Monday afternoon’s game between the A’s and Yankees ended in impressive fashion for Oakland, with closer Mason Miller buzz-sawing through the top of New York’s lineup to close out a 2-0 victory. The 25-year-old righty struck out Anthony Volpe, Juan Soto, and Aaron Judge consecutively on 14 pitches, mixing eight four-seam fastballs — all with velocities above 100 mph — with four nasty sliders. He absolutely overpowered Judge:

Those fastballs Judge flailed at were clocked at 100.7 mph, 102.2 mph, and 102.5 mph, the last of which wasn’t quite as fast as the 103.3-mph heater Miller used to strike out Soto. Whoosh! Read the rest of this entry »

Thanks to an eight-run fifth inning that included Andy Pages‘ first major league home run, the Dodgers beat the Mets 10-0 on Sunday to avoid being swept at home. Even so, they’re off to a sluggish start this season after committing nearly $1 billion in free agent contracts this past winter and pushing their payroll to a club record $314 million. Maybe they’re not the juggernaut that figure suggests, though even given their star-laden roster, they came into this season as a work in progress.

The Dodgers entered Sunday having lost seven of their past nine games. They dropped the finale of a six-game midwest road trip to the Twins, then two of three to the Padres at Chavez Ravine, followed by two of three to the Nationals and two in a row to the Mets. The skid undid a 10-4 start, and they were in danger of — gasp — sinking to .500 had they lost on Sunday. They weren’t exactly getting steamrolled by powerhouses, either. The aforementioned teams had a weighted projected winning percentage of .472 at the outset of the season, and finished Sunday having produced a .453 winning percentage outside of this nine-game stretch against Los Angeles.

For the Dodgers, run prevention has been the biggest issue. Even with Sunday’s shutout — their first of the season, with eight dominant innings from Tyler Glasnow and one from Nick Ramirez — they’re allowing 4.54 runs per game, 11th in the National League. While they haven’t allowed runs at that clip over a full season since 2005, they allowed exactly the same number of runs over their first 24 games last year while going 13-11, then picking up the pace and winning 100 games. Déjà vu all over again? Read the rest of this entry »

No manager defined the era of baseball marked by artificial turf and distant outfield fences as Whitey Herzog did. As the manager of the Royals (1975–79) and Cardinals (1980, ’81–90) — and for a short but impactful period, the latter club’s general manager as well — he assembled and led teams built around pitching, speed, and defense to six division titles, three pennants, and a world championship using an aggressive and exciting brand of baseball: Whiteyball. Gruff but not irascible, Herzog found ways to get the most out of players whose limitations had often prevented them from establishing themselves elsewhere.

“The three things you need to be a good manager,” he told Sports Illustrated’s Ron Fimrite in 1981, “are players, a sense of humor and, most important, a good bullpen. If I’ve got those three things, I assure you I’ll get along with the press and I guarantee you I’ll make the Hall of Fame.”

Herzog was finally elected to the Hall in 2010, an honor long overdue given that he was 20 years removed from the dugout and had never been on a ballot. He passed away on Monday in St. Louis at the age of 92. Read the rest of this entry »

Coming up through the Dodgers system, Michael Busch gained a reputation as “a bat-only prospect,” a player whose offensive skills far outpaced his defensive ones. So when the Dodgers landed Shohei Ohtani in December, it closed the door on the team finding room for Busch as a DH, and they were already set at first base — Busch’s main position in college — with Freddie Freeman in the fold. Busch needed a trade to clear his path, and in January he got one, a four-player deal with the Cubs. So far, the 26-year-old rookie is off to a flying start, ranking high on the leaderboards after reeling off a streak of five consecutive games with a home run.

Busch’s streak, which ended on Tuesday night in Arizona, took place during the Cubs’ nine-game western road trip, beginning with a game-tying two-run homer off the Padres’ Dylan Cease at Petco Park on April 10. Two days later in Seattle, he went deep off the Mariners’ Ryne Stanek. The Cubs lost both of those games, but he helped them win three straight, starting with a solo shot off Tyson Miller in the seventh inning of a 4-1 win Saturday night, then a two-run homer off Luis Castillo in the fourth inning of a 3-2 win on Sunday. Moving on to Arizona, he didn’t waste any time, connecting off Merrill Kelly in his first plate appearance of Monday’s game, an 11-inning, 3-2 win. Read the rest of this entry »

2:01	Jay Jaffe: Good afternoon, folks, and welcome to my Tuesday chat. Apologies for the technical glitch in terms of the pre-chat queue but we should be up and running.

