When our Arizona Diamondbacks Top Prospects list was published in December, Eric Longenhagen described 24-year-old Kyle Amendt as “a late-blooming illusionist righty with a cut/rise fastball and a deceptive delivery.” Our lead prospect analyst went on to say that the physically imposing 6-foot-5, 255-pound hurler had “a 15% swinging strike rate in 2024, among the best in the org, even though his fastball sits just 88-92 mph.” Not fully sold on the total package — command is among the concerns — Eric assigned Amendt a 35+ FV.

His unorthodox style of pitching and minor league numbers nonetheless suggest a future role in a big league bullpen. Along with the aforementioned 15% swinging strike rate, the 2023 ninth-round pick out of Dallas Baptist University logged a 2.86 ERA, a 2.38 FIP, and a 40.3 K% over 44 innings across High-A, Double-A, and Triple-A. And his delivery is indeed unique. Eric called it “over-the-top trebuchet arm action,” adding that Amendt “hides the ball forever.”

Currently a non-roster invitee at D-backs camp, Amendt discussed his delivery and three-pitch arsenal during the Arizona Fall League season.

David Laurila: I’ve heard that you have an unorthodox delivery. How would you describe it?

Kyle Amendt: “Like a high left-handed slot as a righty. My curveball is a left-handed curveball, and my fastball is anywhere from an 11:45 to a 12-[o’clock] tilt. Everything looks like it’s coming from directly over my head.”

Triston Casas is making some changes with his left-handed stroke, and he’s doing so with the Green Monster in mind. The Boston Red Sox slugger has historically used the entire field — his pull-center-oppo numbers last season were 38.5%, 38.5%, and 23.0%, respectively — but he wants to take even better advantage of his home park. Bashing with arms bent will be part of that process… at least for now. Compared to his many of his contemporaries, Casas can be a bit of chameleon when it comes to fine-tuning his swing.

Always engaging when discussing his craft — last summer’s Triston Casas Talks Hitting Training and August 2023’s Triston Casas Embraces the Science of Hitting are good examples — the 25-year-old first baseman discussed his current efforts at Red Sox camp earlier this week.

David Laurila: You’re making some adjustments at the plate. What are they?

Triston Casas: “It’s more an approach of keeping my swing inside my frame. I want to have the angles of my body — my hips and my shoulders — in alignment, and try to make sure that I’m making contact inside my body. I want to feel like I’m hitting with my arms bent at a certain point.

“As a hitter, you need that triple extension. Your wrists, your front leg, and your back hip are all perfect, at the right time, as you’re making contact. That’s where you get the power.”

Hunter Bigge’s baseball career was in limbo when he graduated from Harvard University in 2021 with a degree in physics. Drafted in the 12th round by the Chicago Cubs two years earlier, the 26-year-old right-hander had scuffled in High-A and was unsure if he should continue to pursue his boyhood dream or move on to a career outside of baseball. Returning to the Ivy League institution to complete his studies following that difficult season gave him options, but he still loved the game.

Fast forward to 2024, and Bigge was thriving in the big leagues.

Bigge debuted with the Cubs on July 9, then a few weeks later was dealt to the Tampa Bay Rays along with Ty Johnson and Christopher Morel in exchange for Isaac Paredes. He excelled in both uniforms. With 15 of his 19 appearances coming after the trade, Bigge worked 17 1/2 total frames, fanning 24 batters while allowing 17 hits and just five free passes. Moreover, he posted a 2.60 ERA, a 2.76 FIP, and a 32.9% strikeout rate. His heater played a huge role in his success. At 97.5 mph, it ranked in the 94th percentile among his contemporaries.

Bigge discussed his path to the big leagues, and his approach on the mound, during the final weekend of the 2024 season.

David Laurila: Let’s start with one of my favorite icebeaker questions: Do you approach pitching as more of an art, or as more of a science?

