The Lurking Influence of Batted Ball Spin

Dodger Stadium
Gary A. Vasquez-USA TODAY Sports

If I may, I think the uncertainty regarding this season’s offensive environment has made us a bit paranoid. Are hitters lagging behind pitchers due to an irregular spring training? Is the ball not traveling like it once did because it’s been replaced yet again, or is the mass introduction of humidors to blame? Or worse, has MLB introduced multiple balls into the game, some of which are being used in certain games to boost action or influence outcomes?

That last theory has been floating around my Twitter feed for a while now. I’m not going to discuss whether it’s true, but I brought it up because supporters of the multiple ball theory will often compare two batted balls with near-identical exit velocities and launch angles. One ends up traveling more than the other, despite all the indications that it should not. Aha! Something must be up.

In response, a lot of people have suggested batted ball spin as an explanation. Maybe one ball came off the bat with backspin and the other came off with topspin, which would drag the ball down as it traveled through the air. Unfortunately, since data on batted ball spin isn’t available on Baseball Savant, this might seem like a dead end. Don’t worry, though: I had some leftover Trackman data on 2021 NCAA Division I baseball games from a piece that Eric Longenhagen and I collaborated on during last year’s Draft Week, and they contain mostly complete readings on the spin of a batted ball. Could we use collegiate baseball to learn about the odds and ends of batted ball spin, and what it tells us about hitting? Read the rest of this entry »


Player Evaluation on the Moon

© James Lang-USA TODAY Sports

A quick word of warning: this one is pretty abstract. If you like baseball math, it’s definitely got that. If you like analysis of the 2022 major league season, it absolutely does not have that. I think it’s pretty fun, but if that’s not your cup of tea, this one might not be for you. Anyway: on to the nonsense!

I’m the kind of maniac who likes to play baseball video games when I’m not writing about baseball. Right now, that’s Out Of The Park 23, specifically the Perfect Team mode. It’s a baseball simulation where you collect cards representing current and historical players, build teams, and then play simulated games against other players’ teams.

The headline mode of the game lets you collect whoever you want and battle against your opponents’ best shot – peak Mickey Mantle against peak Tex Hughson, say. That’s fun in its own way (for what it’s worth, Mantle strikes out more than you’d like when facing top-tier competition), but I’m more interested in another mode the game offers: tournaments where you match a limited pool of your players against a limited pool of opponents.

Injury Rundown: Kershaw, Megill, Luzardo Get Put on the Shelf

Clayton Kershaw
Charles LeClaire-USA TODAY Sports

Pitchers getting injured is never good news, even in a year in which pitching talent seems relatively easy to come by. Sadly, we got a bunch of high-profile names hitting the IL over the weekend, so here’s a quick Monday rundown in case you were doing something more fun on Sunday than stressing about injuries, like watching the baseball games (non-Giants fans, at least).

Tylor Megill, New York Mets

Given the monumental task of replacing Jacob deGrom in the Mets’ rotation at the start of the season, Megill took his job surprisingly literally, doing his best imitation of the team’s ace. Through six starts, his ERA stood at 2.43 with a nearly identical FIP at 2.44, improving significantly on his major league debut in 2021. Then came the worst start of his professional career — including the minors — as he surrendered eight runs and didn’t even make it through the second inning against the Nationals last Wednesday. Megill can’t point to bad luck either; it’s hard to complain too strenuously about BABIP when you have an xBA of .563 and an xSLG of 1.263.

On the plus side, Megill’s velocity wasn’t down during that disaster of a start, and he didn’t report any discomfort until after the game. One thing that struck me, however, is how much his horizontal release point has changed in a lateral direction throughout the season. From his first start to his last outing, Megill’s horizontal release point has shifted about five inches; those release points tend to be far more consistent in-season, as players are more likely to tinker with this in the winter and spring. Release point inconsistency is a concern, and at least one study that I’m familiar with has linked shifting lateral release points with an eventual need for Tommy John surgery, albeit with low odds (a roughly 5% higher chance of a UCL tear with every 10 centimeters of movement). That’s getting ahead of ourselves, but it’s something to file in the back of your mind.

The decision to put Megill on the IL was made after he experienced soreness during his bullpen on Saturday, with biceps tendinitis as the announced culprit. Colin Holderman got the immediate call-up to take Megill’s spot on the roster, though that may be short-lived, as David Peterson started on Friday. Trevor Williams will get Megill’s start on Monday night against the Cardinals.

In other Mets injury news — of course there’s more, it’s the Mets — catcher James McCann will be out six weeks due to a broken hamate bone. Patrick Mazeika was called up and likely endeared himself to Mets fans more than McCann has by hitting the go-ahead home run in the seventh on Saturday against the Mariners. McCann’s offense has disappeared so quickly over the last year-plus that there’s not likely to be any real consequence for the Mets other than a thinning of the depth chart.