2:01	Jay Jaffe: Pouring one out for Whitey Herzog, the Hall of Fame manager best known for piloting the Cardinals to the 1982 championship and two other pennants.

2:03

Jay Jaffe: And pouring another one out for Carl Erskine, a true mensch who not only helped the Dodgers to five pennants and their 1955 championship — and threw two no-hitters as well — but became “a fierce champion of human rights, racial equality and, when his late son Jimmy was born with Down syndrome, became immersed in fighting for people with special needs.” The Hall of Fame honored Erskine with the Buck O’Neill Lifetime Achievement Award last summer https://www.indystar.com/story/sports/2024/04/16/indianas-carl-erskine…

2:04	Jay Jaffe: Forgot about Holtzman, who was a big part of the A’s three straight championships and holds the record for most wins by a Jewish pitcher (174).

2:05	Jay Jaffe: I’m thinking about whether I can pull off a Herzog tribute in a timely fashion.

The Astros have dominated the American League West in recent years, winning three straight division titles and six out of the past seven, and getting at least as far as the American League Championship in each of those years. Their quest to extend that run is off to a rocky start, however. Despite taking two out of three from the Rangers this weekend in Houston, they own the league’s second-worst record thus far at 6-11, ahead of only the White Sox (2-13).

Even with the series win over the Rangers — whom they’ve now beaten in four out of seven games while going 2-8 against their other opponents — the Astros are off to their worst start since 2016, when they went 5-12. Notably, that season was the last one in which they missed the playoffs. Their 4-11 record through Friday was their worst through 15 games since 2013, the year they lost a franchise-record 111 games. That said, this is their fifth straight season below .500 at this juncture:

On the heels of a 101-loss season and a trade of Dylan Cease, it was quite apparent that the White Sox would be bad this year. So far, however, they’ve been even worse than that, losing 10 of their first 12 games to become the first AL team whose Playoff Odds have reached zero. Adding to that insult, they’ve already lost Eloy Jiménez, Luis Robert Jr., and Yoán Moncada — the three players who projected to be their most valuable — to injuries, sadly an all-too-common occurrence when it comes to each of them. It’s going to be a long season on the South Side.

The most severe of the injuries is that of Moncada, and woof, it not only looked bad but it may mark the end of his run with the White Sox, one that has certainly contained its share of highs and lows. While running out a grounder in the second inning of Tuesday’s game against the Guardians, he suddenly started limping about halfway down the line, then stumbled and crumpled to the ground before reaching first base, writhing in agony before being tended to by head athletic trainer James Kruk. “When I was running down the line, it felt like something broke. Honestly, that was the worst pain I’ve felt in my career,” Moncada told reporters via an interpreter on Wednesday.

Moncada was diagnosed with a strained left adductor, one of the muscles of the inner thigh, and yes, this will be a recurring theme. You don’t have to believe in jinxes to cringe at the fact that in the pregame media session before Moncada’s injury, manager Pedro Grifol told reporters that the 28-year-old third baseman had been dealing with a nagging hip/adductor injury for three or four days, adding, “He’s doing a really good job maintaining it.” Thus a minor injury has become a major one; the team announced that Moncada’s estimated recovery time is three to six months. In a best-case scenario, that would place his return around the start of the second half, while in a worst-case one, he might not make it back onto the field again this season.

Moncada is already coming off a pair of injury-wracked seasons that took a significant toll on his performance. After hitting for a 120 wRC+ with 3.7 WAR in 144 games in 2021, he slipped to a 76 wRC+ and 0.8 WAR in 104 games in ’22, missing five weeks due to an oblique strain and then 10 days for strains in each hamstring. He rebounded slightly in 2023, hitting .260/.305/.425 (98 wRC+) with 1.1 WAR, but still played just 92 games, missing over 10 weeks due to a pair of IL stints for lower back inflammation. He was off to a good start this season, hitting .282/.364/.410 (127 wRC+) while showing improved plate discipline through his first 44 plate appearances.

He is now in the final guaranteed season of the five-year, $70 million extension he signed in March 2020, making $24 million this year with a $25 million club option and $5 million buyout for 2025. Given the trends of his performance and Chicago’s payroll — which declined from $193 million in 2022 to $177 million to ’23 to $148 million this season as both the old and new regimes have stripped the roster for parts — it’s unlikely the team would have picked up his option. More likely, general manager Chris Getz would have looked to trade him this summer in an effort to fortify a farm system that got a shot in the arm last year, rising from 27th in projected future value in the spring to 12th later in the season.

