As the baseball calendar turned over to 2017, Alex Reyes was arguably the best pitching prospect in the game and set to be the brightest young star on a likely playoff contender. Instead, he would need Tommy John before all of his teammates had even arrived for spring training. It was a disappointing twist in an already eventful, young career.

Eric Longenhagen Prospects Chat: 11/7

12:02
Eric A Longenhagen: Okay, we’re on. Pretty sure I’m headed to Mesa for this afternoon’s AFL game (not 100% on who the starters will be, the AFL has just decided to stop posting probables, apparently) so as is typical during AFL time, we’re keeping tight to an hour. Let’s boogie.

12:02
Josh: How close are Kyle Tucker and Garrett Whitley to the majors? Both seem to be getting fast tracked

12:03
Eric A Longenhagen: Tucker might get there next year in the event of injury but Houston has a glut of upper-level outfielders even after dealing Teoscar. Whitley was in Low-A last year so I disagree that he’s being fast tracked. he was a raw HS bat from the Northeast, not a guy who’s typically going to move quickly.

12:03
Whatup: Adbert Alzolay (sp?) – what his long term potential?

12:04
Eric A Longenhagen: Chance to be a mid-rotation starter. 93-96, was 95-97 in Fall Stars game. Has two viable secondaries. I’m a fan.

12:05
David: Anything thoughts on Yankees’ Chris Gittens and Nick Nelson? Both seem like high upside lottery tickets, anything we can get excited about?

Eric Longenhagen Spooky Prospects Chat

12:18
Eric A Longenhagen: Good morning, folks. Lots to squeeze in on my end today (I think I get Taylor Hearn and Tyler Beede in Scottsdale today) so we’ll probably hold tight to an hour. Let’s begin

12:19
Philip: Do you prefer austin Allen to Josh Naylor?

12:19
Eric A Longenhagen: Nope

12:19
Evan Longoria : Do you know much about Ronaldo Hernandez?

12:20
Eric A Longenhagen: Strong 19-year old Colombian catcher in Tampa’s system. Has power, catching is a work-in-progress but that’s fine because he’s a converted infielder. He made Rays list last offseason.

12:21
Chris: How good will Florial, Abreu, and Estrada be?

Eric Longenhagen Prospects Chat: All the Marbles

12:02
Eric A Longenhagen: Howdy, everyone. Let’s just dive right in.

12:02
Greg: Do you think Alex Jackson will atleast be a MLB back up type, 4th OFer/3rd catcher type, power off bench?

12:04
Eric A Longenhagen: I think there’s enough going on that he has some kind of big league role, yes. And I don’t rule him out as a regular just yet. I’ve probably said this before, but evaluating catcher defense in the AFL is really tough. Guys are ground down from a long season and also suddenly catching an entirely new staff. I’ve had many scouts warn me of mistakes they’ve made by weighing AFL looks at catchers too heavily.

12:04
Dan: In curious if you could provide some semi historical context for the relative wave of “meh” reviews we are getting on Maitan. In terms of other top international amateurs, I have to imagine many struggle as 17 year olds, and many have body concerns. Does this feel more noteworthy just because of the “generational talent” hype?  Is this a relatively normal level of struggle?

12:08
Eric A Longenhagen: Sure. Yes, 17-year olds who come here and are asked to rapidly assimilate to our culture (which includes access to a lot of food that isn’t good for you which, at age 17, I l consumed frequently) often struggle to do so. And that combined with the difficulty of being a pro baseball player often leads to some unflattering growing pains. So, while I’d rather have scouts telling me he looks amazing, this isn’t something to lose sleep over just yet. At least I don’t think so.

Hooha: Who are you most interested to see in Arizona?

(Mostly) East Valley Instructional League Notes

Periodically, I’ll be posting notes from in-person observations at Fall Instructional League and Arizona Fall League play. Each are essentially the scouting calendar’s dessert course, both in their timing and sometimes dubious value. I take bad fall looks with a large grain of salt as players are sometimes fatigued, disinterested, put in difficult situations purposefully so that they’ll fail, or some combination of these or other bits of important context. With that in mind here are links to past notes followed by this edition’s.

Previously
9/20 (TEX, SD)
9/21-9/23 (CHA, MIL, SD, TEX)
9/24-9/25 (CHA, CIN, LAN, TEX)
9/27-10/2 (ARI, LAA, OAK, SF)

Instructional League plays is more or less complete. What follows represents my looks from the schedule’s last couple weeks. As the short season progressed, I made an effort to see teams whose minor-league complexes are located in the Phoenix Metro Area’s eastern reaches. Chronological drafts of this post were confusing, as many of these teams play against one another due to ease of travel. As such, notes in this edition are organized by team instead of date.

Colorado 2B Shael Mendoza had a monster summer in the Pioneer League, slashing .362/.412/.519 while swiping 25 bases in 55 games. While Mendoza has strong hands and wrists that lead to loud contact when he squares a ball up, he has some issues that dilute the quality and amount of contact he makes. He’s often out on his front foot early or excessively and his bat isn’t in the hitting zone for very long. He’s also a fringe athlete without great actions at second base. I do think there’s some physical ability with which to work, evident in Mendoza’s power on contact, but I think there’s significant risk that his 2017 on-paper performance was a bit of a mirage.

