Pouncing Tigers Snared by Injuries to E-Rod and Greene

Eduardo Rodriguez
Rick Osentoski-USA TODAY Sports

May was a successful month for the Tigers, a franchise which in recent years has been lacking in happily remembered calendar pages. Detroit’s .577 winning percentage in May (15–11) is its best full month since a .615 mark (16–10) all the way back in July 2016. And while it would be a stretch to say that everything has been coming up bengal, given that the team’s run differential is still slightly in the negative for the month, the bleakness of the AL Central has allowed the Tigers to come within a game of the division lead. Even Spencer Torkelson, whose bat disappeared in 2022, has been playing better baseball, putting up a 119 wRC+ in May. Unfortunately, fate wasn’t even kind enough to give Detroit the whole month; a couple of days before the calendar flip, injuries to Eduardo Rodriguez and Riley Greene have ended May on a decidedly sour note.

These Tigers certainly aren’t strangers to injury. Every team faces injuries sooner or later, but Detroit managed to win in May despite an entire rotation’s worth of promising pitchers — Tarik Skubal, Matt Manning, Spencer Turnbull, Casey Mize, and Beau Brieske — out with injuries. The contributions of Rodriguez and Greene had a lot to do with that. The former’s hot April start continued in May with a 2.03 ERA/2.61 FIP over five outings; the latter hit a star-level .365/.435/.573 for the month. That came crashing down on Tuesday with two bits of very unwelcome news. Read the rest of this entry »

What’s the Matter With Alejandro Kirk?

Alejandro Kirk
Nick Turchiaro-USA TODAY Sports

The 2022 Blue Jays won 92 games and finished second in the American League in runs scored, and Alejandro Kirk had a lot to do with that. Hitting .285/.372/.415 and playing better defense behind the plate than most expected when he was a prospect, he formed a dynamite catching chimera with Danny Jansen and Gabriel Moreno, who was sent to Arizona this offseason. The resultant pairing of Kirk and Jansen projected to give the Blue Jays the best catching situation in baseball in 2023. But while the rest of the top catchers in the majors have worked out about as expected, Toronto’s have not, combining to hit a respectable but disappointing .232/.311/.384. As the younger and much less experienced of the two, with more time to grow as an offensive player, Kirk’s struggles concern me more.

It’s easy to forget how quickly Kirk rocketed through the minors in recent years. After playing mostly in High-A Dunedin in 2019, the Blue Jays were interested enough in his talent to put him on the taxi squad at the start of September 2020, even getting him into nine games, seven as a catcher. The following season, he only played a couple of weeks at Triple-A Buffalo before becoming a permanent major leaguer. While a promotion that aggressive does happen once in a while, there’s no situation that I can remember in which a team promoted a catcher who wasn’t an extremely polished defender that quickly. He hit .242/.328/.436 — a solid triple-slash for any catcher, but exciting for a player with such little high-level experience. Perhaps as importantly, while Kirk didn’t fool anyone into thinking he was the next Yadier Molina with the glove, he played far better defensively than the DH-pretending-to-be-a-catcher archetype that players like Zack Collins fall into. But Kirk’s .234/.353/.324 line so far is not what people expected in the follow-up season, and while the resulting wRC+ of 96 is far better than trainwreck status, it’s also far from the stardom he displayed last year.

When you see a dropoff like that, especially in a fairly short stretch of games, you frequently see a BABIP blip along with it. But while Kirk has dropped about 40 points of BABIP since last year, his hit profile supports a fairly low BABIP. In fact, ZiPS thinks that he’s “earned” a .249 BABIP based on how he’s hit this year, lower than his actual BABIP of .261. The plate discipline stats also show no red flags; he still makes good contact and isn’t suddenly offering more often at worse pitches.

The icky part of Kirk’s seasonal line involves the loss of power, and unfortunately, the drop in both his exit velocity and loft is real; four miles per hour and seven degrees of launch angle are not small deviations. For the Statcast era, I took every player who put 75 pitches into play in consecutive years, ranked their dips in exit velocity and launch angle (out of 2,389 players), and found those with the biggest dropoffs, using the average of their ranks (we’re trying to get a general idea, so a very simple method is fine). Here are the results:

Carlos González 2018-2019 -2.3 -7.3 233 30
Christian Yelich 2020-2021 -3.4 -4.5 88 183

Kirk ranks highly in terms of dropoff in these stats, so it’s not surprising to see his power evaporate. It’s also not something that bodes well. ZiPS and other projection systems deal with these issues in a more scientifically sound fashion than this, but there are a lot of fading players on this list. The ones that did improve overall in seasons after the two-year window, such as Díaz and Acuña Jr., managed to reverse this process. I went down the top 50 players on this list and found that this held true as well. And Kirk actually showed some dropoff from 2021 to ’22 despite his excellent performance, suggesting that the seeds of a future issue had already been sown.

