Spencer Arrighetti had just thrown a pair of impressive innings when I talked to him following a spring training start in Lakeland, Florida at the end of February. I admittedly didn’t know a ton about the 24-year-old at the time. I was aware that the Houston Astros had named him their 2023 Minor League Pitcher of the Year, and that he’d been taken in the sixth round of the 2021 draft out of the University of Louisiana at Lafayette, but that was mostly it. The only other thing I knew about Arrighetti — this from my perch in the press box — is that he throws a sweeper.

What I learned about the 6-foot-1, 205-pound righty from our postgame conversation is that he is anything but old school with how he approaches his craft. Analytics is Arrighetti’s second language, and when it comes to talking pitching, they are pretty much his first language. Now on the doorstep of the big leagues — he tossed 4 1/3 scoreless innings with the Triple-A Sugar Land Space Cowboys this past Friday — Arrighetti is a bona fide pitching nerd.

———

David Laurila: Are you into pitching analytics?

Spencer Arrighetti: “Absolutely. I was taught the data by the Astros, and they obviously know their stuff really well. I love the model that we have. I’ve definitely fallen in love with that aspect, so while the game itself is still more important, I fully acknowledge that we have the ability to train analytically now. We can use data to get better.”

Laurila: What have you learned about yourself since coming to pro ball?

Arrighetti: “I’d summarize it by saying that vertical approach angle is kind of indicative of how a pitch will perform. Fastballs are especially vertical-approach-angle dependent on where you should throw them. I’ve learned about that. I’ve also made an effort to improve vertical approach on my fastball, as well as improve spin axis and spin rates on my other pitches.

“There is also the usage data. I’ve found a really good way to utilize my pitch mix efficiently and effectively. Obviously, we’re always trying to fine tune that — the more you climb the ladder, the more it matters — and at this stage it’s especially important for me to have a concept of what’s going to be good against big league hitters.”

Laurila: Can a pitcher meaningfully improve approach angle, or is more a matter of optimizing what you have?

Arrighetti: “It’s a nice mix of both. You get special athletes who do special things, and there are certain things about a guy you won’t want to change, like his delivery. At the same time, you can absolutely chase it. I think I had a pretty decent vertical approach in college, and after being made aware of it, I made more of an effort to get behind and under the ball.

“We look at hop, and it matters a lot, but I don’t have good hop. My four-seam performs like it has hop, but it actually doesn’t have it. I throw it from… I like to call it ‘throwing it from the basement’ as opposed to throwing from above your head. That’s where you find the vertical approach that is more down to up. So, I think that you can make an effort to refine it. Obviously, you’re not going to take a guy that throws 100 [mph] with a steep vertical approach and tell him, ‘Hey, let’s try to flatten it out a little bit.’ You’re going to tell him, ‘Hey, throw 100. You’re fine.”

Laurila: Hand positioning at release plays into what you’re looking to do…

Arrighetti: “Absolutely. Edgertronic is pretty popular within the data room. You can see exactly where the ball is coming out of your hand, which gives you an idea of the timing of it. You adjust your wrist position based on that; you find that point on the ball where you want to be letting it go.”

Laurila: Have you altered any of your grips as a result?

Arrighetti: “I don’t throw a single pitch the same way that I threw it in college; I actually don’t throw many pitches the same way that I threw them in Low-A. We’ve been really good about finding grips and cues that complement my arm and the way I want to throw the ball. Because of that, I’ve been able to develop an arsenal that I’m really confident in. So yeah, I’ve made a lot of drastic changes — even this offseason. I made a big adjustment with my changeup grip. Grips are great until they’re not, and cues are also great until they’re not. When it’s time to adjust, you adjust. Sometimes the adjustment is big, and that’s OK.”

Laurila: Are any of your grips unique?

Arrighetti: “I would say that they are iterations of other pitches that guys throw really well. In general, the more that analytics have come along, the more we have a good idea of which grip will do what to the ball, and from what slot, horizontal approach, and vertical approach. So, not necessarily unique, but tailored to me.”