Instructional League Notes from Oakland, Anaheim, San Francisco and Arizona

Periodically, I’ll be posting notes from in-person observations at Fall Instructional League and Arizona Fall League play. Each are essentially the scouting calendar’s dessert course, both in their timing and sometimes dubious value. I take bad fall looks with a large grain of salt as players are sometimes fatigued, disinterested, put in difficult situations purposefully so that they’ll fail, or some combination of these or other bits of important context. With that in mind here are links to past notes followed by this edition’s.

Previously: 9/20 (TEX, SD), 9/21-9/23 (SD, CHW, MIL, TEX), 9/24-9/25 (CIN, TEX, LAD, CWS).

9/27

The talent at the Angels complex in Tempe has significantly improved in the last calendar year due to an influx of projectable Latin American pitching and the bevy of athletic outfielders the club has added mostly through the draft. Among those pitching this fall is RHP Stiward Aquino, a 6-foot-6, 18-year old Dominican righty. Aquino’s fastball sat in the 87-92 range but it will bump 95 and there might be more coming as he fills out. His delivery isn’t especially graceful or powerful right now — a byproduct of Aquino’s immature physicality – but it is deceptive and there’s some changeup feel here already. Aquino slots in near the bottom of a suddenly deep hierarchy of low-level Angels pitching prospects, but is worth following.

Chris Rodriguez threw this day as well and struggled. He sat 92-94 with his fastball and was up to 96, but his secondary stuff simply wasn’t as sharp as it had been earlier in the year. Minor League Rule 5 pick Adrian Almeida sat 94-96 with an average curveball, but he continues to struggle with control.

Jo Adell has returned to action in the outfield after DH’ing throughout the summer. He wasn’t throwing well this spring prior to the draft which was disconcerting to some, as Adell was touching 94 as a pitcher the summer before. His arm strength still hasn’t returned — he’s throwing with a 30 arm right now. He looks great in the batter’s box and is running well enough to continue playing center field for a while, but he’ll be limited to left field if his arm strength doesn’t return.

Giants OF Sandro Fabian had a rough year at Low-A, largely due to a hyper-aggressive approach that led to a 2% walk rate. He’s making among the loudest contact at Instructional League, with multiple exit velocities in excess of 100 mph during my in-person looks. He tracks pitches well, has great timing and bat control and can drive balls to all fields. There’s special offensive talent here, and I’m still buying stock in Fabian even after a horrendous season.

With the Dbacks in the playoffs, guys like Chris Owings needed at-bats to stay ready, just in case.

10/2

The Diamondbacks play precious few instructional league games this fall– just three, and one of them isn’t open to the public – and as such are a priority on the days that they do. They faced Oakland in their opener. Arizona prospects were robbed of some at-bats this year due to their playoff berth as Ildemaro Vargas, Chris Owings, Yasmany Tomas and Jeremy Hazelbaker have required at-bats to stay sharp in case they’re suddenly needed by the big club. Owings was rusty on this day and looked a bit slow, running in the 4.3s from home to first instead of his typical blazing 4.1.

Arizona LHP Jordan Watson has perhaps the best breaking ball I’ve seen here this fall, a true plus-plus hammer with bat-missing bite. He didn’t throw many, instead focusing on a low-90s fastball and below average changeup during his outing. He’s 24 and hasn’t pitched in a full season league yet due to injury, but he could be a quick-moving lefty relief piece next year.

Oakland RHP Richard Morban sat 90-93 with a fastball that missed bats up in the zone. He also flashed an above-average changeup in the mid-80s and a fringey, low-80s curveball. Morban turns 20 on Christmas Eve and is a modestly framed 6-foot-2. Though not especially explosive, he is athletic and repeats his delivery, and I think he’ll throw enough strikes to start. He has back-end starter ingredients.

Athletics INF prospect Marcos Brito has shown terrific quickness in his bat, as well as his defensive footwork and actions. He diagnoses balls and strikes consistently and has good feel for opposite field contact, though he struggles to turn on and drive the ball to his pull side.

hscer: what’s up with barreto

12:03
Eric A Longenhagen: Just a 21-year old struggling with his initial taste of the toughest baseball league on the planet. I don’t think he’s a SS but think he’ll hit enough to play wherever he ends up, which will still likely be an up-the-middle position.

Hunter Greene, Rangers Conversion Arms, and More from Instructional League

Periodically, I’ll be posting notes from in-person observations at Fall Instructional League and Arizona Fall League play. Each are essentially the scouting calendar’s dessert course, both in their timing and sometimes dubious value. I take bad fall looks with a large grain of salt as players are sometimes fatigued, disinterested, put in difficult situations purposefully so that they’ll fail, or some combination of these or other bits of important context. With that in mind here are links to past notes followed by this edition’s.