Grifol said the team will rotate among a trio of players to fill in for Moncada, with 29-year-old lefty Nicky Lopez, 26-year-old lefty Braden Shewmake, and 24-year-old righty Lenyn Sosa all in the mix. None of them has hit a lick at the major league level, with Lopez — who has started eight games at second base and one at shortstop so far this year — the best of the bunch with a career 72 wRC+ across more than 1,900 PA; Sosa owns a 43 wRC+ through 224 PA, while Shewmake has a 50 wRC+, but only 25 PA so far. Each of them is a huge step down from Moncada, to say the least.

Robert isn’t expected to be out as long as Moncada, but his absence is depriving the White Sox of their lone All-Star from last year and their most dynamic player. The 26-year-old center fielder left Chicago’s April 5 game after injuring himself running out a double, and was diagnosed with a Grade-2 flexor strain in his right hip, the same one in which he suffered a Grade-3 strain in 2021. He missed about three and a half months that time, but this time around he’s only anticipated to be out six to eight weeks, with “only” doing a lot of work here.

The shame of it is that Roberts is coming off the closest thing he’s had to a full season in a while. His 145 games played last year was the highest total of his four major league seasons, topping his 98 games from 2022, when he made trips to the IL for COVID-19, blurred vision, and a wrist sprain; the only other time he played at least 100 games in a season was 2019, when he tallied 122 while rocketing through three levels of the minors. Even as the team collapsed around him last season, he put together an outstanding campaign, hitting 38 homers and stealing 20 bases while hitting .264/.315/.542 (128 wRC+) with 4.9 WAR. His slugging percentage and home runs both placed third in the American League, his wRC+ and WAR, eighth.

Robert was hitting just .214/.241/.500 at the time of his injury, with a two-homer, three-hit, four-RBI game against the Tigers on March 30 accounting for the bulk of his contributions. Thus far in Robert’s absence, Grifol has shifted his right field platoon over to center. That pairing — 26-year-old lefty Dominic Fletcher and 35-year-old righty Kevin Pillar — along with various other players in smaller roles placed the White Sox 28th in the right field version of our preseason positional power rankings. Meanwhile, Robert drove their no. 5 ranking among center fielders, but with his playing time reduced, he and his replacements have dropped to 12th in our Depth Charts. Somebody ought to put up a warning sign: “Beware of Falling Projections.”

As for Jiménez, he didn’t even make it to April, or to a spot in the outfield, before getting hurt. In the season’s third game, on March 31, the 27-year-old slugger strained an adductor in his left leg while running out an infield grounder and left the game. This marks his fourth straight season with a trip to the IL; in 2021 he missed four months due to a torn pectoral tendon, in ’22 he lost two and a half months to a torn tendon in his right knee, and in ’23 he was shelved 10 days for a left hamstring strain, and then three weeks for an appendectomy. Jiménez still managed to play 120 games last year, his highest total since his 2019 rookie season, but through his first five years, he played in only about 62% of Chicago’s games.

In the wake of last year’s early-season injuries, the White Sox used Jiménez in right field in just 14 games and DHed him 105 times. Keeping him off the grass is probably preferable given not only his fragile state but his defensive metrics (-22 RAA, -18 DRS, -9.8 UZR in 2066.2 career innings). That said, a DH-only role places a lot more pressure on him to hit in order to be valuable, and last year’s .272/.317/.441 (104 wRC+) translated to just 0.5 WAR, which doesn’t cut it. The good news is that Jiménez is on the mend, and could possibly return this weekend. In his absence, Gavin Sheets has gotten hot, batting .333/.455/.704 through 33 PA but [checks notes] none of our projections suggest he can maintain that.

In our preseason projections, Robert (4.0 WAR), Moncada (2.4), and Jiménez (1.9) occupied the team’s top three spots, with Andrew Vaughn (1.6) and Andrew Benintendi (1.5) the only other position players above 1.0. In other words, without this trio the Sox don’t have a single player who projects to be average or better in the lineup. These outages and this miserable start — which includes the lowest-scoring offense in the majors, at 2.42 runs per game — have dropped their already-abysmal win projection from 66.3 as of Opening Day to 60.8. With the possible exception of the days that Garrett Crochet starts — he’s got a 2.00 ERA and 2.50 FIP through three turns — this is going to be an unwatchable team at least until Robert gets back.

We’re two weeks into the 2024 season — Seoul Series excepted — so it’s difficult to take any hot start too seriously. Still, it’s a surprise that the Pirates entered Thursday with the National League’s highest winning percentage (.750, on the back of a 9-3 record), despite losing to the Tigers 5-3 on Tuesday afternoon in Pittsburgh. Since this isn’t the kind of condition that has tended to prevail after April in recent years, we’ll zoom in for a closer look.