Hunter Bigge: “I approach it more as an art. I’m pretty analytical, but I don’t think the analytical part of my brain is the one that allows me to play the best. I try to come at it with a little more flexibility. I let the science inform the high-level decisions, but when I’m out there, I’m thinking of it more like a dance with the hitter.” Read the rest of this entry »

Bubba Chandler is on track to join Paul Skenes and Jared Jones in the power department of the Pittsburgh Pirates starting rotation. Equipped with an elite upper-90s fastball and a solid array of secondary offerings, the 22-year-old right-hander has emerged as one of baseball’s highest-ceiling pitching prospects. As Eric Longenhagen notes in our forthcoming Top 100, Chandler, who was a two-sport, two-way player as an amateur and began focusing solely on pitching in 2023, is still developing, but “so far, [it’s] going as well as could have been hoped when he was drafted, and he’s tracking like a mid-rotation starter.”

His 2024 season offered ample evidence of his ability to overpower hitters. In 119 2/3 innings between Double-A Altoona and Triple-A Indianapolis, Chandler fanned 148 batters while surrendering just 81 hits. Along with a 30.9% strikeout rate and a .187 batting-average-against, he logged a 3.08 ERA and a 3.10 FIP. Moreover, he displayed improved command. The 2021 third-round draft pick out of Bogart, Georgia’s North Oconee High School lowered his walk rate from 10.5% in 2023 to a stingier 8.6% last season.

Chandler discussed his developmental strides, and the bat-missing arsenal he takes with him to the mound, earlier this month.

David Laurila: What have you learned about pitching since getting to pro ball?

Bubba Chandler: “The number one thing has been command. You can have great stuff, but I’ve noticed that the more I’ve gone up [minor league levels], the less guys swing at crappy pitches. In Low-A, you can throw a slider way out of the zone, and a lot of times you’re going to get a swing. If you throw a slider way out of the zone in Triple-A, especially if you didn’t set that pitch up, you’re not even going to get a lean over, or a budge, on it.

“Learning how to set pitches up has been a big thing for me. Setting them up, tunneling, and just how pitches move… but really, the command part is really what has helped make me better.” Read the rest of this entry »

The Seattle Mariners currently have one of baseball’s best farm systems, and its strength differs markedly from that of the big league roster. Pitching-rich at the major league level, it’s Mariners position player prospects who populate the top tier of our rankings. That’s welcome news — at least on paper — for a Seattle team that has recently excelled at keeping runs off the board, but has too often struggled to score.

Justin Toole is front and center in the organization’s quest to graduate productive bats into the parent club’s lineup. Brought on as director of player development following the 2022 season, the 38-year-old Council Bluffs, Iowa native has both the background and the acumen to help make that happen. Prior to coming to Seattle, Toole played seven professional seasons, then served four years as a minor league hitting coach, followed by three as a major league hitting analyst. All of his pre-Mariners experience came with Cleveland.

Toole discussed several of the system’s most promising prospects prior to heading to Arizona for the start of spring training.

David Laurila: What is the current strength of the system?

Justin Toole: “From a player development standpoint, I think the strength is the individuality with how we handle our players. When we get people into our system, we figure out their strengths, we figure out their weaknesses, we help them understand their identity. We work with our players to get a feel for where they think they are, and where they want to go.

“Our group has done an unbelievable job of creating good player plans that are clear, that are are easy to follow. They’re simple. I think that’s kind of been the strength of our player development group. Of course, any good player development group is going to be good because of the scouting group. They bring in good players, players that fit what we want to do, and who we want to be.” Read the rest of this entry »

Walker Jenkins is more than just the top-rated prospect in the Minnesota Twins system. Drafted fifth overall in 2023 out of Southport, North Carolina’s South Brunswick High School, the soon-to-turn-20-year-old is one of the game’s top prospects. His left-handed stroke is a big reason why. As Eric Longenhagen notes in Jenkins’ forthcoming Top 100 prospect report, the outfielder “has exciting feel to hit and barrel control. He tracks pitches exceptionally well and can move his hands all over the strike zone.” Longenhagen goes on to note that while Jenkins is likely a left fielder (the Twins have primarily deployed him in center so far), he “should hit enough to be a heart-of-the-order hitter and impact regular regardless of position.”

