Graham Spraker will be available when this year’s lockout-postponed Rule 5 draft is eventually held. The 26-year-old right-hander wasn’t added to the Toronto Blue Jays 40-man roster prior to last month’s deadline. While this was not exactly a surprise — the former 31st-round draft pick out of a DII school has never graced our prospect rankings — Spraker is nonetheless coming off an eye-opening season. In 31 relief outings, all but one of them at Double-A New Hampshire, the erstwhile Quincy University Hawk logged a 2.62 ERA and fanned 65 batters in 46-and-two-thirds innings.

Spraker’s breakout culminated in an award-winning stint in the Arizona Fall League. Pitching for the Mesa Solar Sox, the righty threw 11-and-a-third scoreless innings, allowing just four hits and a pair of walks, with 17 strikeouts. He was named the AFL’s Reliever of the Year at the conclusion of the campaign.

All that aside, just who is Graham Spraker?

“I am who I am,” the righty responded when asked about his pitching M.O. “I’ve changed a lot every year. I’m a pretty adaptable player — that’s why I’ve had success — but I feel that I’ve found a good blueprint now. It’s something I’m going to try to stick to for the rest of my career.” Read the rest of this entry »

Jeremiah Jackson made meaningful developmental strides this season. More mental than mechanical, they came amid an injury-interrupted campaign that saw him miss 11 weeks with a torn quad. Playing almost exclusively with the Low-A Inland Empire 66ers, the 21-year-old middle infield prospect homered 10 times while putting up a healthy 128 wRC+ over 218 plate appearances.

How satisfied was he with his performance?

“Satisfied is a word you kind of don’t use in baseball,” said Jackson, whom the Los Angeles Angels drafted 57th overall out of a Mobile, Alabama high school in 2018. “But under the circumstances, I was happy with how I played when I did play. I obviously could have been better, but I’m by no means mad. I learned a lot.”

Jackson feels that his time on the shelf — he was out from late June until early September — contributed to his education. Having more time on his hands allowed him to take a step back and study pitchers throughout the course of a game. How are they attacking certain hitters? What are they seeing that makes them want to throw a certain pitch? What are their mindsets on the mound?

Translating those observations to the batter’s box remains the objective. Read the rest of this entry »

Buddy Kennedy came two steps closer to following in his maternal grandfather’s footsteps this year. Splitting his first full professional season between High-A Hillsboro and Double-A Amarillo, the 23-year-old Arizona Diamondbacks infield prospect slashed a robust .290/.384/.523. Moreover, his right-handed stroke produced a 141 wRC+ and 22 home runs in just 406 plate appearances.

Don Money’s career high in home runs, which came in 1977, was 25. Himself a right-handed-hitting infielder, Money made four All-Star teams and put up a 106 wRC+ while playing with the Philadelphia Phillies (1968-72) and the Milwaukee Brewers (1973-83). Like his grandson, his primary position was third base.

A native of Millville, New Jersey — he and Mike Trout attended the same high school — Kennedy was Arizona’s fifth-round pick in the 2017 draft. Well before that time he was receiving sage advice from the family patriarch — advice that continues to this day.

“Ever since I was young he’s given me perspectives that most guys don’t have,” said Kennedy. “He helped teach me about the professional side of the game early on, so that I could go about my business the way I’m supposed to, instead of just going out there and playing without a purpose. He’s a great source. I love him. We sit down to talk baseball every time I get home.” Read the rest of this entry »

Ryan Kreidler isn’t the same hitter that Eric Longenhagen and Kevin Goldstein described when they put together our Detroit Tigers Top Prospects List last spring. The 24-year-old (as of last month) shortstop no longer possesses a “conservative, contact-oriented approach coupled with limited raw power.” Thanks to remaking his mindset and mechanics, Kreidler crushed 22 home runs this season while slashing a solid .270/.349/.454. Making those numbers all the more impressive is that the 2019 fourth-rounder out of UCLA put them up between Double-A Erie and Triple-A Toledo in his first full professional season.

His collegiate and short-season output had been that of a contact-oriented hitter. Kreider went deep 16 times in his three years as a Bruin, and just twice in 257 plate appearances with the New York Penn-League’s Connecticut Tigers in 2019. Dissatisfied with the dismal level of production, he went back to the drawing board.