The Pirates entered 2024 having finished below .500 in five straight seasons and seven out of the past eight, with an 82-79 record in 2018 constituting the lone exception; last year’s 76-86 record was their best since then, a 14-win improvement over 2022. While they did not have a particularly auspicious winter, they didn’t sit still, with general manager Ben Cherington signing half a dozen players — including four former All-Stars (Aroldis Chapman, Yasmani Grandal, Martín Pérez, and Andrew McCutchen, the last of them re-upping) and a Gold Glove winner (Michael A. Taylor) — to one-year contracts worth anywhere from $2.5 million to $10 million, with a couple notable minor league deals as well (Domingo Germán and Eric Lauer). Cherington also made a handful of trades, most notably adding Marco Gonzales and Edward Olivares. The team’s biggest move was inking top starter Mitch Keller to a five-year, $77 million extension that suggests he’ll outlast all of the newcomers. Read the rest of this entry »

Tyler O’Neill didn’t take long to adapt to a new team. Traded to the Red Sox in December after spending six years with the Cardinals, O’Neill claimed sole possession of a major league record by homering on Opening Day for the fifth straight season. As we approach the two-week mark of the season — yes, it’s early — he finds himself atop major leaderboards and has helped Boston get off to a 7-4 start.

On Tuesday at Fenway Park, O’Neill launched a towering solo shot over the Green Monster off Orioles ace Corbin Burnes to put the Red Sox up 1-0 in the first inning:

The Statcast-estimated distance of 413 feet made that O’Neill’s longest of this season so far. It was his sixth homer, momentarily moving him out of a tie with Mookie Betts, Marcell Ozuna, and Mike Trout, though Trout countered with his sixth later on Tuesday night. Nonetheless, O’Neill has matched Fred Lynn’s hot 1979 start for the most homers by a Red Sox player in the team’s first 11 games of a season, doing so while making just nine starts and a pinch-hitting appearance. By comparison, last season O’Neill didn’t hit his sixth home run until August 11, and finished with just nine in 72 games.

O’Neill began the season by homering off Mariners reliever Cody Bolton on Opening Day in Seattle. In doing so, he broke a tie with Yogi Berra (1955–58), Gary Carter (1977–80) and Todd Hundley (1994–97) for the most consecutive Opening Day games with a home run. (And you thought you were glad baseball was back!) He closed out the Seattle series with a homer off Bryce Miller on March 31, took the Angels’ Griffin Canning and José Soriano deep on April 5, then added a dinger against Chase Silseth on April 7.

Unfortunately for the Red Sox, O’Neill’s blast on Tuesday was their only run of the day; they lost 7-1. And oddly enough, the 28-year-old left fielder hasn’t driven in anyone else despite his six home runs, which is more a commentary on his teammates than his own failings; he’s 1-for-3 with a pair of walks with runners in scoring position. Regardless of his RBI total, he’s swinging a very hot bat overall, hitting .344/.488/.906. It’s not every day you’re miles ahead of two future Hall of Famers for the major league lead in key categories, so we’ll note that his slugging percentage is 126 points ahead of the second-ranked Trout, and his 276 wRC+ is 32 points ahead of the second-ranked Betts. Meanwhile his on-base percentage merely leads the American League.

Of course, O’Neill has played just 10 games, the first nine of them against the Mariners, A’s, and Angels — all on the road — and there’s only so much we can take from that, but the number one thing is that he’s healthy, and that’s a big one, because save for his monster 2021 season and his brawny physique (“listed at 5-foot-11 and 200 pounds, of which about 198 pounds is biceps and quads,” wrote Michael Baumann), injuries have largely defined his career.

Drafted by the Mariners out of a British Columbia high school in the third round in 2013, O’Neill became a Cardinal in the Marco Gonzales trade four years later. He debuted in the majors on April 19, 2018, but spent much of that season and the next one bouncing back and forth between Triple-A and the majors, with five (!) trips to the injured list thrown in for good measure. After spending all of 2020 in the majors and on the active roster — and even winning his first Gold Glove, but hitting a miserable .173/.261/.360 — he finally got something close to a full-length season under his belt in 2021, hitting .286/.352/560 (143 wRC+) with 34 homers, 15 steals, and 5.3 WAR in just 136 games, but accompanying that with two more trips to the IL. He added a second Gold Glove that year, and finished eighth in the NL MVP voting, but since then he hasn’t come close to replicating that season, with injuries limiting him to just 168 games, 23 homers, a 98 wRC+ and 2.0 WAR across 2022–23, another two-year span that included five trips to the IL:

Thus the 28-year-old O’Neill entered this season having played more than 100 games in a major league season just once, and more than 72 just twice. Between his injuries, a crowded field of alternatives, his increasing price tag, and a spat with manager Oliver Marmol — who publicly questioned O’Neill’s effort running the bases during a heavy rain last April 4 in St. Louis, calling his effort “unacceptable” — O’Neill fell out of favor in St. Louis. On December 8, the Cardinals traded the pending free agent to the Red Sox in exchange for a pair of righty relievers, Nick Robertson and Victor Santos.