His first full professional season was impressive. In 368 plate appearances split across four levels — he finished the year in Double-A — Jenkins had a 139 wRC+ to go with six home runs and a .282/.394/.439 slash line. Moreover, he swiped 17 bases in 20 attempts.

Jenkins discussed his hitting approach in the final week of January.

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

Walker Jenkins: “Above all things, I’m a hitter who is going to go up there and try to get my best swing off. You have guys that get categorized as, ‘Oh, they’re hitters, but they have no power,’ while for others it’s, ‘They’re all power, but no hit.’ I want to be a good hitter. I’m going to hit first, and when I get my A-swing off, that’s when my power is going to come.

“If you can continuously hit the ball on the barrel, good things are going to happen. That’s what I try to do, because I don’t like striking out. I don’t like giving at-bats away. But when I get in a hitter’s count, I’m not going to get cheated.” Read the rest of this entry »

George Lombard Jr. is a promising prospect with a first-round pedigree. Drafted 26th overall in 2023 out of Gulliver Preparatory School in Pinecrest, Florida, the right-handed-hitting shortstop is also the son of former big league outfielder (and current Detroit Tigers bench coach) George Lombard. Assigned a 45 FV by lead prospect analyst Eric Longenhagen, the athletically gifted youngster is no. 4 on our recently released New York Yankees Top Prospects list.

The 19-year-old’s first full professional season was a mixed bag statistically. Over 497 plate appearances between Low-A Tampa and High-A Hudson Valley, Lombard logged a .231/.338/.334 slash line, a 99 wRC+, and 32 extra-base hits, five of which left the yard. Taking advantage of his plus wheels, he swiped 39 bases in 47 attempts.

Lombard discussed his game late in the 2024 season.

David Laurila: I’ve seen you listed at 6-foot-2, 190 pounds. How accurate is that, and where do you see yourself going forward?

George Lombard Jr: “I’m 6-foot-3 and around 205 pounds. I’ll put on some more weight in the next few years, and I think our goal will end up being around 215, maybe 220. We believe that I can still be fast as I put on weight, so we’re going to continue to do that. A lot of it will just come with physically maturing over time, and putting in the work in the weight room.” Read the rest of this entry »

Zach Dezenzo could play an important role for the Astros this year. The 24-year-old projects to be a “viable third baseman,” as Eric Longenhagen and Travis Ice wrote in Dezenzo’s prospect report in June, but depending on how Houston’s roster comes together — an Alex Bregman return remains a possibility — Dezenzo could also be used in left field. Indeed, at Astros FanFest on Saturday, manager Joe Espada said Dezenzo will get a lot of reps in left field during spring training.

Regardless of where he is stationed defensively, extra-base oomph will be the righty-hitting Dezenzo’s calling card. A 12th-round pick in 2022 out of Ohio State University, Dezenzo has 70-grade raw power that he is still learning to tap into in games (55 FV game power), according to our prospect team. Last season, he posted a 131 wRC+ between Double-A Corpus Christi and Triple-A Sugar Land. He made his big league debut in early August and was optioned a month later before getting called up again just before the end of the regular season. During his 19 major league games, he went deep twice while slashing .242/.277/.371 (84 wRC+) over 65 plate appearances.

Dezenzo discussed his development as a hitter when the Astros visited Fenway Park in August.

David Laurila: You didn’t get drafted your junior year, despite solid numbers [including a .933 OPS]. Why was that?

Zach Dezenzo: “Good question. I put together a pretty strong freshman season at Ohio State [in 2019] — freshman All-American honors — then the COVID season obviously got cut short. My junior year, I hit .302 with nine home runs, although we only played 42 games. I knew I was good, but I’m not sure that I did enough to raise many scouts’ attention. That’s probably kind of where I was at, needing one more year to show what I was truly capable of. But that’s OK. It all worked out perfectly fine.”

