I’ll warn you up front: this article is going to be a loose description of some research I’m working on, plus a copious amount of rambling. I’ve been looking for non-handedness platoon effects a lot recently. Partially, it’s because they’re fun to look at. It’s also because the Giants seem to be using some non-handedness platoons to good effect this year — they’re certainly doing more than just picking left or right based on the opposing pitcher.

I haven’t finished exploring this one yet. So why write an article about it? People like to read articles — but also, I get a lot of good ideas from reading the comments (this being perhaps the only site on the internet where that’s a reasonable sentence) and I could use some inspiration in terms of more things to do here. Without further ado, let’s talk inside/outside splits.

Listen to a game, and you can’t miss it. Announcers will tell you that some players are adept at taking an outside pitch and hitting it the other way, or turning on anything inside and giving fans some souvenirs. I split the plate into thirds, then used those thirds to define three zones: anything on the inside third or off the plate inside is “inside,” anything on the outside third or off the plate outside is “outside,” and the rest is the middle.

Here’s something right off the top: Bryce Harper has destroyed inside pitches this year. He’s seen 441 of them and produced 22 runs above average. That counts good takes as well as solid contact, but his batting line is spectacular, too — .367/.480/.735, good for a .497 wOBA. Give him something he can pull, and it’s all over but the crying.

If you can manage to stay on the outer third, you have a better shot. He’s seen 864 pitches out there (pitchers aren’t dummies) and produced 9.2 runs above average, a far lesser line. That’s still solid — he’s an MVP candidate — but it’s nowhere near the scorched-earth stuff he manages on inside pitches. Read the rest of this entry »

With the elimination of the waiver deadline, the last two months of the season (or more accurately now, the last six weeks) can leave front office personnel feeling like little more than helpless observers. Problems at the big league level, whether of the health or performance variety, are going to pop up, but for the most part, the answers to those problems have to come from within. Yes, there’s the occasional player who gets designated for assignment who deserves consideration, but otherwise teams will either lean on the depth they’ve spent much of the year trying to establish or curse the risks they took in terms of depth in order to improve their big league roster. Here are the depth situations for the American League playoff contenders, with the National League to follow tomorrow.

American League East

Tampa Bay Rays
Strengths: The Rays bolt together pitching staffs as well as any team in baseball, and there are plenty more pieces available to them at Triple-A Durham should the need arise. They load up on pitch-data darlings while also developing plenty from within, and the result has been the best record in the International League, with their staff generating a team-wide strikeout rate of over 28%. With five current Durham pitchers already on the 40-man roster, managing innings down the stretch shouldn’t be an issue, be it for need or just for the purposes of keeping players fresh. In terms of position players, Vidal Bruján continues to slot in all over the diamond; his ability to play six positions makes him the most likely hitter to be called up.

The Learning and Developing a Pitch series returned in June after being on hiatus last season due to the pandemic. Each week, we’ll hear from three pitchers on a notable weapon in their arsenal. Today’s installment features Andrew Kittredge, Matt Manning, and Tyler Wells each discussing their slider.

Andrew Kittredge, Tampa Bay Rays

“It was after my freshman year of college, playing summer ball in Newport, Rhode Island. I actually started off calling it a cutter. It was pretty small, and it was firm. I was throwing my fastball anywhere from 90 to 94 [mph] and the cutter was around 89-91. Slowly, over time, I started getting around it a little bit more, and it got bigger and slower. By the time I got into pro ball, it was probably 83-85.

“It was a pretty good pitch for me — I had a good feel for it — and that’s kind of what I had up until 2019. Then I started throwing it harder again. I didn’t really change the grip, or my mindset, as much as I … well, the mindset was to try to stay behind it a little longer and accelerate through it at the end with hand speed. So while the velocity kind of jumped, I didn’t really plan on it doing that. The idea just was to try to tighten up the spin, and with the increased spin I added velocity. I also made it a little shorter; it’s not as big as it used to be. Read the rest of this entry »

Sinkers (or two-seamers, as they’re also called), are a mixed bag. Maybe it’s just me, but they seem to produce polarizing results. They’re used by the most mediocre of control artists and the league’s best pitchers alike. They’re responsible for some of the slowest as well as the fastest, well, fastballs – just watch teammates Adam Wainwright and Jordan Hicks. When a pitcher lobs a bad sinker, hard contact seems inevitable. But when a good sinker is dangled as bait and the hitter bites, there’s no escaping that darn infield.