So far, the change of scenery seems to agree with him, though it’s worth noting that Tuesday’s game was his first at Fenway with the Red Sox. One game, one homer? That’s a pretty good rate!

In light of O’Neill’s long history of leg woes, it’s worth pointing out that as of now he’s hitting the ball harder than in the past two seasons. I present these stats while acknowledging that we don’t have enough data to draw strong conclusions about what’s happening yet; this is as much about his decline from 2021 as it is his torrid start:

Bear in mind that, as Baseball Prospectus’ Russell Carlton has noted, exit velocity stabilizes around 40 batted ball events, and barrel rate at 50 BBE, while groundball, fly ball, and hard-hit rates do so at 80 BBE. Within this small sample, this year’s exit velo and barrel rate at least look more like 2021 than ’22 or ’23. On a rolling basis of 25 plate appearances, both his xSLG and xwOBA show that his season-opening hot streak resembles only two or three stretches from the past two seasons, while he had a handful of such stretches in 2021:

The other thing to note about O’Neill is how much he’s tightened his approach so far. He’s a guy with a lot of swing-and-miss in his game, so much so that even as he ranked no. 61 on our Top 100 Prospects list in 2018, he had 30/40 grades (present/future) on his hit tool, and from 2018–23, he struck out 30% of the time, seventh among hitters with at least 1,500 PA in that span. Production-wise, he’s near the upper end among guys with strikeout rates in that neighborhood; of the hitters with the 30 highest strikeout rates over at least 1,000 PA within that span — everybody from 28.8% up — his 111 wRC+ ranks fourth, behind only Luke Voit (123), Giancarlo Stanton (122), and Teoscar Hernández (117).

Entering this season, O’Neill had swung at 72.5% of pitches within the strike zone, including 71% last year; so far this year, he’s cut that down to 50.8%. Similarly, his overall swing rate of 48.1% entering this year (44.9% last year) is down to 36%. His swinging strike rate of 15.4% (11.2% last year) is way down to 6.4%, and his strikeout rate, which was 25.2% last year, is at 19.5%. Mind you, none of these stats have stabilized — swing rate takes about 50 PA (he’s at 41) and strikeout rate requires roughly 60 PA — but those are at least promising trends.

We’re obviously still early enough in the season that any trend could be a mirage, a two-week heater or skid that might not merit closer scrutiny if it were located in mid-June or the dog days of August. Still, when combined with his hot streak, the health and change-of-scenery aspects of O’Neill’s situation are at least worth keeping an eye on. He’s not going to continue slugging .906, but for a team whose outfielders entered this season ranking 22nd in the majors with a combined 96 wRC+ since 2020 — i.e., the post-Betts era — this counts as a welcome development.

If last week’s news that Eury Pérez would need Tommy John surgery was bad, Saturday was a whole lot worse. Within a span of five hours, the baseball world learned that the Guardians’ Shane Bieber, the Yankees’ Jonathan Loáisiga, and the Braves’ Spencer Strider have all incurred significant damage to their ulnar collateral ligaments, with Bieber headed for Tommy John surgery, Loáisiga set to undergo season-ending surgery as well, and Strider headed to see Dr. Keith Meister, the orthopedic surgeon who will perform the surgeries of the other two.

The losses of those pitchers is a triple bummer, not just for them and their respective teams — each of which leads its division, incidentally — and fans, but for the sport in general. Underscoring the seriousness of the issue, by the end of Saturday both the players’ union and Major League Baseball traded volleys regarding the impact of the introduction of the pitch clock on pitcher injuries in general.

Bieber, a two-time All-Star, won the AL Cy Young award and the pitchers’ Triple Crown during the pandemic-shortened 2020 season, but missed significant time in two out of the past three years due to injuries. In 2021 he was limited to 16 starts due to a strain of his subscapularis, the largest of the four muscles that make up the rotator cuff, and last year he made just 21 starts, missing 10 weeks due to elbow inflammation. He had pitched very well this season, with a pair of scoreless six-inning outings, each totaling just 83 pitches. He struck out 11 A’s in Oakland on Opening Day and then nine Mariners (without a single walk) in Seattle on April 2.