Laurila: You must have drawn some attention as a junior…

Dezenzo: “I did have some. The Astros were actually interested — they were probably the number one team in contact with me — so yes, there was definitely interest. It just didn’t pan out the way I wanted it to.”

Laurila: Jumping to your hitting profile, how does it now compare to when you signed? Are you mostly the same guy in the box? Read the rest of this entry »

Hunter Dobbins has emerged as one of the top pitching prospects in the Red Sox system. Selected in the eighth round of the 2021 draft out of Texas Tech University, the 25-year-old right-hander is coming off of a 2024 season in which he logged a 3.08 ERA and a 3.04 FIP over 125 2/3 innings between Double-A Portland and Triple-A Worcester. Assigned a 40+ FV grade by Eric Longenhagen after being added to Boston’s 40-man roster in November, Dobbins was called “a near-ready fifth starter prospect” by our lead prospect analyst back in July.

Dobbins discussed his repertoire and approach when the Red Sox held their annual Rookie Development Camp at Fenway Park earlier this month.

David Laurila: What have you most learned about pitching since getting to pro ball?

Hunter Dobbins: “I would say how to attack hitters. Every single year I’m learning how to follow our plan and execute that plan. I think I’ve taken a big step forward in that aspect. The pitch shapes are also getting a lot more consistent. Last year, a couple of my pitches would have almost two different movements. This year, I’m looking at having consistent movement so that I can go right at hitters. But overall, it’s more of the strategy side of things where I’ve learned the most.”

Laurila: How do you balance attacking weaknesses versus throwing your pitches where they tend to play best?

Dobbins: “I side more on sticking to my strengths. That said, I have five pitches. I have pitches that move in all different directions, so I’m going to take into account if a guy struggles on this half of the plate with pitches that move in this direction; I’m going to have a strength in that realm. But I’m also not going to shy away from something I know I can land, even if that is considered one of his strengths. I’m going to take my best ball versus his best swing and see what happens.”

Laurila: How many pitches did you have when you signed? Read the rest of this entry »

Back in early October, Termarr Johnson self-assuredly told MLB Pipeline’s Jim Callis that he is continuing to work on being “the best hitter in the world.” The 20-year-old Pittsburgh Pirates prospect didn’t put it quite that way when I spoke to him days later, but he did exude determination and confidence when addressing his craft. That’s understandable. Drafted fourth overall in 2022 out of Atlanta’s Mays High School, Johnson remains a high-ceiling hitter, albeit one whose developmental path hasn’t been as smooth as many had anticipated.

His 2024 season included both stumbles and strides. The 5-foot-7, 190-pound middle infielder logged a solid 121 wRC+ between High-A Greensboro (487 plate appearances) and Double-A Altoona (57), but as our lead prospect analyst Eric Longenhagen wrote last summer, Johnson’s “underlying contact data is pretty concerning.” Moreover, while his 15 home runs were indicative of plus power potential, the accompanying .386 slugging percentage was a bit underwhelming. Johnson’s left-handed stroke is unquestionably capable of causing damage, but further fine-tuning is needed before that can happen at the big league level.

Johnson discussed his approach to hitting shortly after the start of the Arizona Fall League season.

———

David Laurila: You’re still just 20 years old. Do you feel that you’ve settled into your identity as a hitter?

Termarr Johnson: “For sure. I feel like I have a pretty good swing, and I hit the ball hard pretty often, so I’m just trying to keep a good approach and bring the pitcher to me. I feel like that puts me in the best position possible. And to be honest with you, I’m a different hitter every at-bat. I’m a different hitter based on… like, every pitcher is different. Every pitch is different. Every situation is different. I’ll be a different hitter if there’s a runner on base and I’m trying to get him in, late in the game, or I’ll be a different hitter when I’m leading off the game.”

Laurila: That’s basically approach. What about mechanically? Read the rest of this entry »
