As far as ballplayers go, Chris Sale and Cal Quantrill don’t have a whole lot in common. Sale is an established star, with the resume and salary to prove it; Quantrill only recently completed his first full season as a starting pitcher. At his peak, Sale was the preeminent strikeout artist in baseball and arguably the best of all time; Quantrill has the lowest K-rate among qualified pitchers this season. Both have gone under the knife for Tommy John surgery, but while Quantrill has been the picture of health ever since, Sale has yet to return to his former glory.

This past Friday, these two dissimilar pitchers found themselves in the same boat when they landed on the injured list with shoulder inflammation, just days before their respective clubs were due to face off in a three-game set. Shoulder inflammation is a vague descriptor, and the prognosis for it can vary widely. Sometimes a pitcher will only miss a couple of starts to let the pain subside, but in a worst-case scenario, shoulder problems can lead to season-ending surgery. There is no reason to believe, as of yet, that either Sale or Quantrill will need to go the surgical route, but it also seems unlikely that either will return as soon as the minimum 15 days are up. Sale will undergo further testing and might not have a proper diagnosis until this weekend. Quantrill, meanwhile, has stopped throwing altogether. Read the rest of this entry »

It seems like all of our coverage of the 2023 Diamondbacks here at FanGraphs has focused on the pitching, and it’s not hard to see why. Zac Gallen has looked phenomenal (at times historically so), Madison Bumgarner was abominable (eventually too abominable to roster), and the D-backs have given some intriguing young arms the chance to prove their worth in the big league rotation.

Yet all that being so, the real story of the 2023 Diamondbacks has been the offense. They lead the National League in hitting and rank third with 257 runs scored. They’re fourth in OBP, fourth in slugging percentage, and fifth in wRC+. By and large, the pitching staff has performed as expected – Gallen good, MadBum bad, everyone else somewhere in between – but the offense has been more potent than anyone could have envisioned.

It’s been a team effort in Arizona; among the nine Diamondbacks hitters with at least 100 PA, seven have been above-average at the plate. Corbin Carroll is off to the races. Lourdes Gurriel Jr. has taken a massive step forward. Ketel Marte and Christian Walker have been predictably solid, while Gabriel Moreno and Pavin Smith are holding their own. Leading the way, however, has been none other than Geraldo Perdomo, who is pacing the club in OBP, wRC+, and WAR. What? Read the rest of this entry »

The Marlins were the subject of jokes aplenty this winter after they added two established second basemen, Luis Arraez and Jean Segura, to a roster that already featured multiple capable keystone defenders. Yet all jokes aside, Kim Ng’s unconventional method of roster construction has worked out quite well thus far. Arraez leads all primary second basemen with a 151 wRC+, and his defense is tolerable as long as he keeps hitting. Meanwhile, Jazz Chisholm Jr., though currently on the IL, has adjusted well to center field, and Jon Berti and Joey Wendle have been an excellent defensive tandem at shortstop.

However, the second baseman the Marlins signed to play third is struggling terribly. Segura is slashing .200/.268/.236 (the rare .200/.200/.200 batting line, also known as a Paul Janish), and he is one of only five qualified hitters without a home run (an achievement known as a Reggie Willits). His 43 wRC+ ranks last in baseball, as does his .231 wOBA and .504 OPS. The only qualified hitter with a lower WAR is José Abreu, who has had an additional five games in which to be dreadful. Segura’s only saving grace is that he has hit well in 15 high-leverage plate appearances (.385 AVG, 134 wRC+), but even so, his -1.31 WPA is the worst in the National League.