One culprit here is that he is simply topping hard pitches down in the zone, whereas last year he was getting just enough loft to squeeze a bunch of hits out of them; he hit .452 on low fastballs and lifted the majority of them with a positive launch angle. This season, only three of 13 low fastballs haven’t been driven into the ground, and Kirk has lost about eight degrees of launch angle on average compared to last year. It’s not just luck either: he’s hitting them with less velocity, resulting in an xBA of .231 compared to .336 last year.

The exit velocity issue is important for Kirk because he’s not a fast player and hits a lot of grounders; he’s not going to be legging out many soft infield hits, so he needs to hit the ball hard. Groundball BABIP is very sensitive to exit velocity, as unlike fly balls, there’s no sweet spot where a soft hit becomes an impossible-to-field bloop.

BABIP by Hit Type and Velocity, 2021-2023
Exit Velocity GB BABIP LD BABIP FB BABIP
95+ mph .364 .659 .157
90-94 mph .235 .550 .036
85-89 mph .197 .542 .020
80-84 mph .160 .590 .029
75-79 mph .139 .677 .104
<75 mph .162 .588 .609

And if you check the Statcast leaderboard in terms of year-to-year change, Kirk is near the top of the list in terms of most increased topped contact rate.

The good news is that the full model of ZiPS is aware of these hit tendencies and still thinks Kirk is going to be alright over the long haul, though his problems right now have increased the downside risk, pushing his projections down from the 3.5–4.0 WAR range they were in before the season:

ZiPS Projection – Alejandro Kirk
Year BA OBP SLG AB R H 2B 3B HR RBI BB SO SB OPS+ DR WAR
2024 .261 .350 .405 410 48 107 20 0 13 56 55 57 0 110 2 2.9
2025 .260 .349 .407 420 49 109 20 0 14 58 57 57 0 111 3 3.0
2026 .257 .347 .405 420 49 108 20 0 14 57 57 56 0 109 3 3.0
2027 .258 .347 .407 415 48 107 20 0 14 56 56 54 0 110 3 3.0
2028 .254 .345 .398 405 46 103 19 0 13 54 55 53 0 107 2 2.7
2029 .251 .341 .389 391 44 98 18 0 12 51 53 51 0 104 2 2.4
2030 .249 .339 .382 374 41 93 17 0 11 48 50 49 0 101 1 2.1

These types of changes aren’t good, but they’re also not death sentences for careers and can be reversed. Kirk, even while struggling, still retains a lot of the characteristics that made him such a good hitter last year. The key to improving his baseball game right now may be working on his golf game and re-embracing the modern trend of turning low pitches into long drives rather than worm-burners.


Can the Oakland A’s Catch the ’62 Mets?

Oakland Athletics
Stan Szeto-USA TODAY Sports

From entertainment to finance to sports, every category of human endeavor has its own benchmark for incompetence. There are a lot of candidates to this title in MLB, but one of the most common invocations for ineptitude is the 1962 Mets. Sure, you can find better examples of hilarious failure in the 19th century, such as the Wilmington Quicksteps, who folded while warming up for a game in 1884 when attendance was zero, with the players having to find their own way home from Delaware. You can find teams that won fewer games, like the Cleveland Spiders. But 19th-century baseball was essentially one step above a traveling medicine show, and by the time the 1962 Mets came into existence, MLB was a thoroughly professional league which would be recognizable by today’s fans.

An expansion team that year, the Mets started off losing their first nine games. Things only got slightly better from there: they finished with 120 losses, the most in modern MLB history. Over 60 years later, the A’s, after a 10–38 start, seem poised to become the new true north of failure. Through the first 48 games (as of Sunday’s games), this year’s Oakland squad is actually two games behind (or ahead of, depending on your point of view) the ’62 Mets, who won 12 of their first 48 games.

