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 »

Shelby Miller was already evolving when I talked to him for FanGraphs prior to the 2016 season. As addressed in that interview, the right-hander had markedly altered his pitch usage in 2015, a season in which he logged a 3.02 ERA over 205 1/3 innings in his lone campaign with the Atlanta Braves. Little could he have imagined how many more changes were coming.

Originally drafted 19th overall by the Cardinals out of a Texas high school, Miller spent parts of three seasons with St. Louis, placing third in the NL Rookie of the Year voting in 2013, before he was the main return for Atlanta in the Jason Heyward trade in November of 2014. When we spoke for that earlier post, he was ramping up for his first season with the Arizona Diamondbacks, who a few months earlier had acquired him in the Dansby Swanson trade.

Now, eight organizations later (11 total for those keeping score at home), Miller is 33 and recording high-leverage outs with the Detroit Tigers, who in December signed him to a one-year, $3.25 million deal with a club option for 2025. And not only have his repertoire and usage continued to evolve over the years — last season with the Los Angeles Dodgers was especially notable — but they’re currently in flux. The mix that Miller has employed this season over five relief outings comprising seven scoreless innings may not be what you see the next time he takes the mound. More on that in a moment.

Lance Lynn is my favorite player in baseball; I find it easier to just admit this up front and let readers view my work through that lens, instead of going through the trouble of trying to obfuscate this very obvious truth.

One of the things that drew me to the big man in the first place was his reliability. Lynn had been many things over his long and venerable big league career: A four-seam specialist, a sinkerballer, an ace, an innings eater, an underrated gem, a star, a national hero. But he’d never been bad before.

In 2023, Lynn still threw 183 2/3 innings, but he gave up about 183 2/3 home runs over that span. Not really, but the actual number — 44 — was so high I invoked the late Jose Lima when I wrote up Lynn’s signing in November. On a scale from zero to things you don’t want, it’s not what you want.

This time last year, baseball discussion was focused on one thing: steals. There they were, in great huge quantities for the first time in decades. With disengagements and therefore pickoff throws limited, men on base ran wild. They were successful at a huge clip, to boot. By year’s end, last season’s 3,503 stolen bases were the most in any campaign of the 21st century.

The wildest part about this statistic is that it felt like there still weren’t enough steals. Runners were successful at an 80.2% clip last year. That’s quite a bit higher than the breakeven rate of success, which bounces around the 75% mark based on game state; after all, not all steals are created equal. Russell Carleton dug into the data and noted that runners didn’t change their aggression at all until they had seen at least one pickoff throw.

Meanwhile, their success rate on the instances where the pitcher *didn’t* throw over ballooned to nearly 83%. You didn’t have to be a rocket scientist to figure out where this was going. In 2024, the thinking went, runners would have more experience with the new rules, and therefore would start taking off more frequently, pickoff throw or no pickoff throw. Naturally, new rules take a while to adjust to, but this adjustment seemed pretty likely to happen.

So far, though, it hasn’t. Here are stolen base attempts per game over the last six years. I threw in some old years for scale, but really I’m only concerned with 2023 and 2024:

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.

How would the Norfolk Tides do if they played in the majors? That might sound like an odd question, but it’s one that I’ve been asked four times in the last week. It even came up on Reddit. What’s driving this curiosity isn’t a sudden surge in rabid Tides fandom, but rather the heavy concentration of offensive talent the Orioles have in Norfolk, which until today, included one of the favorites for AL Rookie of the Year, Jackson Holliday. And since I’m one of a handful people with the exact tools of nerdery to answer this query, I couldn’t let it go unanswered. Read the rest of this entry »

I don’t really have strong opinions about the AL Central this year, either aesthetically or competitively. I picked the Tigers to win the division because I like their young pitchers, I had to pick someone, and I didn’t want to just choose the same 12 teams that made the playoffs last year. But if the Twins or Guardians, or even the Royals finished first, I wouldn’t be unduly surprised.

Mostly, I want to go the entire season without having to watch Byron Buxton leave the field on a gurney, for much the same reason I’d like to visit the Grand Canyon before I die. I’ve never actually seen it, but I’ve heard it’s wonderful. Apart from that, I’ve got an open mind.

Even so, the first two weeks of the season have brought some remarkable results. Stephen Vogt now has a better winning percentage than any manager in MLB history (minimum 10 games), as the Guardians jumped out to an 8-3 start. The Tigers and Royals are right behind, and Kansas City has had one of the best rotations in the league so far.

These three teams have one thing in common, other than their division: They’ve all played the White Sox. Read the rest of this entry »

A month after signing starting pitcher Brayan Bello to a six-year extension, the Boston Red Sox are at it again, this time extending rookie center fielder Ceddanne Rafaela on an eight-year deal worth $50 million. If Rafaela sticks in the majors long enough this season to earn a year of service time, this extension will prolong his free agent eligibility for two years; either way, he’ll be paid a guaranteed salary through the 2031 season.

How you feel about Rafaela comes down to just what you think about his defense. Eric Longenhagen and Tess Taruskin rated Rafaela as the only prospect on THE BOARD last year with a 70 present value for defense and the only one with a future value of 80. They were hardly alone in their praise for his glove, either, as other outlets such as Baseball Prospectus and MLB Pipeline also gave complimentary reviews to his leathercraft.

