For the purposes of researching this article, I went through Baseball Savant and watched several of Luis Arraez’s hits from the 2023 season. You can tell what kind of a heater he’s on by how the broadcast booth reacts when he gets a hit. Marlins play-by-play man Paul Severino, declaring that Arraez was in the midst of yet another multi-hit game, would chuckle as the ball touched outfield grass. On one occasion, Phillies announcer John Kruk muttered, “Jesus!” as Arraez dropped a triple down the right field line.

Arraez is so hot it’s entered the realm of the absurd. Through 15 games, he’s 24-for-51, mostly on singles that army crawl past bewildered infielders or fall softly in front of outfielders. As of Monday afternoon, he has yet to hit a ball with an exit velocity of 100 mph or greater. Ryan Mountcastle, who’s hitting .217 to Arraez’s .471, has 25 such batted balls.

The obvious thing to do in this situation would be to point out all the ways Arraez is getting lucky. He’s a fringy runner with a ninth-percentile (ninth-percentile!) hard-hit rate and a BABIP of .500, and so on and so forth. And ordinarily, I am the kind of relentless downer who goes around ruining other people’s good time. (Hope you enjoyed those wonderful shrimp tacos you had for lunch; the sea is full of microplastics and you’re going to die someday.) But I’m declaring Arraez’s hot start to be a negativity-free zone.

So let’s get to it. Is Arraez some kind of a wizard, or is he just getting lucky? The answer is yes. Read the rest of this entry »

The Oakland Athletics entered the season with low expectations. After completing their two-year fire sale by trading Sean Murphy to Atlanta for a package that was generally agreed to be quite light and adding minimal talent in free agency, the Opening Day ZiPS projections forecasted them to win just 69 games; their playoff odds were just 2.9%. Still, that total would have tied them with Pittsburgh, Cincinnati, and Kansas City, while Colorado and Washington saved them from the honor of being projected for the league’s worst record. Two weeks later, the A’s sit at a miserable 3-13, below any of the other bottom feeders. While the team’s collective 94 wRC+ isn’t good by any means, it’s not the reason their run differential is 29 runs worse than anyone else’s. Instead, their pitching staff has been one of the worst in recent memory.

With 125 runs surrendered in 16 games, Oakland has pitched far worse than any other team in the league. The 29th-place White Sox are closer in runs allowed to the 12th-place Astros than they are to the last place A’s. The A’s 188 ERA- and 156 FIP- paint a similar picture. In fact, with a 7.60 ERA thus far, this Oakland squad has the third-worst staff ERA through 16 games of any team in the integration era, only outdone by the 1951 St. Louis Browns and the 1955 Kansas City A’s; those teams each went on to allow at least 5.7 runs per game across the entire season. A simple glance at each team’s 2023 strikeout and walk rates shows a clear gulf between Oakland and the field:

Many of these struggles have occurred in a handful of huge blowups, as the A’s have surrendered double digit runs in six games. On the second day of the season, fans excitedly watched the major league debut of Shintaro Fujinami, who showed flashes of both elite stuff and extreme wildness in NPB. After sitting down his first six batters and notching four strikeouts, Fujinami allowed eight baserunners, three via walk, while recording just one out before being lifted from the game. His second start also featured a blowup inning after cruising the first time through the order; he exited after 4.1 innings, with four walks and a hit batsman. On Saturday, in the A’s 15th game of the season, Fujinami recorded the team’s first quality start with six innings of one-run ball, but he still took the loss after coming out for a seventh inning and adding two more runs to his line.

The Brewers announced on Sunday that pitcher Brandon Woodruff’s shoulder pain has been diagnosed as a mild subscapular strain, meaning a trip to the injured list was in order. But while the word “mild” appears, the result is anything but, as it’s almost certain that he will spend significantly more time on the IL than the minimum 15 days, and a trip to the 60-day IL may be in order.

The good news is that the team doesn’t believe, at this time, that surgery will be required. But in talking about the injury, Woodruff didn’t sound like a player who was particularly optimistic about a quick return.