“I wasn’t hitting the ball in the air very much,” said Kreidler, who according to Longenhagen and Goldstein lacked athleticism in the batter’s box. “I made some changes over [the 2019] offseason, then got a chance to work on them when I was home during COVID.”

The Davis, California native turned to Los Angeles-based hitting instructor Doug Latta for guidance. Read the rest of this entry »

J.T. Hintzen is a reliever with a five-pitch arsenal. Atypical as that is — most bullpen arms don’t feature such a wide array of offerings — it’s one particular pitch that sets the 25-year-old right-hander apart from his peers. Hintzen’s varied mix includes the increasingly-rare knuckleball.

More on that in a moment.

Hintzen is as unheralded as he is unique. A 10th-round pick in 2018 out of Florida Southern College, the Greenwich, Connecticut native remains under the radar despite a 3.38 ERA and 204 strikeouts in 162-and-a-third professional innings. Back in action this summer following last year’s COVID-cancelled minor-league season, he logged a 3.88 ERA and a 12.3 K/9 over 58 innings with the Double-A Biloxi Shuckers.

Hintzens arsenal comprises two sliders — “one that sweeps across the zone, and one that’s more downward” — a changeup, a four-seam fastball with good ride, and the knuckleball. Effectively tunneling his heater and the sharper of his breakers is a big key to his success.

“[The slider] comes out of the same arm slot as my fastball, and pairing the two usually gets hitters out, because they can’t read it well,” explained Hintzen, who augmented his 36 regular-season appearances with 11 more for the Arizona Fall League’s Salt River Rafters. “It comes out hard. If I throw my fastball 90 mph, my slider is probably coming out around 85. The sweeping one is more like 80 mph. I’ve gotten up to 20-plus inches of horizontal break with that one — straight across the zone like a frisbee — whereas the [harder one] is more like five to 10, but more downward. I’m throwing them on two different planes.”

Hintzen delivers his pitches from a lower arm slot — his release point will creep below five feet — and the spin he gets on his fastball ranges between 2,400 and 2,500 RPMs. And then there’s the pitch that rotates hardly at all. Read the rest of this entry »

Joe Gray Jr. possesses some of the best raw talent in the Milwaukee Brewers system. A second-round pick in the 2018 draft out of Hattiesburg (Mississippi) High School, the 21-year-old outfielder is coming off a season where he slashed .252/.355/.499 between Low-A Carolina and High-A Wisconsin. Augmenting those numbers were 23 stolen bases, 22 doubles, nine triples, and 20 home runs in 479 plate appearances. Called “a high-risk/reward prospect” by Eric Longenhagen earlier this summer, Gray Jr. capped off his 2021 campaign by competing in the Arizona Fall League with the Salt River Rafters.

Currently Milwaukee’s No. 12 prospect, per The Board, he discussed his development during the penultimate week of AFL action.

David Laurila: To start, who are you as a hitter?

Joe Gray Jr.: “I’d say I’m still figuring it out. I’m still young and learning to let my body work how it works and not be restricted. That’s what I’m trying to do right now. But I know what I can do. I’m a guy who can drive the ball when I get a pitch out over the plate. I’ve just got to play to my strengths. As I get older and more experienced, through repetitions and at bats, I know it will come.

“Again, I can’t necessarily put too much into ‘who I am.’ I’m not going to put pressure on myself, trying to make sure I’m down with it tomorrow or even next week. This is my first full season, so I’m still trying to figure myself out.”

Laurila: Can you say a little bit more about learning your body, and not restricting yourself? Your level of athleticism is obviously high. Read the rest of this entry »

Carlos Cortes might be the most-unique player available in the upcoming Rule 5 draft. A 24-year-old multi-positional player whom the New York Mets took in the third round of the 2018 draft out of the University of South Carolina, Cortes is ambidextrous. When stationed at second base, he throws right-handed. When patrolling the outfield, he throws from his natural left side.

The both-ways ability dates back to his formative years in the Orlando area.

“When I was around eight years old, my dad told me that my chances of playing a position would increase if I was able to throw right-handed,” explained Cortes, who currently stands 5-foot-7. “I didn’t really like it at first — he kind of forced me to do it — but by the time I got to high school, I was pretty natural with it. I caught my first couple years, then played second my junior and senior years, as well as in the outfield. I kind of played everywhere.”