Previously: 9/20 (TEX, SD), 9/21-9/23 (SD, CHW, MIL, TEX).

9/25

Cincinnati hosted Texas in the Reds’ instructional-league opener, and the game featured several pitchers with position-player backgrounds. The headliner was Hunter Greene, who sat 99-101 with a fastball spinning at a rate between 2200 and 2300 over two innings. He used both of his breaking balls quite frequently, first leaning on an inconsistent curveball in the low 80s and, later on, an upper-80s slider. The curveball flashed above average but its depth and bite varied. Greene’s slider was short and fringey, though he threw both breakers for strikes multiple times. His fastball command was less consistent, however, and Greene was hit hard (twice quite literally, by two second-inning comebackers), surrendering six runs.

Greene was followed by righty Wyatt Strahan, a 24-year-old reliever who hasn’t gotten out of A-ball yet, mostly due to injury. He was up to 96 on Monday with a plus slider and violent delivery. If he can stay healthy, he’s a potential bullpen contributor.

Among those on the mound for Texas were former position players James Jones and Jairo Beras. Jones was a two-way player on his high-school team in Brooklyn and again at Long Island University. The Mariners drafted him in the 2009 draft’s fourth round and he made the majors as a speed-first outfielder in 2014, stealing 27 bases in 28 attempts that year. Sent to Texas as part of the 2015 Leonys Martin trade, Jones continued toiling away at Triple-A through much of 2016 without offensive success and began to transition to pitching late last year. He blew out after a few pitching appearances late in 2016 and needed Tommy John surgery.

Jones is now back on the mound and pitching with interesting stuff, sitting 92-94 with a bit of late wiggle and a fringey curveball and changeup. His lower arm slot allows right-handed hitters to see the ball early and they have teed off on Jones in two looks I’ve had at him this fall.

Though it may not be Jones himself, this is what I think a realistic two-way player looks like, someone who can competently play a niche role on both sides of the ball. In Jones’ case, that means getting lefties out as a bullpen arm while also acting as a defensive replacement and pinch-runner. The chances of such a creature existing at all would be aided by roster expansion, something December’s CBA negotiations nearly yielded.

Beras sat 94-96 with an average slider. He isn’t as athletic as Jones but throws hard and is new to pitching. Both conversion arms are longshots but have major-league-caliber arms that need late-career refinement.

9/26

Tuesday, the Dodgers and White Sox had simultaneous home instructional-league games at Camelback Ranch for the only time this fall. Their fields are close enough to one another that one can stroll back and forth between games. I began on the Dodgers’ side, where they took on Cincinnati.

Reds third-rounder Jacob Heatherly sat 90-92 and commanded that pitch as well as his average curveball and changeup. He lacks any physical projection and, except for perhaps a bit of breaking-ball and changeup progression from pro reps and instruction, the cement is largely dry on his stuff. Realistically, Heatherly projects as a No. 4 or 5 starter, but his ceiling will be dictated by the level of command he’s able to develop. He’s advanced in that regard and could move quickly. Heatherly, who turned 19 in May, signed for $1 million.

SS Jeter Downs, the Reds’ comp-round pick from June, has also been impressive. Downs sprays hard contact to all fields and has shown enough arm strength to stay on the left side of the infield. I’ve yet to see his range and athleticism challenged, but what I’ve seen is pretty good.

Dodgers 17-year-old LHP Robinson Ortiz was 90-93 with bat-missing life and feel for a breaking ball that flashed above average. He’s listed at 6-foot-4 on the instructional-league roster but he’s closer to an even 6-foot. Though short, Ortiz is well built and has a strong, voluptuous lower half. His arm action is a bit long, but I generally like his delivery and athleticism enough to project him as a starter. Well-built 17-year-olds with good fastballs and breaking-ball feel are typically being talked about as top-50 draft picks, even if they’re a little short.

Want more height/weight fun? RHP Alfredo Tavarez was listed at 6-foot-5, 190 this year but is listed close to 250 on the instructional-league roster and he’s every bit of that. He put up big numbers in the AZL, striking out 47 hitters in 30 innings, but only sits in the upper 80s with his fastball. Tavarez does have a potential plus breaking ball but will need to drastically improve his command if he’s to survive with this kind of velocity.

On the White Sox side, Chicago first-round 3B Jake Burger had issues with throwing accuracy but took good at-bats and made some loud contact. I remain skeptical of his chances of staying at third base but do think he’ll hit. I recorded multiple below-average pop times from C Zack Collins, all in the 2.05-2.10 range. Like Burger, though, he takes great at-bats, rarely offering at pitches off the plate and showing easy pull power.

Gary: I’m a Braves fan nervous about everything right now. Should I be?

12:05
Eric A Longenhagen: Depends what ‘everything’ is. They can’t take away the entire farm system, which is quite good, and frankly, people in other front offices don’t think Atlanta has lost a whole hell of a lot here. But it is ugly and this won’t be fun for anyone involved.

12:06
Birdlaw Esq: Do you foresee you job as it relates to getting info on J2 guys presigning as about to get much more difficult?