Bieber experienced more soreness than usual while recovering from the Opening Day start, but the 29-year-old righty and the team decided to proceed without extra rest, according to MLB.com’s Mandy Bell, who wrote, “Bieber wanted to see if he could push through this, considering he hadn’t felt any pain in Spring Training.”

The discomfort persisted during Bieber’s second start, after which the team ordered additional testing, “which revealed the injury to the same ligament he had problems with last year,” wrote Bell. If I’m not mistaken, that last bit of information is new, as previous reports of last year’s injury did not specify as to the inflammation’s cause. “He really put in a ton of work this winter and throughout spring training, and we all felt he was on a good path to stay healthy and contribute for the balance of the season,” said president of baseball operations Chris Antonetti on a Zoom call with reporters. Antonetti additionally lauded the pitcher’s “sheer toughness and grit” in maintaining a high level of performance, while manager Stephen Vogt sounded a similar note in saying, “The amount of work that this guy’s put in over the last few years, the things that he’s pitched through, that’s a testament to who he is.” But those supportive statements raise the question of whether this juncture could have been avoided had Bieber taken a longer time to heal from the damage found last summer, as teammate Triston McKenzie did. Missing from that comparison, however, is information regarding the severity of the two pitchers’ tears, details to which we’re not privy.

As a pending free agent, Bieber is in a tough spot, as he’ll enter the market under a cloud of uncertainty, likely cutting into a payday that’s ceiling has already been reduced by his previous outages. As for the Guardians, their remaining rotation looks so shaky that it ranks 27th in projected WAR via our Depth Charts, and their Playoff Odds have decreased since Opening Day (from 33.5% to 32%) despite the 7-2 start that has put them atop the AL Central.

The 26-year-old McKenzie, who was limited to four starts last season by a teres major strain as well as his UCL sprain, was rocked for five runs (four earned) in 3.1 innings in his first outing on Monday against the Mariners. His four-seam fastball averaged just 90.5 mph, down two miles per hour from 2022, when he was fully healthy. Carlos Carrasco, now 37, is coming off a 6.80 ERA in 20 starts with the Mets. Both Tanner Bibee, a 25-year-old righty, and Logan Allen, a 25-year-old lefty, are coming off strong rookie seasons and have pitched well in the early going, but Gavin Williams, a 24-year-old righty who posted a 3.29 ERA and 4.05 FIP in 16 starts as a rookie last year, began the year on the injured list due to elbow inflammation himself and has not yet been cleared to begin a rehab assignment. Out on rehab assignments are 25-year-old righty Xzavion Curry, and 32-year-old righty Ben Lively, both of whom were sidelined by a respiratory virus during spring training. Both split time between starting and relieving last year but turned in ERAs and FIPs over 5.00, the former with the Guardians, the latter with the Reds. Joey Cantillo, their top upper level pitching prospect, is out for 8-10 weeks with a left hamstring strain.

As for the 29-year-old Loáisiga, he’s been so beset by injuries throughout his career — including Tommy John surgery in 2016 — that he’s thrown 50 innings in a major league season just once (70.2 in 2021) and has totaled 50 innings between the majors and minors just two other times, in 2018 (80.2, mostly as a starter) and ’22 (50 exactly). He was limited to 17.2 innings last year due to in-season surgery to remove a bone spur in his elbow, then less than five weeks after returning was sidelined by inflammation in the joint. Three appearances into this season, he was diagnosed with a flexor strain and a partially torn UCL, though based upon the reporting, it sounds as though he’s a candidate for the internal brace procedure that requires less recovery time. Via MLB.com’s Bryan Hoch:

Meister’s initial reading of an MRI performed on Thursday in New York suggests that Loáisiga could avoid undergoing what would be his second career Tommy John surgery, with the estimated recovery for Meister’s preferred procedure spanning 10-12 months.

It was Dr. Jeffrey Dugas who invented the internal brace procedure, in which collagen-coated FiberTape suture is used to anchor the damaged UCL, speeding up recovery by eliminating the time needed for a tendon to transform into a ligament. Meister has pioneered the combining of traditional Tommy John surgery with the use of the internal brace; when it’s referred to at all as different from traditional Tommy John, it’s as a “hybrid” procedure. It’s what Jacob deGrom had last year (with Meister performing the procedure), and it sounds like what Shohei Ohtani (who was operated on by Dr. Neal ElAttrache) underwent last fall as well. In a March 7 piece in the Dallas Morning News, Meister said he’s done over 300 hybrid surgeries since 2018, which suggests the distinctions are being blurred when we track such surgeries.