Jesús Luzardo, Miami Marlins

Amid a promising comeback campaign, Luzardo took a step back last week, walking four and allowing four runs in 2.2 innings against the Diamondbacks, bloating his ERA to 4.03. Like Megill, there were no suspicious velocity dropoffs — something to watch for given Luzardo’s injury history — but he reported forearm soreness after the game. In “crossing our fingers” news, he did not believe the pain was similar to what he experienced before his first Tommy John surgery, back when he was a high schooler in 2016:

I just started feeling a little something in the San Diego game, towards the back end of it, but nothing when I was pitching or anything like that. It was more just a little soreness. I kind of backed off a little between my starts. There wasn’t really pain or anything, more like stiffness.

The Marlins held off until this weekend to place Luzardo on the IL, retroactive to his May 10 start, when it became evident that he would be unavailable. It seems that Cody Poteet, already stretched out a bit in relief of Luzardo against Arizona and not used since, will get the spot start on Tuesday, with Sandy Alcantara going on Monday.

As for replacing Luzardo long-term, it doesn’t appear as if the Marlins plan to recall top prospect Max Meyer to fill the spot. My reading of the tea leaves is that they’re not going to push Edward Cabrera up soon as a replacement either; while he’ll get another chance in the not-too-distant future, I think Saturday’s start against Triple-A Nashville would have been a few tune-up innings rather than a 90-pitch outing if a callup was imminent.

Short of any additional bad news, it’s entirely possible that, with two off days in the next week, Luzardo may only miss just the one start.

Clayton Kershaw, Los Angeles Dodgers

Kershaw was a late scratch on Friday against the Phillies, pushing Walker Buehler’s start up a day on normal rest. Kershaw has a history of lower back pain and at least one instance (2012) of hip impingement, so the Dodgers are being careful with him. The culprit this time is inflammation of the SI joint, which, I believe, is the sacroiliac joint and not the Sports Illustrated joint; on the pelvis, it’s between the hip and the spine. As I did not attend Hollywood Upstairs Medical College, and my medical knowledge is primarily evaluating how sick I’ll feel if I eat some deliciously spicy food, let’s consult actual doctors here:

Biomechanically, the sacroiliac joint performs several functions. Primarily, its purpose is to attenuate the distribution of force loads from the lower extremities. It functions both as a shock absorber for the spine above and converts torque from the lower extremities into the rest of the body.

As pitching largely involves transfers of force between body parts, it’s understandable why the Dodgers see the need to be cautious. Last year was the first time Kershaw was placed on the IL with elbow issues, and given that it scared them enough to shut him down quickly for the postseason, this is not unexpected caution.

To replace Kershaw on the roster, the Dodgers called up Michael Grove, who got the start on Sunday and may get another down the road, though with a very quick hook. Andre Jackson looked like a rotation fallback option at the start of the season, but he’s failed to finish the third in each of his last three starts for Triple-A Oklahoma City, allowing 10 walks in just 3.1 innings.


FanGraphs Power Rankings: May 9–15

It was an eventful week in baseball, as we saw some history made and a lot of fun on the field. There were some big moves in the power rankings too.

A reminder for how these rankings are calculated: first, we take the three most important components of a team — their offense (wRC+), and their starting rotation and bullpen (a 50/50 blend of FIP- and RA9-, weighted by IP share) — and combine them to create an overall team quality metric. New for this year, I’ve opted to include defense as a component, though it’s weighted less heavily than offense and pitching. Some element of team defense is captured by RA9-, but now that FanGraphs has Statcast’s OAA/RAA available on our leaderboards, I’ve chosen to include that as the defensive component for each team. I also add in a factor for “luck,” adjusting a team’s win percentage based on expected win-loss record. The result is a power ranking, which is then presented in tiers below.

Tier 1 – The Best in the AL
Team Record “Luck” wRC+ SP- RP- RAA Team Quality Playoff Odds
Yankees 25-9 0 122 78 72 -1 178 98.6%
Astros 23-12 0 116 88 82 10 179 97.1%
Angels 24-13 -1 120 82 102 3 167 82.1%

The Yankees remain at the top of the rankings after winning six of their seven games last week, including a two-game sweep of the Blue Jays and a series win against the White Sox. Even as scoring remains depressed throughout the game, the Yankees have continued to mash despite the deadened ball. They hung 32 runs on Chicago during their weekend series and will host the Orioles for four games to start this week — I imagine plenty more runs should be scored. Oh, and Nestor Cortes has suddenly ascended to a place among the game’s elite pitchers — he took a no-hitter into the eighth inning on Monday.

The Astros stretched their win streak out to 11 games before falling to the Nationals 13-6 on Saturday. They got right back on track Sunday, shutting out Washington 8-0. That’s the fourth shutout they’ve posted in their last seven games, and the sixth stretching back to the beginning of their current red hot streak. Justin Verlander is pitching like he never had Tommy John surgery, Jake Odorizzi hasn’t allowed a run in three straight starts, and Luis Garcia has been exceptional over his last two.

