Grayson Rodriguez is a top-100 prospect thanks to a four-pitch mix that includes an explosive high-spin heater. As electric as that mid-90s offering is, it’s not the most eye-catching item in his arsenal. The Orioles’ top pitching prospect throws a changeup with screwball characteristics. While not technically a screwball — Juan Marichal and Mike Norris come to mind — the movement profile is anything but run-of-the-mill for a right-handed change. At age 21 with a bright future ahead of him, Rodriguez is armed with a unique pitch.

David Laurila: You’ve developed a good changeup. What makes it effective?

Grayson Rodriguez: “The way I like to attack with my fastball sets up my changeup well, how it moves and what it looks like out of my hand. As I’ve learned how to throw it with TrackMan and Edgertronic cameras, I’ve figured out a way to get the ball to spin exactly how I want it to. Those things have really helped me, because my changeup is different from a lot of other guys’. It’s almost like a screwball. Hitters don’t see it as much as they do a normal changeup.”

Laurila: How do you get the screwball action?

Rodriguez: “At my release point, my wrist is pronating a lot more than normal. If you break down my hand movement and wrist position — break everything down in slow motion — it’s really turning over. It’s kind of an aggressive, violent turn-over. You don’t see that very often. My ball, on an axis, is spinning at about 3 o’clock to 3:30. If you were to picture that on a clock, it’s almost like a left-handed slider, or a left-handed curveball.” Read the rest of this entry »

Jonathan Schoop slashed .169/.217/.273 last year in counts that included two strikes, and over his career that line is an equally-squeamish .162/.208/.276. The Detroit Tigers infielder — recently re-signed to a one-year deal worth a reported $4.5M — isn’t alone in scuffling when a possible punch-out looms. Across the two leagues, batters slashed .167/.248/.275 in those situations in 2020

Schoop typically doesn’t get into two-strike counts by taking pitcher’s pitches and patiently waiting for mistakes. Restraint has never been his forte. Since debuting with the Baltimore Orioles in September 2013, Schoop’s walk rate is a lowly 3.8%, while his Swing% and O-Swing% both rank toward the top of our Plate Discipline leaderboard. And while toning down that level of aggression is a goal, it’s not as though a Tiger can simply change his stripes. Schoop isn’t about to morph into Joey Votto — not at age 29 — which means a different two-strike approach might be in order.

I asked Schoop about that during a Zoom call earlier this week.

“I’ve got to do better with two strikes,” admitted Schoop, whose 22% K-rate last year was a shade under his career mark of 22.9%. “I need to put the ball more in play and see what happens. I’m going to change that. I’m going to be better at everything. The things I need to be better in, I’m going to be better in. The things I’m good in, I’m trying to be a tick better on them, too.”

Following up, I asked Schoop if he’s considered shortening his swing with two strikes, maybe even choking up on the bat. While that might mean giving up some power, it would likely help him boost his contact rate. Read the rest of this entry »

Josh Staumont has intriguing StatCast numbers. The 27-year-old Royals right-hander ranks in the 99th percentile for fastball velocity, and his curveball is 91st percentile in spin rate. That combination helped produce a 2.45 ERA and 37 strikeouts over 25.2 relief innings last year. A former second-second pick whose command issues have dogged his development path, Staumont allowed just 20 hits but walked 16 batters.

There’s another metric on Staumont’s Statcast page that jumps out just as much as his velocity and spin. When the Azusa Pacific University product didn’t miss bats, the results tended to be loud. Somewhat remarkably, given that he had a solid season overall, Staumont was 2nd percentile in hard-hit rate — not second best, but rather second worst among his contemporaries.

Staumont addressed that conundrum, as well as his high-profile arsenal and his love-hate relationship with pitching analytics, over the phone last week.

David Laurila: Looking at your Statcast numbers, I see elite velocity and a lot of spin. What do those things mean to you?

Josh Staumont: “Looking at the metrics of baseball… it’s kind of a fickle theme. You see all these numbers, and some of them are leaning toward more consistency. Others are a little atypical. Personally, I see it more as an effort-based system. That kind of goes hand-in-hand with how baseball is progressing. I believe the floor is getting raised a little when it comes to the talent threshold, with all the access to data, the access to training, and things like that. Analytically, I think the focus on numbers has allowed for progression based off of numbers. Read the rest of this entry »

Garrett Richards has an uncanny ability to spin a baseball. Per Statcast, the 32-year-old right-hander — recently signed to a free-agent contract by the Boston Red Sox — was 99th percentile in curveball spin last year, while his four-seam spin ranked in the 97th percentile. Moreover, the most-effective weapon in his arsenal, a 2,746-RPM slider, was topped only by Sergio Romo’s 2,913 RPMs among hurlers who threw the pitch at least 200 times.