Regardless of the type of surgery, Loáisiga’s absence has dealt a significant blow to a bullpen that already looked considerably less formidable than in years past. After ranking third in the majors with 7.2 WAR in 2021 and fifth with 5.9 in ’22, the unit slipped to 16th (4.2 WAR) last year, and ranked 19th in our preseason positional power rankings; Yankees relievers are now down to 22nd. Beyond closer Clay Holmes and setup man Ian Hamilton, it’s a largely unfamiliar if not untested cast, featuring a pair of ex-Dodger southpaws (Victor González and Caleb Ferguson), a trio of righties with career ERAs above 5.00 (Nick Burdi, Dennis Santana, and Luke Weaver). Moreover, the 31-year-old Burdi has never thrown more than 8.2 innings in a major league season, and another righty, Jake Cousins, has just 55.2 career innings, 30 of which came in 2021. Maybe pitching coach Matt Blake and company can find some diamonds in the rough, and maybe the likes of Tommy Kahnle, Lou Trivino, and Scott Effross can recover from their various injuries and surgeries to provide help later this season, but this is a clear weakness for a team off to an 8-2 start.

Strider is coming off a stellar season — his first full one in the rotation — in which he led the NL in strikeouts (281), strikeout rate (36.5%), FIP (2.85), and wins (20) while making his first All-Star team and placing fourth in the Cy Young voting. After throwing five innings of two-run ball while striking out eight on Opening Day against the Phillies, he surrendered five runs in four innings against the Diamondbacks on Friday, then complained about elbow discomfort afterwards. The Braves sent the 25-year-old righty for an MRI, after which the team’s official Twitter account shared the bad news:

Spencer Strider today underwent an MRI that revealed damage to the ulnar collateral ligament in his right elbow. He will be further evaluated by Dr. Keith Meister in Arlington, TX, at a date yet to be determined.

Strider already underwent his first Tommy John surgery as a sophomore at Clemson in 2019. While it’s not a guarantee yet that he’ll need a second one, the Braves sound resigned to it, with manager Brian Snitker telling reporters, “The good news is he’s going to get whatever it is fixed and come back and continue to have a really good career.” Strider at least has security even if he’s never the same, having already signed a six-year, $75 million extension in October 2022, the largest pre-arbitration extension ever for a pitcher.

The Braves will certainly feel his loss. Of their remaining starters, 40-year-old righty Charlie Morton has been reliable and durable, taking the ball at least 30 times in each of the past three seasons, but 30-year-old lefty Max Fried was limited to 14 starts last year by hamstring and forearm strains as well as a blister on his index finger. Lefty Chris Sale, 35, missed 10 weeks last year due to a stress fracture in his scapula, which limited him to just 20 starts — nine more than he totaled over the three prior seasons combined while missing time due to Tommy John surgery and a stress fracture in his rib. Thirty-year-old righty Reynaldo López is starting again after spending nearly all of the past two seasons as a reliever. Twenty-four-year-old righty Bryce Elder was an All-Star last season but was optioned to Triple-A Gwinnett to start the year after a second-half fade and a rough spring. Prospects AJ Smith-Shawver, a 21-year-old righty, and Dylan Dodd, a 25-year-old lefty, are also at Gwinnett; the former was no. 63 on our Top 100 Prospects list. Ian Anderson and Huascar Ynoa are both recovering from Tommy John, the former from April 2023 and the latter from September ’22. One way or another, the Braves will cobble things together, but they can’t afford too much else to go wrong.

Saturday’s flood of UCL-related headlines followed a week that featured the bad news about Pérez as well as Tommy John surgery for A’s reliever Trevor Gott. On Saturday evening, Major League Baseball Players Association executive director Tony Clark released a statement that targeted the pitch clock as the culprit for so many arm injuries:

Despite unanimous player opposition and significant concerns regarding health and safety, the Commissioner’s Office reduced the length of the pitch clock last December, just one season removed from imposing the most significant rule change in decades.

Since then, our concerns about the health impacts of reduced recovery time have only intensified.

The league’s unwillingness thus far to acknowledge or study the effects of these profound changes is an unprecedented threat to our game and its most valuable asset – the players.