Laurila: Do you chase certain movement profiles?

Arrighetti: “Absolutely. I think everybody does.”

Laurila: Some guys claim they don’t…

Arrighetti: “The guys that claim they don’t are most likely guys who don’t love the data. Which is fine. There are big crowds of both. There are guys who think it has no place, and there are guys who think it rules everything. For the most part, I think guys generally fall somewhere in the middle. Personally, I’m probably right in the middle, even with my reverence for the work done in research and development.

“Data is a great tool if you’re open to using it. For the guys that don’t need it, that’s awesome. If you naturally have great shapes, that’s awesome. But I’ve found it very useful to use TrackMan and Edgertronic to fine tune the pitches I’m throwing. Everybody wants more hop on their fastball. Everybody wants more sweep on their sweeper. Everybody wants to throw really nasty stuff. So yeah, I would say I’ve been chasing movement profiles for a little while.”

Laurila: You threw some good sweepers today. Is that your best pitch?

Arrighetti: “I would say it’s my most confident pitch with a right-handed hitter in the box. And there is more to it than how much it moves. The point in space where the ball starts to move matters, as does having the ability to disguise your pitches. But while those things are important, for me, when it’s bigger it’s better. I typically look mostly at the actual amount of movement. Velocity as well, because I’m pretty good at spinning the ball. When I throw at a high spin rate, at high velo, I’m going to get big movement. That’s usually what I’m looking for.”

Laurila: What are the metrics on your sweeper?

Arrighetti: ““I get anywhere from 16 to 26 inches of sweep. I’ve actually gotten reps at 28, and while TrackMan is a little faulty sometimes with its setup, I like to believe that I’m capable of making it move that much. Today it was probably around 18 to 20. You also have to be able to adjust your lines with how much it’s moving. If I’m trying to throw it at a righty’s hip, I want 16, 18, 20. If I’m trying to throw it behind them, bigger than that. It will be closer to 78-79 [mph] when it’s big, and usually 80-82 when it’s smaller.”

Laurila: How do you go about adding or subtracting movement?

Arrighetti: “It’s very intent and leverage-based for me. If I find good leverage with the middle finger, which to me is… I don’t know if you’ve watched Matt Brash throw his, but he’s got one of the best sweepers in baseball. He tries to leverage the ball in his hand with a slight bias towards the side. I’ve found that doing that has helped me a lot. If I can find a seam, have that leverage, and feel the leverage at release, it’s going to be really good.”

Laurila: Do you feel that you comp to Brash?

Arrighetti: “No. If I were to comp myself on that pitch, I’m probably closer to Joe Ryan’s. In terms of sweepers that I love to watch and would like to model mine after, a guy in our org who does really great is Cristian Javier. His is the invisiball sometimes. It’s moving 20 inches with a little bit of induced vertical break at about 80 [mph].”

Laurila: How has your repertoire (four-seamer, sweeper, cutter, curveball, changeup) evolved since you signed?

Arrighetti: “I threw a pretty average four-seam, a really slow loopy curveball, a pretty fringe changeup, and a rifle slider. Really, the only one that’s similar now would be the rifle-spin pitch I throw, which I like to call a cutter.

“My changeup grip has probably changed the most. When I was in college it was a pretty standard circle that didn’t really complement the way I throw. I’m not very good at pronating, so I’ve shifted to more of a low-spin split changeup. I’ve seen a lot of progress with that, because I can keep the supinated wrist and pull through the ball a little bit harder from the top. I don’t really have to worry about turning it over much.”

Laurila: You mentioned spinning the ball well. Is that primarily with your breaking stuff?

Arrighetti: “I spin the fastball well, too. I’ve been up to 2,400 rpm, which is good post-sticky stuff crackdown. When guys were using stick, the really good ones were 2,800, 2,900, 3,000, which is unbelievable. I can spin a breaking ball 3,000, but I’ve never come close with a four-seam. My arm action is pretty whippy, which is usually good for spin rates.”

Laurila: Which of your breaking balls gets the most spin?

Arrighetti: “My curveball, which is more seam efficient than my sweeper. My sweeper is actually very not seam efficient. I’m trying to basically throw a two-seam the other way, if you will. Seam-shifted wake is a hot topic right now. It’s kind of hard to explain, but essentially, I don’t need spin efficiency or spin rate on the slider — but it helps it makes the ball appear white, which is useful.”

Laurila: Any final thoughts?

Arrighetti: “I’ve heard some guys throw around the term fake hop. That’s what we like to call induced vertical break hop. We kind of touched on this earlier. Looking at the TrackMan, my four-seam doesn’t have a lot of hop, but you have to look at the release height and the angle you’re throwing from. For a long time, I didn’t think my four-seam was anything special, and the Astros have made it really clear to me that it’s going to be a great weapon at the upper levels. That’s held true so far. Sometimes the data is a little tricky. You have to look at other numbers that maybe don’t jump off the page.”

Logan Webb was my pick for NL Cy Young last season, and while the prediction didn’t come to fruition, the San Francisco Giants right-hander did come close to capturing the honor — this despite an 11-13 record. (We’ve come a long way, haven’t we?) He finished second in the voting to Blake Snell, who is now his rotation mate, and while Webb’s major league-leading 216 innings certainly captured the attention of the electorate, many of his other numbers stood out as well. He ranked fourth among qualified National League pitchers in both ERA (3.25) and FIP (3.16), and his 1.29 walks per nine innings was second to none. Moreover, his 62.1% groundball rate was the highest in either league.

He hardly came out of nowhere. Webb was already good, as his stats over the past three seasons attest. Since the beginning of the 2021 campaign, he has a 3.07 ERA and a 3.00 FIP, and his signature sinker-changeup combination has been responsible for a 59.9% groundball rate. A comparably humble 23.1% strikeout rate over that span (21.4% last year) notwithstanding, the 27-year-old worm-killing workhorse is one of the best pitchers in the game.

Webb sat down to talk pitching at San Francisco’s spring training facility earlier this month. He’ll be on the mound later today when the Giants open the regular season in San Diego.

David Laurila: How have you evolved as a pitcher since coming to pro ball?

Logan Webb: “I’ve changed probably four different times. I was a sinker guy when I first started. Then I had Tommy John, and when I came back, so did the velo — it was back to the reason why I was drafted.”

Nolan Schanuel got to the big leagues in a hurry, and he wasted little time proving himself once he arrived. Called up less than six weeks after being drafted 11th overall last summer by the Los Angeles Angels out of Florida Atlantic University, the left-handed swinging first baseman hit safely in each of his first 10 games. Moreover, he reached base in all 29 games he appeared in and finished with a .402 OBP. Indicative of his calling cards — plus plate discipline and quality bat-to-ball skills — he drew 20 walks and fanned just 19 times in 132 plate appearances.

The one knock on his game is he doesn’t hit for much power. Schanuel homered just twice after reaching pro ball — once each in Double-A and the majors — and while that profile isn’t expected to change markedly, he did leave the yard 19 times in his final collegiate season. At 6-foot-4, 220 pounds, he also possesses the frame to become more of a long-ball threat as he further acclimates to big-league pitching. Just 22 years old (as of last month), he has plenty of time left to grow his game.

Schanuel talked hitting at the Angels’ Arizona spring training complex earlier this month.

David Laurila: It’s not uncommon for modern day players to identify as hitting nerds. In your opinion, what constitutes a hitting nerd?

Nolan Schanuel: “There are so many ways you can put it. I think it’s somebody that studies not only their own swing, but also other people’s swings, seeing what works for them. Growing up, I looked into dozens of swings. Barry Bonds, Ichiro [Suzuki] — seeing what works for them and kind of trying to put it into mine. So, I would say that being a hitting nerd is studying other people and kind of inserting some of what they do into themselves.”

Laurila: You just named two hitters with very different swings. Were you ever trying to emulate either of them?

Schanuel: “I wouldn’t say emulate. I would say that I tried to pick out pieces of what they did really well. I didn’t really know my swing when I was first doing this, so putting things into it kind of made it what it is today.”

Laurila: What did you take from Ichiro? Read the rest of this entry »

When Eric Longenhagen and Tess Taruskin blurbed Ben Brown in last month’s Names To Know: 100 More Relevant Prospects feature, they noted his “monster mid-90s fastball/breaking ball combo.” Power is the defining characteristic of Brown’s arsenal. The 24-year-old righty ranks among the top pitching prospects in the Chicago Cubs organization, and following an impressive in spring training, he is expected to make his big league debut in the forthcoming campaign.

Brown began coming into his own in 2022 — the year he was acquired by the Cubs from the Philadelphia Phillies in exchange for David Robertson — and he made further strides last year. Across 92.2 innings between Double-A Tennessee and Triple-A Iowa, the 6-foot-6 righty logged a 12.6 strikeout rate while holding opposing hitters to a .215 batting average. His command faltered at times — a health-related speed bump was a contributing factor — but the power remained a constant.

Brown discussed his repertoire and approach at the Cubs’ spring training facility in Mesa, Arizona last week.

———

David Laurila: You consider yourself a pitching nerd. How did that come about?

Ben Brown: “I’ve been one my entire life. I was coached really well growing up, but I also loved to watch YouTube videos of guys throwing. Roy Halladay. Josh Beckett. I was a big Red Sox fan, so I watched Beckett, Jon Lester, Daniel Bard, [Jonathan] Papelbon. I picked up a lot from that.

“I also spent some time at Driveline after I had Tommy John surgery [in 2019], and got introduced to that whole community in Seattle. I can be the hardest critic on myself, because I know what looks good, as well as the numbers you aspire for analytically. I feel like I’m pretty well versed on all that. And I’ve definitely had a lot of really good discussions with pitching coordinators and whatnot about analytics since getting traded over to the Cubs.”

Tarik Skubal is slated to take the mound for the Detroit Tigers on Opening Day when the season begins three weeks from Thursday. Four years into his big league career, the 27-year-old southpaw is emerging as one of the top left-handed starters in baseball. After missing the first three months of last season recovering from flexor tendon surgery, he was one of the best pitchers in baseball upon making his season debut, on July 4. Skubal fashioned a 2.80 ERA, a 2.00 FIP, and a 32.9% strikeout rate — as well as a stingy 4.5% walk rate and a .199 BAA — in 15 starts comprising 80 1/3 innings. His 3.3 WAR from July through the end of the season led all pitchers in that span. And there is reason to believe that he is still getting better, as he adds fastball velocity — he’s hit 99 mph this spring, up from his average of 95.8 mph last season — and fine tunes his five-pitch arsenal.

Skubal sat down to talk pitching at the Tigers’ spring training facility in Lakeland, Florida last week.

———

David Laurila: Looking at your numbers, I saw that your ground ball rate (51.6% last year) keeps getting higher and higher, and your walk rate keeps getting lower and lower. How have you made those things happen?

Tarik Skubal: “I think it all kind of just stems from confidence and the complete arsenal. When you can throw five pitches over the plate, in the zone, and just go right after guys, you tend to get more uncomfortable at-bats. If you can throw different pitches in different counts, hitters have to be a little bit defensive and aren’t getting their A swings off as often. That’s kind of my approach, and I think it impacts the results I’m getting.”

Laurila: That makes sense, as you don’t throw a lot of sinkers… Read the rest of this entry »

Zack Wheeler has arguably been the best pitcher in baseball over the past four seasons. Since joining the Philadelphia Phillies prior to the truncated 2020 campaign, the 33-year-old right-hander has made 101 starts and boasts a 3.06 ERA, a 2.90 FIP, and a 26.7% strikeout rate. Moreover, his 19.3 WAR over that span is tops among his contemporaries.