While prospect writers have occasionally missed on the eventual defensive performance of prospects – Gregory Polanco comes to mind – Rafaela certainly hasn’t shown anything in his limited time in the majors that refutes these views. Measuring minor league defense, as opposed to viewing it, is fraught with obvious peril, but the defensive estimates that ZiPS uses for minor leaguers also love his glove. ZiPS uses a Total Zone-esque measure from Gameday hit locations, similar to Sean Smith’s methodology from nearly 15 years ago. Yes, we’d prefer to have something like OAA or DRS or even UZR for minor leaguers publicly available, but we don’t, so we have to generally be more conservative about conclusions drawn from the data. But for what it’s worth, these estimates, which I call zDEF, had Rafaela as an elite defensive center fielder in the minors in 2023.

Incidentally, zDEF had Rafaela at +3 as a shortstop total for his minor league career, so if the circumstances warranted it, it wouldn’t necessarily be the craziest thing to see him follow in the footsteps of another former Red Sox prospect, Mookie Betts, and move back to shortstop at some point, though that certainly is not why Boston signed Rafaela long term.

Let’s run the eight-year ZiPS for Rafaela.

All told, ZiPS would happily offer him an eight-year, $67 million — $17 million more than what the Red Sox gave him.

One thing to take into consideration: So long as Rafaela’s glove is excellent, he doesn’t need to take a big offensive step forward to be worth his contract. ZiPS has Rafaela hitting for a skosh more power, enough to get his OPS+ and wRC+ into the 100 range during his peak years, but not sufficient to make him a superstar. As a result, his projections keep him in the solidly above-average territory – he’ll likely have an All-Star appearance or two during an up year – but comfortably below star status. These offensive numbers make him slightly better offensively than the inevitable comp given for him, Jackie Bradley Jr., who put up a 93 OPS+ over parts of eight seasons in Boston and was a few runs better defensively than Rafaela’s projections. Suffice it to say, if ZiPS’s natural conservatism with minor league defensive numbers ends up lowballing Rafaela, he’d be a steal at this price and put up WAR numbers in the range of Kevin Kiermaier’s best years.

As an offensive player, Rafaela remains a work in progress. In nine games this season entering Tuesday, he’s hitting .233/.286/.400 with two triples and an 85 wRC+. He’s actually gotten better at making contact, going from a 69% contact rate at Triple-A last year to 73% in the majors so far. Admittedly, this improvement has come in a small sample — he’s made just 124 big league plate appearances combined between his 2023 late-season debut (72.1% contact in 89 PA) and this year (76.3% in his 35 PA) — but it is still encouraging.

That said, he remains far too aggressive at the plate, especially when you consider his specific profile as a hitter. Unlike his teammate Rafael Devers, who also swings at a pretty high rate of pitches out of the zone, Rafaela doesn’t hit the ball particularly hard; Devers has power to spare, so even though he doesn’t make as much hard contact on pitches out of the zone — his average exit velocity drops to 85.5 mph, down from 94.9 mph on in-zone pitches — he can still do damage. Rafaela doesn’t have that luxury. Instead, he is a speedster (ranking 28th in sprint speed this season among 202 qualified players) who plays his home games at Fenway Park, one of baseball’s best parks for batting average. He should be incentivized to have a more contact-oriented game than most other batters. His contact skills appear to be improving, but he won’t get the most out of his game if he keeps chasing pitches that’s he unlikely to hit.

The Betts trade and the departure of Xander Bogaerts are still, rightfully, pain points for Boston fans. But since then, the Red Sox seem to be making a better effort to retain the players they develop, first with the Devers extension in January 2023 and now with Bello and Rafaela. Ultimately, winning is the only thing that will make things better in Boston. Keeping Rafaela in town should be an important step toward that.

It’s been a hot start to the 2024 season for the Boston Red Sox. They started the season with a 10-game road trip to the West Coast and arrived home Monday at 7-3 after a four-game split in Seattle, a three-game sweep in what will likely be their final trip to play the A’s in Oakland, and a 2-1 series win over the Angels. While Boston hasn’t exactly met the highest of competition yet — this week’s home-opening series with Baltimore should be a serious test — the Sox entered Tuesday with the second-best run differential in the majors, at +26. Aside from the Trevor Story’s injury, which as Jon Becker explained yesterday is going to test Boston’s uninspiring middle infield depth, it’s been an encouraging first two weeks for Alex Cora’s club.

Somewhat unexpectedly, pitching has been the story of Boston’s early success, after the Red Sox redesigned their pitching infrastructure over the offseason. In this regard, two of the most important additions to the club are not current players but former big league pitchers: Craig Breslow, who replaced Chaim Bloom as the team’s chief baseball officer, and Andrew Bailey, the new pitching coach. After pitching as a reliever for 12 years in the majors, including parts of five seasons with the Red Sox, Breslow spent five years in the Cubs’ front office working to overhaul their pitching program. One of Breslow’s first moves was to hire Bailey, his former Red Sox teammate. Bailey, a two-time All-Star and the 2009 American League Rookie of the Year, came over from the Giants, where he held the same role and helped to develop the likes of Logan Webb, Kevin Gausman, and Carlos Rodón into some of baseball’s top pitchers recent years. Boston also hired Justin Willard to a role it titled “director of pitching.”

Entering Tuesday, Red Sox pitchers lead the majors with a 1.49 ERA, a 2.92 FIP, a 3.08 xFIP, 10.49 strikeouts per nine, and 2.4 WAR. Two times through the rotation, Tanner Houck hasn’t allowed a run, and Nick Pivetta, Kutter Crawford, and Garrett Whitlock have allowed one earned run each. The bullpen has supported this rotation capably, too — in 37.1 innings, Boston relievers rank second in baseball with 0.8 WAR, third with a 1.45 ERA and 3.40 xFIP, and fourth with a 3.18 FIP. All of this from a staff that features mostly the same members from a group that struggled last season. It’s too early to know for sure if 2024 will be any different, but this is an auspicious start.