Extremes can work. They’re also risky, which is why the average pitcher relies on a four-seam fastball. We know what makes that pitch tick, and it slots into any arsenal. Sinkers are trickier to tame, which helps explain why pitchers have shied away from them in recent years. But as I explored earlier this year, a decline in usage does not equal a decline in relevance. If anything, the emphasis on seam-shifted wake has piqued the sabermetric community’s interest in sinkers.

When I wrote the article I referenced above, I was left with a few unanswered questions. For example:

“That being said, I’m not sure if higher sinker velocity correlates to better results, whether that be in terms of wOBA or Run Value… [a]t a glance, there’s no significant relationship between sinker velocity and xwOBA allowed (r^2 = 0.04).”

Immediately, there’s a flaw within that finding. I’d measured the relationship using pitchers who threw sinkers, not the sinkers themselves. It’s possible a pitcher possesses the makings of a good sinker but struggles with command. This time, I got down to business. I had pitch data from the 2018-19 seasons from an earlier project, so that became my sample. One caveat, though: I only included sinkers that resulted in batted balls. For the most part, the intended purpose of a sinker is to generate soft contact, and I felt including whiffs, fouls, and other results would produce murkier conclusions.

Justin Yurchak is flying under the radar as a prospect. He’s flying high in present-season performance. Unranked on our 2021 Los Angeles Dodgers Top Prospects list, the 24-year-old first baseman boasts the highest batting average among minor-league hitters with at least 260 plate appearances. Currently with Double-A Tulsa after spending the first three months of the season with High-A Great Lakes, Yurchak has come to the plate 322 times and is slashing a stand-up-and-take-notice .365/.452/.498.

Those numbers aren’t as nearly surprising as you might think. Since entering pro ball in 2017 as a 12th-round draft pick out of SUNY-Binghamton, Yurchak has put up a sumptuous .318/.413/.468 slash line. With the exception of a pedestrian year in 2018 — a 100 wRC+ in Low-A — he’s always hit.

I asked Yurchak about that lone blemish on his otherwise stellar stat sheet.

“That year, I got off on a bad track and had a hard time figuring out what was wrong,” Yurchak told me on the final Friday of July. “There was a little bit too much movement in my lower half. Part of it was that I wasn’t gathering my legs under my body. When I was landing in my load, there was a little bit of a slide with my hips, and my bat was dragging. Had I been able to make [the needed] adjustment earlier, I think the season would have gone differently for me.” Read the rest of this entry »

Here’s a story that you hear all too often these days. A reliever has a breakout season, perhaps aided by leaning more into throwing his best pitch to the exclusion of everything else. He parlays that into an offseason deal, or maybe a newly-prominent role on his current team. Then the next season starts, and the bloom is off the rose. Whatever ineffable magic powered last season is simply gone.

Here’s another story you hear all too often these days. A reliever has a bad stretch, looks like he might be cooked. The Rays, though, have seen something in him. They trade for him, whisper a few sweet nothings (or, fine, mechanical adjustments) into his ear, and bam! He’s part of their bullpen army.

Here’s the fun part: Matt Wisler personifies both of these stories. He was so bad the Giants designated him for assignment after a horrid start, then agreed to a trade with the Rays. Since heading East, he’s been incredible, one of the best relievers in the game. Seriously, look at these splits:

I had to know what changed. I’ll warn you: there’s a lot of failure in this article, a lot of finding not much, before we get to the good stuff — and I promise there’s good stuff. If you’re not into seeing how a pitcher can get to wildly different results with a substantially similar process, this article might bore you. But if you’re curious like I was, read on, and delve deeply with me into the minutiae of a pitcher who didn’t change very much and yet went from unplayable to great. Read the rest of this entry »

This series of articles looks at players whose careers are cut short due to misfortune, but few of them are cases as sudden or as dramatic as that of former Astros pitcher J.R. Richard, who died one week ago at age 70. The Houston fireballer had emerged as one of the game’s hardest throwing starters and a potential ace when he suffered a stroke 41 years ago and collapsed during the team’s pregame warmups. He never pitched in the majors again.