Richards’s least-effective offering in 2020 was a two-seamer that’s hard to put a positive spin on. The erstwhile San Diego Padre threw 66 of them, and the ones that were put into play tended to get punished. Opposing hitters whacked them to a tune of a .467 batting average and an .867 slugging percentage. And it was even worse in 2019. While a 28-pitch sample obviously needs to be taken with a huge grain of salt, numbers like .500 and .875 stand out like a sore thumb. I asked Richards about his plans going forward, anticipating that the pitch might be going into mothballs.

Au contraire.

“It’s definitely not a pitch that I’m not going to throw,” said Richards. “I’ve always been able to cut the ball to both sides of the plate, but it’s nice to have something moving in the other direction. I need to get it back to sinking, or even having some more arm-side run. Come spring training, I’ll be back on the mound, trying to figure it out.” Read the rest of this entry »

Jeter Downs can swing it. As Eric Longenhgan wrote last month, the top prospect in the Boston Red Sox organization “has been a polished, advanced-for-his-age hitter dating back to high school.” That attribute led to Downs being drafted 32nd overall by the Cincinnati Reds in 2017, and subsequently included in a pair of major trades. In December 2018, he went to the Los Angeles Dodgers as part of a seven-player swap that included Matt Kemp, Yasiel Puig and Alex Wood, and 12 months ago he came to Boston as part of the Mookie Betts deal. A 22-year-old second baseman who finished 2019 in Double-A, Downs projects, per Longenhgan, as an everyday player at the major-league level.

David Laurila: Let’s start with a self scouting report: How would you describe yourself as a hitter?

Jeter Downs: “I like to think of myself as a contact-first guy. I’m not the biggest guy in the world — I’m 5-foot-11 and usually between 185 and 188 [pounds] — so I don’t try to hit for power. That’s something that comes naturally, from having the right approach. I call home runs ‘a mistake,’ honestly. You don’t try to hit home runs; they just happen. Basically, I just try to get in good counts and swing at good pitches.”

Laurila: How would you describe your swing?

Downs: “If you go by numbers and results, they would show that I’m more of a loft guy. But at the end of the day, I just try to put a nice level swing on the ball and hit it hard. I’m not trying to hit the ball in the air. I’m just trying to hit nice line drives everywhere.”

Laurila: Eric Longenhagen wrote that you punish pitches down in the zone, but that you could be susceptible to getting tied up by velocity in on your hands. Do you agree with that? Read the rest of this entry »

Quinn Priester has gained a lot of helium since ranking seventh on our 2020 Pittsburgh Pirates Top Prospects list. Thanks to stellar showings at the alternate camp and instructs, the 6-foot-3, 215 pound right-hander has climbed into the middle of Baseball America’s and MLB Pipeline’s Top 100s. (Our 2021 Pirates offseason list hasn’t run yet, but according to Eric Longenhagen, Priester will feature prominently and will grace this year’s Top 100.) Just yesterday, Jim Callis wrote that some scouts have told him that Priester — the 18th overall pick in the 2019 draft — could emerge as the best pitching prospect in baseball in 2021.

Priester, who’ll celebrate his 21st birthday this coming September, was featured here at FanGraphs 12 months ago. Last week, he caught us up with the strides he’s made since that time.

David Laurila: You were at the alternate site last summer. What was that experience like?

Quinn Priester: “It was about two weeks, so it wasn’t a whole lot of time, but it was super big for me. I got to be around older guys, some who have been in the big leagues, that have experienced things I haven’t. I’ve only had half a season with two short-season teams — I haven’t come close to a minor-league season of 144 games — so I’m behind the learning curve in that respect.”

Laurila: What can you learn from being around more experienced players?

Priester: “Just the way they prepare. They have intent with every throw, because they know how valuable those throws are over the course of the season. Wasting throws is going to lead to more soreness, and stuff like that. It was cool to literally see how to play catch again, and not just be the high school kid who throws really hard. It was about getting in the work that I need to get in, like staying behind fastballs and making the most out of the couple of curveballs I’ll throw in catch play. Rather than just throwing, I was having direction and a goal. Read the rest of this entry »

Casey Mize plans to be a different pitcher in 2021. Not just in terms of results — the rookie right-hander had a 6.99 ERA and a 6.47 FIP in seven starts with the Detroit Tigers last year — but also with how he employs his arsenal. Not surprisingly, data will be playing a role. Mize has a history with pitch design that dates back to his days at Auburn, and those efforts have only increased in pro ball.

I asked the first-overall pick in the 2018 draft what technology has taught him about his pitches, and how it’s shaping his efforts to improve.

“It’s pretty much a horizontal profile,” Mize responded. “We’re starting to take the four-seamer up a little bit to add a little more vertical, because it played so well last year. My splitter is super vertical, and we’re trying to really maximize that, because my slider has more of a horizontal break.”