“If this was something that happened midseason, All-Star break, right before or after that time, I would probably end up being done, to be honest, for the season.”

[…]

“I’m not going to rush this, I’m not going to come back too early just for the sake of coming back early,” Woodruff said. “That’s just not going to do anybody any good. I’m going to take my time, I’m going to listen to my body and trust the rehab process and just go through that, and hopefully come back at whatever point that is throughout the season and then try to finish up strong.”

The subscapularis is one of four muscles that make up the rotator cuff and is a stability muscle that is key to keeping the shoulder from being dislocated. It’s one of the muscles less likely to be injured, but the recovery time for pitchers has been significant. Corey Kluber missed three months in 2021, and Justin Dunn has been shut down since the start of spring training, though his case is complicated by the fact that his shoulder problems are more longstanding. In a small study of eight professional players in Japan with similar injuries, the five pitchers had a mean time of 81.5 days until return to play, with a significance variance among the players that wasn’t based on severity of the injury. Looking back at the players 21 months after their injury, none of the eight suffered a recurrent injury to the muscle. Read the rest of this entry »

The best article I’ve ever read about Adam Ottavino was written on this site. Travis Sawchik wrote it, years ago, and ever since then I’ve found myself following Ottavino’s career and thinking about that article. The season after he revamped his pitching arsenal by throwing by himself in a Manhattan storefront, he had a career year for the Rockies. The season after that, he returned to New York to pitch for the Yankees, and after a brief detour to Boston in 2021, he’s back in his hometown pitching for the Mets. Now, though, he’s doing it with some new tools.

That fateful offseason, Ottavino learned to command his slider. But that wasn’t the pitch he was trying to learn at the start. Take a look at his pitch mix by year, and you can see the cutter he planned on integrating:

Big sweeping sliders like the one Ottavino throws pair well with sinkers, and he changed his primary fastball accordingly. But sweeping sliders and sinkers both display large platoon splits, so he also picked up a cutter to pair with his two primary pitches. That was the idea, at least. In practice, he didn’t throw his cutter much against lefties, and by 2020 he didn’t throw it much at all. From 2020 through ’22, he threw that cutter only 3.7% of the time overall.

In a perhaps related development, Ottavino has gotten shelled by lefties since 2018: from that year through ’22, he allowed a sterling .256 wOBA against righties and a middle-of-the-road .313 mark against lefties. That’s hardly surprising; he basically only threw two pitches, and neither of them are at their best against opposite-handed batters. The Yankees used him more or less as a righty specialist and then traded him to the Red Sox in a salary dump to make their bullpen work more efficiently. Read the rest of this entry »

The Rangers have spent virtually all of the young season atop the AL West, and they solidified their position this weekend by taking two out of three games from the Astros in Houston. Though they’re off to their best start in seven years, they lost Corey Seager to a left hamstring strain last week and may not get him back for a month, threatening the momentum they’ve built.

The 28-year-old Seager came up limping while running out a fifth-inning double against the Royals last Tuesday; he grabbed at his left hamstring shortly after rounding first base, hopped his way to second in awkward fashion, and then started back to the Rangers’ dugout before the trainer could reach him. On Wednesday, general manager Chris Young told the media that an MRI revealed Seager suffered a Grade 2 strain.

This is unfortunately an all-too-familiar position for Seager — on the injured list — and an all-too-familiar injury for him as well. While a member of the Dodgers in 2019, he missed a month with a similar left hamstring strain, not to be confused with the myriad other injuries the shortstop suffered with the Dodgers, including a torn ulnar collateral ligament requiring Tommy John surgery in 2018 and a right hand fracture in ’21. After playing 157 games and winning NL Rookie of the Year honors in 2016 and then 145 games the next year, Seager played in a total of 307 games out of a possible 546 from ’18 to ’21, the equivalent of 91 games over a full season.