The last qualified batter to finish with a wRC+ below 45 was Clint Barmes, who posted a 38 wRC+ in 2006. Since then, only five other players have even finished below 50; typically, hitters either improve as the year goes on, or they don’t get enough playing time to qualify. As for the handful who lasted a full season with such a feeble bat, the only one to have been an above-average hitter throughout the rest of his career was Chris Davis of the Baltimore Orioles. His 46 wRC+ in 2017 was a huge step down from his career 117 wRC+ to that point. Read the rest of this entry »

Win Probability Added isn’t a great measure of true talent – it’s influenced by too many factors outside a player’s control – but ultimately, the best players tend to have the highest WPAs. Last season, AL MVP Aaron Judge led all position players in WPA, while NL MVP Paul Goldschmidt finished on top in the Senior Circuit. The year before, it was AL MVP Shohei Ohtani who finished first overall and NL MVP Bryce Harper who paced the National League. Even in the early days of the 2023 season, the WPA leaderboard is a veritable who’s who of superstars and MVP contenders. Yordan Alvarez leads all position players with 2.42 WPA, while Ronald Acuña Jr. leads the NL with 2.18. Following closely behind in the AL is Vladimir Guerrero Jr., with 2.12 WPA to his name.

After those three, only one other hitter has a WPA above 2.00 this year, and his name is rarely listed among the likes of Alvarez, Acuña, and Guerrero. In what will be his first full season, 27-year-old Jake Fraley has already notched 2.10 WPA for the Cincinnati Reds. Read the rest of this entry »

The 2023 season isn’t off to the best start for last year’s AL Cy Young finalists. Reigning winner Justin Verlander missed the first five weeks with a shoulder strain and now faces the unenviable task of rescuing an ailing Mets rotation. Runner-up Dylan Cease has had his moments but an equal number of surprisingly poor outings. Finally, third-place finisher Alek Manoah is struggling most of all. His ERA has doubled, his WAR is in the negatives, and his 1.28 K/BB ranks last among qualified major league pitchers.

Manoah’s slow start has been difficult to watch. Last season, at just 24 years old, he established himself as the ace of the Blue Jays’ staff, securing his first All-Star selection and earning the nod for Game One of the Wild Card Series. Six months later, he was awarded the Opening Day start, making him the youngest Opening Day starter in the American League. The analytics crowd (myself included) might have argued Kevin Gausman was the true no. 1 in Toronto, but the Blue Jays clearly chose Manoah, and it wasn’t hard to understand why: Read the rest of this entry »

Like a riddling Batman villain, the Red Sox entered the 2023 season draped in question marks. Much of the uncertainty surrounded their rotation, which was set to include injury-prone veterans Chris Sale, Corey Kluber, and James Paxton; perennial “breakout” candidate Nick Pivetta; and converted reliever/inexperienced starter Garrett Whitlock. Moreover, the Red Sox were heading into battle without their three most valuable defensive players from the year before. Christian Vázquez, Xander Bogaerts, and Trevor Story combined for 20 DRS and 28.8 DEF in Boston last season; the rest of the team produced -51 DRS and -40.8 DEF. Reese McGuire, Enrique Hernández, and Christian Arroyo had big shoes to fill. Read the rest of this entry »

When it comes to stealing bases, the Central division leaders couldn’t be more different. The Pirates rank first in baseball with 44 steals in 53 attempts; the Twins rank last with six steals in 11. But for the past ten games, these two teams have been taking a similar approach. Since the end of April, both have been ramping up their efforts, stealing far more often than they did over the first few weeks of the season. To be fair, that means something completely different for either club: for Pittsburgh, it means stealing at a rate we haven’t seen in years; for Minnesota, it means simply stealing at all. In both cases, it warrants a closer look.

In 2022, the Twins ranked last in baseball with 38 steals and 55 stolen base attempts. Their team leaders in stolen bases, Byron Buxton and Nick Gordon, had just six steals apiece. The Rangers, who led the league in steals, ran more than three times as often as the Twins:

Part of the problem was the lineup Minnesota was working with. Of its top five players by plate appearances, the fastest runner was Carlos Correa, who had a sprint speed in the 44th percentile and hasn’t been a stolen base threat since his age-21 season. Luis Arraez, Gio Urshela, Jose Miranda, and Gary Sánchez were the only other Twins with more than 450 PA, and none of those guys is winning a footrace, to put it kindly.