In some ways, the A’s are already a sadder case than the Mets are. The Mets were an expansion team, hampered by very miserly rules for the expansion draft which left them (and the Houston Colt .45s) with long roads to putting talented players on the field. By all accounts, the team was trying to win, and fan interest was high relative to the performance, with a million fans putting New York in the middle of the pack, attendance-wise. The A’s, on the other hand, are desperately trying to move to Las Vegas or whatever other city without baseball is willing to throw a billion dollars their way and are averaging under 9,000 paying fans — not attending fans — per game. The Mets may have had one of the worst first basemen in the league in “Marvelous” Marv Throneberry, but at least media didn’t have to evacuate an area because of possum urine. Combine the possums with a few dozen cats and whatever else is lurking, and the WhateverItsCalledThisYear Coliseum may be best described as an open-air wildlife refuge that sometimes has baseball games.

But what are the odds that the A’s lose 120 games or even more by the end of the 2023 season? To get an idea, I fired up the ZiPS projection system to get the latest tales of woe from the AL West. Read the rest of this entry »

Juan Soto Is Finally a Bright Spot for the Padres

Juan Soto
Nick Wosika-USA TODAY Sports

Players the caliber of Juan Soto are rarely available via trade, so when the Padres acquired him via trade last summer from the drowning Nationals, it made a huge splash on the level of dropping a Sherman tank into your neighborhood swimming hole. But rather than continue his previous level of superstardom, he struggled to meet expectations in San Diego. His .236/.388/.390 line was still enough for a solid wRC+ of 130, but relative to his normal level of excellence, it’s hard to call that line anything but a disappointment.

Soto’s start in 2023, though, pales even next to his post-trade performance last year. April 17 may be the nadir of his career in San Diego: the Padres were shut out for the second game in a row, and he put up his fifth consecutive hitless game, leaving him with a triple-slash of .164/.346/.361. For the calendar year ending on that day, he was hitting .230/.391/.435 and had compiled 3.5 WAR — good enough for mere mortals, but not entities made of sterner stuff.

Around this time, Harold Reynolds talked a bit on MLB Network about Soto’s swing and the changes he was making. While I’ve criticized Reynolds plenty for his general analysis when it crosses into the jurisdiction of analytics, I bookmarked this video at the time, as the analysis rang true to me. He believed that Soto’s tinkering would pay dividends, and whether it’s a coincidence or not, he’s looked a lot more like the Soto we love over the last month. In 23 games since then and through Sunday’s action, he hit .321/.447/.571 and amassed 1.2 WAR, the kind of MVP-level production we’ve expected to see from him in mustard and brown and largely have not.

The Unbreakable Casey Schmitt

Rick Scuteri-USA TODAY Sports

In the sea of prospects, Casey Schmitt barely caused a ripple. The only Top 100 list the infielder made before this season was Baseball Prospectus’ Top 101; he just squeezed in near the end at no. 94. The computer projections were no kinder, with ZiPS only projecting him as the fourth-best prospect in a rather weak San Francisco Giants system, just barely in its Top 200. Yet these limited expectations didn’t stop Schmitt from engulfing opposing pitchers in his first three big league games, as he went 8-for-12 with two home runs and two doubles.

Obviously, having three big games isn’t a guarantee of stardom — or even viability — in the majors. For example, Vaughn Eshelman started his major league career by throwing 13 shutout innings over his first two starts. He only had eight quality starts left in him (out of 28) and was out of the majors two years later. He might be best known for going on what was then the DL as a result of burning himself with a candle. Read the rest of this entry »


Atlanta’s Pitching Injuries Keep Piling Up

Max Fried
Brett Davis-USA TODAY Sports

Bad injury news for a member of your rotation is always unwelcome, so the Braves had a very unhappy Wednesday, with two starting pitchers hitting the IL to go along with a loss in their series closer with the Red Sox.

In Atlanta’s current era of success since its last rebuild, there’s no pitcher that has been more crucial to the team’s fortunes than Max Fried. Since his debut in 2017, he has amassed 14.4 WAR, more than double that of any other pitcher on the roster (next up is Charlie Morton at 6.5). He’s already missed time this season due to an injury, a hamstring strain that cost him two weeks in April. The current injury, however, is far more serious, one that will measure in months rather than days or weeks.

A forearm strain is usually enough to cause serious and forlorn eyebrow-raising, but the silver lining here is that the MRI on Fried’s elbow didn’t reveal an injury severe enough to require surgery. This is especially important given that he already had Tommy John surgery back when he was a prospect with the Padres. That previous procedure cost him part of 2014 and all of ’15, and the basic truth is that though medicine has made progress and that Tommy John surgeries aren’t career-enders to the degree they used to be, repeat procedures have considerably less success. In this 2016 study of so-called revision Tommy John surgery, less than half of the pitchers looked at even pitched in 10 major league games afterward, and they saw their average career length drop in half compared to first-time patients.