After signing a 10-year, $325 million deal in December 2021, Seager was healthy enough to play in 151 games last year, his highest total since 2016, but despite clubbing a career-high 33 homers, he slumped to a .245/.317/.455 line, setting full-season lows in all three slash stats. That was still good for a respectable 117 wRC+, five points higher than his injury-marred 2019, but it wasn’t exactly what the Rangers had in mind when they signed him. Read the rest of this entry »

This young season has already introduced us to a few unique offerings. Brent Honeywell Jr. throws a true screwball. Kodai Senga throws a ghost fork. But one fascinating pitch has flown somewhat under the radar: Ian Hamilton’s slambio.

Maybe it’s because of the right-hander’s lack of a pedigree, or his status as a non-roster invitee during spring training. After all, Hamilton is a 27-year-old reliever who struggled through injuries and ineffectiveness over the past four years. At the same time, he looked like a find as recently as 2018, when he pitched to a 1.74 ERA and 2.44 FIP across 51.2 innings between Double- and Triple-A; he even averaged 96.7 mph on his heater in a brief eight-inning callup. The next season, he seemed poised to play an integral part in the White Sox bullpen, but he was struck by a foul ball while rehabbing separate shoulder and head issues stemming from a car accident. His poor luck nearly brought his career to an end, but he finally began to feel back to normal this offseason.

If you didn’t know about Hamilton before, I’ll be the first to tell you that he has been a joy to watch this season, not only because of his unique offering but also his comeback story, parlaying his rediscovered health into a spot in the Yankees’ pen, where he’s found early-season success with a resurgent fastball (averaging 95.4) and the slambio. The latter pitch has been nothing short of excellent thus far: a ludicrous 29.9% swinging-strike rate and worth 3.8 runs, which rank third and tied for fourth, respectively, among the 85 sliders thrown at least 50 times this year (as of Saturday night). The pitch’s unusually high rate of called strikes, 15.6%, given its whiffiness, also places it second among the 85 sliders in CSW%. Read the rest of this entry »

On Friday, the Giants announced a five-year, $90 million contract extension with star right-hander Logan Webb. The 26-year-old Webb came to national attention during the 2021 NLCS, in which he allowed a single run across two starts against the Dodgers, striking out 17 and walking one over 14 2/3 innings. Across 2021 and 2022, Webb was 12th in baseball in pitcher WAR, one spot behind Gerrit Cole, and 20th in ERA among pitchers with at least 200 innings pitched, one spot ahead of Shane Bieber.

Webb was due to reach free agency after the 2025 season. This contract will buy out his two remaining arbitration years for a total of $20 million, then pay him $23 million, $23 million, and $24 million from 2026 to 2028. It’s a deal indicative of Webb’s special status in the Giants’ organization, and it could nonetheless be an enormous bargain for the team. Read the rest of this entry »

Billy Wagner was the club’s closer when Craig Kimbrel joined the Atlanta Braves in 2010. Thirty-nine years old by season’s end, Wagner logged the last 37 of his 422 career saves, and he was as dominant as ever while doing so. Over 69-and-a-third innings, the left-hander fanned 104 batters while allowing just 38 hits.

Kimbrel, who was just 21 years old when he debuted that May, was every bit as overpowering. In 21 appearances comprising 20-and-two-thirds innings, the rookie right-hander fanned 40 batters while allowing just nine hits. Along the way, he recorded the first of what is now 395 saves.

I’ve had a Hall of Fame vote for three years, and in each of them I’ve put a checkmark next to Wagner’s name. This coming winter, I plan to do so again in what will be his penultimate year on the ballot (assuming he doesn’t get voted in; Wagner received 68% of support in his last go-round).

Kimbrel will soon celebrate his 35th birthday, and while the end of his career is fast approaching, he’s still pitching. Will he likewise be getting my vote once his name appears on the ballot? And what about Kenley Jansen? Still going strong at age 35, he’s also got 395 saves, tying him with Kimbrel for seventh on the all-time list, directly behind Wagner.

Let’s compare some of their numbers:

Wagner: 422 saves, WPA 28.40, 187 ERA+, 2.73 FIP, 6.0 H/9, 11.9 K/9.
Kimbrel: 395 saves, WPA 22.99, 174 ERA+, 2.38 FIP, 5.2 H/9, 14.3 K/9.
Jansen: 395 saves, WPA 24.72, 161 ERA+, 2.44 FIP, 5.8 H/9. 13.0 K/9. Read the rest of this entry »

Orlando Arcia getting the nod for the starting shortstop job in Atlanta raised some eyebrows this spring. After all, he had looked more like a utility infielder in recent years than a viable starting shortstop, and it felt a bit like that ship had long since sailed. The present and future was Vaughn Grissom, our top Braves prospect last year after the graduations of Spencer Strider and Michael Harris II. Grissom didn’t exactly struggle in his debut last fall, whomping pitchers to the tune of a .293/.353/.440 line, a triple-slash that would be viable for a first baseman, let alone a guy who can handle short. Yet it was Arcia who ended up with the job in the spring. It didn’t even seem like the typical service time shenanigans, such as the Cubs swearing that Kris Bryant needed a couple weeks to learn to be a better player than Mike Olt; Grissom already had nearly a third of a year of service time, which would have made it a bit arduous to maintain that façade.

Arcia didn’t disappoint in early play: In 13 games, he hit .330/.400/.511 and looked fairly comfortable playing short regularly for the first time in a few years. Unfortunately, a Hunter Greene fastball had other plans for the position; his upper-90s heat hit Arcia’s wrist during an at-bat, knocking him out of Wednesday’s game against Cincinnati, replaced by Ehire Adrianza. Initial x-rays didn’t reveal a fracture, but an MRI and CT scan on Thursday showed a microfracture, sending him to the injured list. This appears to be a minor injury, and it appears as if Arcia will only miss a couple weeks of play. Cookies don’t crumble in identical ways, but Nick Castellanos suffered this injury in 2021 and only missed a couple of weeks.

If there were service time issues involved, the Braves could have very easily plugged in Adrianza or Braden Shewmake for a couple of weeks and continued to let Grissom work on his defense in the minors (he was so-so at best in the majors last year with the glove). But finding time at short for Grissom, who by all reports took his demotion with humility, was still the upside play. Just as Arcia didn’t disappoint early on, he performed very well for Triple-A Gwinnett, with a 1.044 OPS in 10 games. Read the rest of this entry »

When the Braves won the World Series in 2021, Ronald Acuña Jr. was a bystander, as a torn anterior cruciate ligament in his right knee knocked him out for the second half of the season and the entire postseason. He returned to action near the end of April last year, but while he was the Braves’ second-most valuable outfielder — which wasn’t saying much due to the slumps and calamities that befell the team’s other fly chasers — his performance was far short of the high standard he’d set since debuting in 2018. With a strong start to his 2023 season, Acuña is showing signs of recovering his pre-injury form, though his performance in a couple of areas does raise concerns.

After hitting a sizzling .283/.394/.596 (157 wRC+) in 82 games before tearing his ACL in 2021, Acuna dipped to .266/.351/.413 (114 wRC+) in 119 games last year. It wasn’t a bad performance; his wRC+ ranked among the top 30 of all outfielders, and his 2.1 WAR prorates to about 2.6 per 650 PA. On a team where all of the other outfielders besides rookie Michael Harris II — namely Travis Demeritte, Adam Duvall, Robbie Grossman, Guillermo Heredia, and Eddie Rosario — netted -1.1 WAR, Acuña’s contribution wasn’t an unwelcome one, helping the team win 101 games. Yet his season was well shy of the elite level that he set for himself pre-injury, with a 140 career wRC+ and 6.0 WAR per 650 PA. After all, this is a player whom Dan Szymborski had once projected as the most likely to supplant Mike Trout as the game’s best in terms of WAR.

Acuña missed his chance for that, but he’s still just 25 years old, and through the first two weeks of the season, he’s hitting .370/.452/.537 through 62 plate appearances. Already he has three three-hit games and four two-hit games under his belt, and he’s helped the Braves jump out to a 9-4 record even while dealing with numerous injuries to their rotation and lineup.