Everywhere included the mound. Throwing left-handed, Cortes sat comfortably in the high-80s and became Lake Howell High School’s closer in his final prep season. Then came his collegiate experience. Eschewing the opportunity to sign with the Mets as a 20th-round pick in 2016, Cortes proceeded to play primarily in the outfield with the Gamecocks, putting up a .906 OPS along the way.

R.J. Dabovich was a strikeout machine in his first professional season. Overpowering the opposition with a two-pitch mix, the 23-year-old right-hander fanned 62, and allowed just 15 hits, in 32-and-a-third innings between High-A Eugene and Double-A Richmond. The 2020 fourth-round pick out of Arizona State University put up those numbers in 31 relief outings, a workload that was truncated by five weeks on the shelf due to a mild back strain. Currently the No. 26 prospect in the San Francisco Giants system, Dabovich represented the Scottsdale Scorpions in Saturday’s Fall Stars Game.

David Laurila: You had the highest strikeout rate (48.8%) in the minors this year. Are you at all surprised by how dominant you were?

R.J. Dabovich: “I am a little bit. I mean, I’d never really been ‘a strikeout guy.’ At Arizona State, I was a starter in my sophomore year and was like eight or nine Ks per nine. Nothing too crazy. Moving to the bullpen bumped it up a little bit [13.1 per nine], but nothing like it was this year.

“After I got drafted by the Giants, I was given this pitch plan for what they wanted me to do. They said that my K-rate would increase, but I had no idea it would jump like it did. So I definitely surprised myself by how well I executed my plan, the plan they made for me.”

Kendall Graveman surprised me with something he said during the ALCS. Talking with the 30-year-old, then-Houston Astros reliever, I learned that it was only recently that he truly learned a breaking ball. As the now-free agent put it, “I didn’t throw one forever, really. I didn’t know how to spin it.”

He spun a lot of good ones during the 2021 season. Throwing more breakers than at any point in his career, Graveman had 61 strikeouts and allowed just 35 hits in 53 relief appearances comprising 56 innings. Toeing the rubber for both the Seattle Mariners and the Astros — he switched teams shortly before the July trade deadline — he logged a 1.77 ERA and a 3.19 FIP. Opponents slashed just .130/.193/.196 against the right-hander’s slider.

Graveman signed a free agent deal with the Mariners in November 2019, six-plus after entering pro ball as Toronto’s eighth-round pick out of Mississippi State University. Why did it take him so long to master the intricacies of such an important facet of his craft?

“Some pitching coaches have a very good understanding of how to teach something, and I ran into some people over in Seattle who taught me how to throw a breaking ball,” said Graveman. “Since when I was young, I would cup out of the hand and that would get me on the outside and not creating good spin. That’s as opposed to throwing it like a fastball. We started taking it out like a fastball and letting the wrist be loose, and started seeing positive signs with the spin.”

I asked the Alexander City, Alabama native if he could elaborate on the adjustment. Read the rest of this entry »

Mark Vientos profiles as a middle-of-the-order basher in a big-league lineup. Currently the No. 5 prospect in the New York Mets system, the 6-foot-4, 205-pound third baseman is coming off a season where he slashed .281/.352/.581 and hit 25 home runs in just 349 plate appearances between Double-A Binghamton and Triple-A Syracuse. One of the youngest players in his draft class when he was taken 59th overall in 2017 out of Plantation, Florida’s American Heritage High School, the right-handed hitting corner infielder put up those numbers at 21 years of age.

Vientos discussed his approach and early-career development prior to the end of the minor-league campaign.

David Laurila: How would you describe yourself as a hitter?

Mark Vientos: “I like to consider myself an all-around type of hitter. A lot of people consider me just a power threat, but I feel like I can hit for average and power. As time goes on, and as I mature at the plate, I think my patience and discipline is going to be a lot better. I’m learning how they’re pitching me at these levels. Hopefully soon I’ll be at the major-league level and will be figuring out how they pitch me there.

“How teams pitch you differs, too. How the Red Sox [affiliate] pitches you might differ from how the Blue Jays pitch you. It’s about recognizing those things, but for the most part I’m looking for a fastball, because that’s the best pitch I could hit. I handle the fastball well.”

Laurila: Your writeup in this year’s Baseball America Prospect Handbook said that while you can square up most fastballs, you struggle with spin from right-handers. To what extent is that true? Read the rest of this entry »