Hunter Greene and the No-Hitter That Wasn’t

Hunter Greene
Charles LeClaire-USA TODAY Sports

It was weird, it was wild, it was perhaps a bit irresponsible, and it was certainly bittersweet. On Sunday in Pittsburgh, Reds rookie Hunter Greene was dominant, setting a career high for strikeouts and combining with reliever Art Warren to hold the Pirates hitless for the entire afternoon. Yet when it was all said and done, Cincinnati — which had won six out of its last nine after starting the season 3–22 — found a new way to lose, 1–0. Greene and Warren didn’t even get credit for an official no-hitter, combined or otherwise.

The game’s only run scored in the bottom of the eighth inning. After Greene issued a pair of one-out walks to Rodolfo Castro and Michael Perez to push his pitch count to 118 — oh, we’ll get to that — manager David Bell pulled him in favor of Warren, who walked Ben Gamel, then induced a chopper by Ke’Bryan Hayes. Second baseman Alejo Lopez briefly bobbled the ball, and while he still threw to shortstop Matt Reynolds in time to force Gamel, Reynolds’ throw to first base was too late to complete the double play.

The Reds themselves managed just four hits against starter José Quintana and relievers Chris Stratton and David Bednar, the last of whom set down the side 1-2-3 in the ninth. Thus they joined a short and dubious list, becoming just the fifth team to hold their opponents hitless for eight innings but lose because they were nonetheless outscored. Such efforts used to be considered no-hitters, but in 1991, MLB’s Committee for Statistical Accuracy tightened the official definition of the feat, ruling that those falling short of nine innings would not receive such a designation. That put the Reds in this company:

Eight No-Hit Innings But Lost
Pitcher(s) Team Opponent Date Score
Silver King Chicago (PL) Brooklyn (PL) 6/21/1890 0-1
Andy Hawkins Yankees White Sox 7/1/1990 0-4
Matt Young Red Sox Cleveland 4/12/1992 1-2
Jered Weaver (6), Jose Arredondo (2) Angels Dodgers 6/28/2008 0-1
Hunter Greene (7.1), Art Warren (0.2) Reds Pirates 5/15/2022 0-1
SOURCE: nonohitters.com
PL = Players League

The most infamous of such games is that of Hawkins, who allowed four eighth-inning runs via a combination of three errors and two walks, all with two outs; he did walk five overall, so his outing was kind of a mess to begin with. Greene and Warren combined to walk six, but they were the only one of the five teams above to lose after eight hitless innings without being charged with an error as well. Congrats on discovering that new way to lose, I guess. Read the rest of this entry »


Dallas Keuchel’s Changeup Has Stayed the Same, While Brent Suter’s Has Evolved

© Matt Marton-USA TODAY Sports

The Learning and Developing a Pitch series is back for another season, and once again, we’re hearing from pitchers on a notable weapon in their arsenal. Today’s installment features a pair of southpaws — White Sox starter Dallas Keuchel and Brewers reliever Brent Suter — on their changeups.

———

Dallas Keuchel, Chicago White Sox

“A changeup was the first pitch I learned growing up. My dad never let me throw a breaking ball. He just had me split my fingers and try to throw a fastball as hard as I could. That was probably … let me think for a moment with my Rolodex here. I was maybe eight years old? Regardless, I don’t know how many miles per hour it was off, but it had some good deception and movement, so that’s what I rolled with through a lot of my childhood.

“I didn’t grip it like a palm ball, but a kid’s fingers are obviously smaller than the baseball, so we just tinkered with splitting the two fingers. What stuck was splitting three fingers together, instead of a circle change. It’s more of a three-finger prong changeup. When I say prong, what I mean is like a fork. But it worked well for me. It just kind of rolled off, and I’d get some whiffs and some weak contact. Read the rest of this entry »


Sunday Notes: Taylor Davis Wants To Manage (or Work in a Front Office)

Taylor Davis plans to stay in the game once his playing days are over. Currently on the roster of the Indianapolis Indians — Pittsburgh’s Triple-A affiliate — the 32-year-old catcher intends to become a coach, a manager, or a decision-maker in a front office. He’s already received overtures for one of those positions.

“The question does get asked,” said Davis, whose resume includes 22 MLB games over parts of four seasons. “It’s something that started even before I got to the big leagues. The first time I got asked if I wanted to coach was in 2017. That was early in the year, and then I ended up making my debut later that season. Obviously, I want to play for as long as I can, but after it’s done, doing something within the game is what I want.”

Managing might be his primary down-the-road goal, but the erstwhile Chicago Cub would also be well-suited for a corner-office role. Asked about that possibility, Davis said that he’d be equally happy wearing a polo shirt or a uniform. Roster construction and “the whole business side of the game” are among his interests. So is the data that influences, and often dictates, the decisions that are made.

“I dive into analytics probably more than the average player,” the veteran catcher explained during spring training. “I try to understand where teams are coming from, where agents are coming from, and where a player is going to come from in terms of analytics. It’s a piece of the puzzle that’s become increasing important.” Read the rest of this entry »