A thirst to continually get better has helped bring Wheeler to the pinnacle of his profession. Never entirely satisfied with the depth and quality of his arsenal, he’s always looking for a new edge, whether it’s an additional weapon or an upgrade to one already in his toolbox. Just last year he added a sweeper, and opposing hitters can expect to see yet another option when he takes the mound in 2024.

Wheeler discussed his growth as a pitcher, as well as his goals going forward, last week at the Phillies’ spring training complex in Clearwater.

———

David Laurila: How have you evolved as a pitcher over the years?

Zack Wheeler: “I’ve developed more pitches since I got drafted. Everything has gotten crisper. After my TJ [in 2015], I was able to gain some command, which I didn’t have before. So pairing the repertoire with command took me to that next level. Really, a lot of it has just been repetition and learning, and from there putting it all together.” Read the rest of this entry »

To understand why Baltimore Orioles shortstop Jackson Holliday is the no. 1 prospect on our Top 100 list, look no further than Eric Longenhagen and Tess Taruskin’s writeup of the 20-year-old phenom. They describe Holliday, the first overall pick in the 2022 draft, as “a sweet-swinging shortstop with above-average feel for contact and burgeoning power,” and close their evaluation by predicting that he “is very likely to become a 5-WAR shortstop who does everything well.” He has been spending time at second base this spring, because the O’s already have last year’s no. 1 overall prospect Gunnar Henderson at shortstop, but either way, stardom is seemingly in Holliday’s future.

That the promising youngster is the son of former big league slugger Matt Holliday is well known. It is also a primary factor in his advanced approach to hitting, as well as his overall understanding of his craft. Last season, which he began in Low-A and ended in Triple-A, the lefty-hitting Holliday produced a .323/.442/.499 slash line and 159 wRC+ across four levels of the minor leagues.

Holliday sat down to talk hitting over the weekend prior to a Grapefruit League game in Sarasota.

———

David Laurila: How do you approach hitting?

Jackson Holliday: “As far as guessing pitches… that’s not something I’m great at. But I really enjoy learning about swings — different guys’ swings — how they work, and little things that can help, like cues. My dad has been around baseball for so long, and is such a hitting guy, and I got that from him. But yeah, my approach is pretty simple. I try to stay in the middle of field, stay on my backside, and hit the heater.”

Laurila: Are you basically hunting fastballs and adjusting from there?

Holliday: “Yeah. I sit fastball. I don’t sit offspeed unless there is a real outlier. That’s something I learned from my dad. He would sit heater and try to hit it to the middle of the field. If you’re in a good spot to hit a fastball to the middle of the field you can adjust to the offspeed pitch a lot better than you can sitting offspeed and trying to hit a heater.”

Laurila: How hard is it to be diligent with that? There are going to be times where your subconscious brain tells you, “He’s not going to throw a fastball here.” Read the rest of this entry »

Kyle Teel is well positioned as Boston’s catcher of the future. Drafted 14th overall by the Red Sox out of the University of Virginia last summer, the backstop, who turned 22 last week, enters his first full professional season as the fifth-ranked prospect in Boston’s farm system and no. 80 on our Top 100. According to our lead prospect analyst Eric Longenhagen, Teel “presents a well-rounded overall profile” that includes “a fabulous offensive résumé.”

His 2023 numbers were certainly exemplary. Teel slashed .407/.475/.655 with 13 home runs in his junior year at UVA, helping earn him first-team All-American accolades and rocketing him up draft boards. Upon reaching pro ball, his left-handed stroke produced a .363/.483/.495 slash line and a 173 wRC+ in 114 plate appearances across three minor league levels, his last stop being Double-A Portland.

Defense is, of course, a major responsibility for catchers. Last month, when Teel was at Fenway Park for Boston’s rookie development program, I spoke with him about his preparation and setup behind the plate, his throwing, and his offensive profile.

———

David Laurila: Catching is a science as well as an art. With that in mind, what role does data play in what you do defensively?