Richard’s debut was about as brilliant as one can get: a complete-game shutout of the Giants in September 1971 in which he struck out 15 batters. This was toward the end of Willie Mays‘ illustrious career, but how many pitchers can claim to have pulled off a hat trick of whiffs against an inner-circle Hall of Famer in their debut? Those 15 strikeouts tied pitcher Karl Spooner’s debut record; incidentally, Spooner is another player with a short career that was ended by a shoulder injury a year later, but that’s a tale for another time.

As a pitcher, Richard looks more at home in 2021 than in 1970. At 6’8″ with a fastball hitting the century mark and a slider in the low 90s, there was a lot of intimidation and little in the way of pitching to contact here. The only problem was that he was raw mechanically, just two years out of high school, and coaching staffs weren’t as experienced as today at helping pitchers harness such an explosive repertoire; over his 12 remaining innings that season, including a first inning he didn’t finish, Richard walked 13 batters.

The wildness never quite went away, and Richard spent the new few years riding the Triple-A shuttle. But the Astros traded Claude Osteen in 1974 for two recent Cardinals draft picks, and Don Wilson and his son died in January 1975 from carbon monoxide poisoning, and these were the days you couldn’t just go shopping in free agency. So up to the majors came Richard for good.

Don Mattingly knows hitting. The Miami Marlins manager slashed .307/.358/.471 over his 14 seasons with the New York Yankees, winning a batting title along the way. Since his playing days, he’s served as a hitting coach for both his former team and for the Los Angeles Dodgers. “Donnie Baseball” also managed the Dodgers, a five-season stint that preceded his arrival in Miami six years ago.

Mattingly shared his thoughts on hitting, both mechanical and philosophical, over the phone prior to a recent game. (This interview was edited for length and clarity.)

———

David Laurila: Let’s start with your playing career. How would you describe who you were as a hitter?

Don Mattingly: “I kind of changed over the years. I came up as a guy who was probably known more for just putting the ball in play. I hit for [a high] average in the minor leagues. I used the whole field and had more of a hit-it-where-it’s-pitched type approach. From there, I kind of grew in strength, which allowed me to drive in runs. I became more of a doubles guy.”

Laurila: Was the change mostly a matter of getting stronger, or were there adjustments, as well?

Mattingly: “I definitely made adjustments. The biggest was probably getting physically stronger — that was the start of it — [because] I didn’t really hit for true home run power. I didn’t have home run power through the minor leagues. Read the rest of this entry »

As a shortstop, you never want to be in this position:

You can almost see the expletives flying out of his mouth, and it gets worse: Nolan Arenado is out of frame to the right, which means that ball is ticketed for left field. How did it get to this point? Let’s back up.

When you’re fielding a bunt, decisions come at you immediately. Barehand it? Glove it? Lead runner? Take a beat and take the sure out? You have to make all of those choices in a split second. Here’s the play in the ninth inning of Sunday’s Cardinals/Royals game that left Paul DeJong lunging helplessly:

Obviously, it didn’t turn out well. But it’s not as though Paul Goldschmidt didn’t know there was a chance of failure going in. Going for the lead runner on a bunt is a high-risk, high-reward play; anyone could tell you that. How large was the risk? How valuable was the reward? Let’s find out together, because I think this situation is low-key fascinating. Read the rest of this entry »

I’ve spent way too much time pondering how to begin this article. So instead of formulating a timely and witty introduction, I’ll be direct: The Blue Jays offense is amazing! You already know that, but it bears repeating. Together, Jays hitters have amassed the league’s second-highest wRC+ while maintaining the league’s second-lowest strikeout rate. This is scary, and this is legit.

Right now, the only team with a higher wRC+ is the Astros. The only team with a lower strikeout rate is… also the Astros. And it’s easy to explain. They don’t have the most power or the best discipline, but they do lead the league in O-Contact%. Even when would-be balls are swung at, they’re either put in play or fouled off. Couple that with a minuscule swinging-strike rate of 8.7%, and it’s a team poised to give opposing pitchers fits. Tenacity wins.

As for the Blue Jays, however, their formula isn’t immediately noticeable. Duh, they have the best hitter on the planet. I know, imaginary voice, but I’m talking about the team as a whole. A few days ago, the Jays routed the visiting Red Sox, outscoring them by eight runs. Let’s consider how the ambush unfolded. Nathan Eovaldi had managed to salvage a rough start until the fifth inning, when Teoscar Hernández unleashed his full strength against a first-pitch fastball:
