent is acquired and developed will change, but we’re not yet sure exactly how. It seems as if early priorities involve throwing fringe roster guys like Connor Joe, Aaron Altherr, and Breyvic Valera at the wall to see who sticks. Expect the Giants to try to find diamonds in the rough on the waiver wire who they’ll likely look to flip for long-term help rather than keep around.

We’ve seen Giants personnel at amateur games with the same model camera we’re using to take high-speed video, so they’re proactively entering that space. It’s likely their new Ops leader, Farhan Zaidi, will bring Dodger player dev concepts with him to San Francisco because the Dodgers have been so good at improving their players, but some of LA’s more prominent scouting tendencies (injured arms, toolsy college hitters with contact red flags, talent from Mexico) will be harder to replicate effectively because the Dodgers still exist in those spaces, too.