Kyle Teel: “I really like data when it comes to how pitchers’ stuff moves, and heat maps on what to throw to certain guys at certain times. That’s obviously beneficial, but there is also nothing like the feel of the game. You need to be using your eyes and seeing what you can take in, in the moment. But the data is definitely important. Before every game, I look at what pitchers like to throw, their tendencies in certain counts, and things like that. That’s both as a catcher and when I’m hitting.”

Laurila: Do you think like a catcher when you’re in the batter’s box?

Teel: “I kind of do. There are benefits to doing that, just knowing how pitchers work and what guys tend to throw in certain counts. Overall, I would say that having a good feel at the plate and calling pitches is very similar.”

Laurila: How do you balance data and instincts? Read the rest of this entry »

Rhett Lowder has yet to pitch in a professional game, but already he ranks not only as the top pitching prospect in the Reds system, but also as the no. 44 player on our Top 100 list. Remarkably, that’s not all that surprising. Selected seventh overall by the Reds out of Wake Forest University, the 21-year-old right-hander will make his pro debut on the heels of a spectacular junior campaign that saw him go 15-0 with a 1.87 ERA and a school record 142 strikeouts. The Atlantic Coast Conference’s Player of the Year for the second straight season — he’d gone 11-3 with a 3.08 ERA in 2022 — Lowder seems a lock to pitch in the middle of a big league rotation. Moreover, his arrival in Cincinnati should come in the not-too-distant future.

In terms of style, the native North Carolinian might best be described as a technician with multiple above-average offerings. Lowder’s repertoire comprises two- and four-seam fastballs, a slider, and a changeup, and he augments that arsenal with plus command and a feel for his craft that belies his level of experience. Mixing and matching is one of his strong suits, giving him an opportunity to navigate lineups deep into games.

———

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

Rhett Lowder: “A little bit of both. In the offseason you can probably get into more of the science side of it, breaking yourself down. But during the season it’s more of an art; there are a bunch of different ways to to get the job done. Plus, everybody is unique. There is no cookie-cutter way to get outs.”

Laurila: Some of what I’ve read about you suggests craftsman, but are you actually more of a power guy?

Lowder: “I think it just really depends on the game. One of my stronger suits is that I can adjust based on the opponent, and on some days you have more overpowering stuff than you do on others. I can kind of be like a chameleon and change based on the environment and the game I’m in. I’m not necessarily the same exact guy every single time I go out there.

“There are some things I fall back on more times than not when I get into trouble, but going into most games, it really just depends on the [opponent]. I try to overlay my strengths over the other team’s weaknesses and kind of see where that leads me. I try to be able to adapt as quickly as possible.”

The Tampa Bay Rays farm system has been consistently robust over the past half dozen seasons, and while it is no longer ranked first or second, it remains top notch. Currently populated with the likes of Junior Caminero, Carson Williams, Curtis Mead, and Xavier Isaac, it contains a number of high-ceiling players projected to contribute at the big league level, some as soon as this year. That is especially the case for some of the position players, especially Caminero, who debuted in the big leagues last September and is one of baseball’s best prospects.

Blake Butera is as well versed on Tampa Bay’s pipeline as anyone. Promoted to Senior Director Player Development at the conclusion of the 2023 campaign, he has worked in the system as a minor league coach, manager, and field coordinator since 2017. In each of his prior positions, he’s had a hands-on role with the development of the players he now oversees.

———

David Laurila: I asked you about Junior Caminero when we spoke in December 2022. Outside of gaining more experience, what has changed with him since that time?

Blake Butera: “Honestly, not much. If I had to pick one thing, I would say it’s his defense. He’s made a concerted effort to get better at third base, and also shortstop, which gives him the opportunity to play shortstop if needed. Which it could be. He’s still learning the third base position. He hasn’t played a ton there; he played more shortstop when he was younger, and then we put him at third base predominantly last year. He’s really focused on his defense — first-step quickness, reading the hops at third, getting used to the different angles.

“Offensively, it’s more so just being a little bit more patient at the plate and going to get pitches that he can drive versus trying to hit everything. To be honest, he can hit everything, which is why he’s been swinging at a lot of different pitches.” Read the rest of this entry »