Mize acknowledged that his two-seamer profiles as horizontal as well, getting more arm-side run than depth. It’s a pitch he’s favored, but that’s one of the changes currently in the works. The 23-year-old hurler not only plans to elevate more four-seamers, he intends to up its overall usage. His two-seamer will be used primarily “to mask the splitter,” a pitch he likes to have diving below the zone. Read the rest of this entry »

The Texas Rangers brought a promising young hitter on board when they took Justin Foscue with the 14th-overall pick of last summer’s draft. A 21-year-old second baseman, Foscue put up a .958 OPS in his sophomore season at Mississippi State University, and he followed that up by slashing 321/.464/.509 in last year’s truncated collegiate campaign. Moreover, he displayed exemplary plate discipline and bat-to-ball skills. Foscue had 69 plate appearances with the Bulldogs in 2020, and drew 15 walks while striking out just three times.

What kind of hitter does the Huntsville, Alabama native view himself as, and how might that change as he advances through the professional ranks? Foscue addressed those questions, and much more, over the phone earlier this week.

———

David Laurila: How would you describe your hitting approach?

Justin Foscue: “That goes into what your strengths are as a hitter. For the past two years — my sophomore and junior years — I was really keyed in on advantage counts. On 1-0, 2-0, 3-1, I was sitting on a middle, middle-in, fastball, and if it was there I was trying to hit it out of the ballpark. If it wasn’t there, I wasn’t swinging. In those advantage counts, you’ve still got more pitches to play with.

“As a hitter, you have to be very disciplined with your approach, because if you don’t stick to it, you’re not going to be as successful as you could be. I kind of just try to hit mistakes. I’m also sitting fastball, because when guys are throwing 94 to 98 [mph], you’ve got to be keyed in on that or you’re going to miss it. And if he hangs a breaking ball, you have to be ready for that, too. One reason I’ve been so successful is that I haven’t missed too many pitches that I should be hitting.”

Laurila: What about when you’re not in an advantage count? Read the rest of this entry »

When Eric Longnhagen wrote up Daulton Jefferies for last year’s Oakland A’s Top Prospects list, he cited a “plus, upper-80s changeup and plus command” as the now–25-year-old right-hander’s primary attributes. That combination helped earn Jefferies a cup of big-league coffee last September, and it has him projected as a member of Oakland’s starting rotation for the upcoming season.

Drafted 37th overall out of Cal-Berkley in 2016 — he underwent Tommy John surgery that same year — Jefferies is atypical among young, modern-day pitchers in that he stands just six-foot (and weighs 195 pounds) and is neither data-savvy nor a flamethrower. His fastball sits a relatively pedestrian 93–95 mph, and the spin rates on his array of pitches remain a mystery to him. Then there is the strangest thing of all: Jefferies features a no-seam repertoire.

———

David Laurila: What is your full repertoire, and what is your best pitch?

Daulton Jefferies: “I have four- and two-seam fastballs, a changeup, a slider, and a cutter. My best pitch is my changeup.”

Laurila: What makes it effective?

Jefferies: “I think it’s more of a tunneling thing. You want everything to look like a fastball for as long as possible — Gerrit Cole does that really well, [Jacob] deGrom, [Max] Scherzer, all those guys — and mine has good depth. It’s also really hard; it’s like 87 to 90 [mph] and I can run it up to 90 at times. The only time I get in trouble is when it flattens out and basically becomes a straight fastball. Most of the time, it’s my go-to pitch, right-on-right. It’s my baby.” Read the rest of this entry »

Mitch Keller has only thrown 69-and-a-third big-league innings, and he’s already had a remarkable career. The baseball gods are a big reason why. In his 2019 rookie season, the now-24-year-old Pittsburgh Pirates right-hander had a 7.13 ERA to go with a 3.19 FIP, and this past season he had a 2.91 ERA to go with a 6.75 FIP.

Hello, BABIP.

In an almost-inexplicable quirk of fate, Keller followed up a .475 BABIP — the highest one-season mark in MLB history — with a .104 BABIP in 2020. No pitcher who threw 20-or-more innings in last year’s pandemic-truncated campaign had a smaller percentage of balls put in play against him fall safely to the turf. This happened with an average exit velocity of 88.5 mph, which was higher than the 87.6 he’d allowed in 2019.

Ben Lindbergh wrote about Keller’s snake-bit season for The Ringer last spring, and the conversation they had prior to publication is what brought the data to the fore.

“I remember getting off that phone call and looking it up myself,” said Keller. “I was like, ‘Oh, my goodness. That’s crazy.’ I knew that I had a high BABIP, but I had no idea it was the highest in history. Once he told me, it wasn’t like I was coming back to the dugout thinking, ‘Man, I think I’m having some bad luck.’ It was actually on paper, as a stat. It was, ‘No, seriously. I was having bad luck.” Read the rest of this entry »