The league quickly countered:

This statement ignores the empirical evidence and much more significant long-term trend, over multiple decades, of velocity and spin increases that are highly correlated with arm injuries. Nobody wants to see pitchers get hurt in this game, which is why MLB is currently undergoing a significant comprehensive research study into the causes of this long-term increase, interviewing prominent medical experts across baseball which to date has been consistent with an independent analysis by Johns Hopkins University that found no evidence to support that the introduction of the pitch clock has increased injuries. In fact, JHU found no evidence that pitchers who worked quickly in 2023 were more likely to sustain an injury than those who worked less quickly on average. JHU also found no evidence that pitchers who sped up their pace were more likely to sustain an injury than those who did not.

Particularly in the wake of the recent in-house drama that resulted in a challenge to his leadership of the union, Clark’s statement is probably better understood as a political one than a scientific one. The majority of the players he represents are pitchers, and they may be looking for a target for their anger and fears regarding increased injury rates. It’s worth noting that those players — or at least the major leaguers who were part of the union when the most recent Collective Bargaining Agreement was hammered out in March 2022 — agreed to the structure of the Joint Competition Committee, which contains six owners, four players, and one umpire; “unanimous” is more likely referring to those four players rather than the 6,000-plus the MLBPA now represents.

As the league’s statement notes, and as The Ringer’s Ben Lindbergh reported last week, MLB has been conducting a comprehensive study of pitcher injuries since October, and once it’s done (perhaps later this year) “intends to form a task force that will make recommendations for protecting pitchers.” The group will “try to come up with some solutions and implement some solutions,” according to Dr. Glenn Fleisig, who as the biomechanics research director at the American Sports Medicine Institute and as an injury research adviser for MLB is one of the experts being consulted.

To varying degrees, Fleisig, Meister, ElAttrache and the now-retired Dr. James Andrews have all publicly pointed to the extra stress on arms induced by the quest for increased velocity, increased spin, and maximum effort as the primary causes of increased pitcher injury rates, a quest that starts in youth baseball, while players’ bodies are still developing. Leaguewide data from the pitch-tracking era particularly points to the way major league players and teams have chased velocity:

The average four-seam fastball velocity has consistently crept up by 0.1–0.2 mph per year, with a couple jumps of 0.3 mph; while it’s down thus far this year, velocities tend to increase once the weather warms up. The percentage of four-seamers 97 mph or higher more than tripled from 2008–23, and shot up 54% from 2019–23. The average spin rate for four-seamers increased by only about 2% from 2015 — the first year of Statcast — to ’23, and while the average spin rate for all breaking pitches combined increased by about 12% in that span, most of that jump was in the first two seasons. Those spin rates have been pretty consistent since then, but the total volume of breaking balls has increased.

The idea that the pitch clock could be contributing by making pitchers dial up to maximum intensity with less time to recover between pitches has intuitive appeal, but injury rates had already risen before the clock’s introduction last year. As Baseball Prospectus’ Derek Rhoads and Rob Mains noted, the total of 233 pitchers who landed on the injured list last year was about the same as in 2022 (226) and ’21 (243), up from ’19 (192). Likewise for the number of Tommy Johns as measured by year, starting with the day that pitchers and catchers report (as opposed to a calendar year): 28 for last season, compared to 26 for 2022, 31 for ’21, 27 for ’20, and 16 for ’19. In a study published last June, my colleague Dan Szymborski found no meaningful relationship in injury rates with regards to the pitchers whose pace increased the most from 2022 to ’23, at least to that point. The Hopkins study that MLB cited has yet to be published, though it’s hard to believe that the league hasn’t shared its preliminary findings with the union. Notably, Clark did not point to any study that produced a result that reflected his constituency’s concerns.

On the subject of velocity, the link between Strider’s high velo and the propensity for such pitchers to require Tommy John is hard to miss. Of the top 15 starting pitchers in terms of average four-seam fastball velocity from 2021–23, 10 have undergone at least one surgery to repair their UCLs, and Strider is in danger of becoming the fourth to need a second:

Some of those pitchers have had little trouble recovering and maintaining their elite velocities after their first such surgery, but as the sagas of deGrom and Ohtani illustrate, that hardly makes them immune from needing a second procedure. As the big contracts of so many of the pitchers above remind us, velocity gets pitchers paid, and so discouraging them from throwing at maximum effort with such frequency may be a tough sell, particularly when the next guy is willing to do so, damn the consequences.

This is all one big, thorny mess that won’t be solved overnight. The sad fact is that dozens or even hundreds more pitchers will be injured before we see if MLB can introduce meaningful steps to curb injury rates. In the meantime, teams will just turn to the next man up — and if he gets hurt, the next man up after him — to get by.