Even the fastest players in Minnesota were hesitant to run, however. Buxton was only on pace to add another four or five steals had he remained healthy; a player with his skills could have easily stolen 25–30 bags, at least. Presumably, he was staying put out of an abundance of caution for his physical safety, yet if that were the only explanation, it’s odd he was running as often as he did. He stole enough bases to put himself in harm’s way, but he wasn’t running enough to maximize his value on the basepaths. Other Twins who stole less than you’d expect included Gordon, Jorge Polanco, and Max Kepler. All three had above-average sprint speeds and above-average OBPs, but they attempted significantly fewer steals than in 2021. In other words, speed wasn’t the only problem. By all appearances, the Twins were discouraging their players from taking extra bases. Read the rest of this entry »

If Matt Strahm wasn’t on your radar before this season, I can’t blame you. The left-hander put up increasingly worse results during his four years with the Padres, culminating in a 2021 season lost to injury. He bounced back the following year as a solid middle reliever for the Red Sox, but even so, he was hardly a free agent to watch this winter. He only made headlines because the two-year, $15 million deal he signed with the Phillies was more lucrative than anyone expected for him; an unnamed executive claimed that the contract “destroyed the market” for left-handed relievers.

A few years back, though, Strahm was a top-100 prospect and the most promising name in the Royals’ system. He earned his first feature here at FanGraphs in August 2016 in a piece that called him “a new relief weapon.” He was marvelous that season, posting a 1.23 ERA and 2.06 FIP across 22 innings for the reigning world champs. A year later, he earned another look from the FanGraphs staff, this time as the headlining return in the Trevor Cahill trade between the Royals and Padres. The summer after that, Strahm was once again the star of a FanGraphs story, this one about his work as an opener. Travis Sawchik looked at Strahm’s success and wondered if “Hader Lite” was an appropriate nickname. That’s high praise, indeed.

All this to say, Strahm isn’t just some guy, no matter how much his new nickname (Pastrami, i.e. “Pa-strahm-i”) makes him sound like the manager of an old-time Brooklyn deli or a kid from The Little Rascals. At the same time, he hasn’t been particularly relevant for several years, and as he entered his age-31 season, you might have thought the former top prospect was done making headlines.

Six games into his Phillies career, Strahm demands attention. He ranks 10th among National League pitchers (min. 20 IP) with a 2.31 ERA and among the top 10 in all the major ERA estimators: FIP, xFIP, xERA, and SIERA. The only other NL pitchers who can say the same are Spencer Strider, Zac Gallen, and Max Fried — arguably the early-season frontrunners for the National League Cy Young.

The Rays continue to play phenomenal baseball. While their 14-game home winning streak came to an end on Tuesday night, they have won six of their last seven and boast what is easily the best run differential in the sport. Their average margin of victory is 3.7 runs, which is more than the Tigers, Marlins, and Royals are scoring per game. As if all that weren’t enough, Tampa Bay is only getting stronger. Zach Eflin returned from a back injury on Sunday and twirled five innings of one-run ball. Tyler Glasnow threw his first simulated game on Monday, a critical step in his rehab process as he works to rejoin the rotation. Meanwhile, top prospect Taj Bradley is waiting in the wings after making a fantastic big league debut.

For all that good stuff, however, the Rays have also been dealt a significant blow. On April 13 against the Red Sox, Jeffrey Springs looked down at his elbow after throwing a pitch; it would turn out to be his last of the 2023 campaign. Coincidentally, the Rays would lose their first game of the year the following day. Springs landed on the injured list with a diagnosis of ulnar neuritis but was later revealed to have torn his UCL; he underwent Tommy John surgery earlier this week to repair the ligament, leaving the Rays to go the rest of the way without the player who could have been their biggest success story. That’s a bold claim to make about a man on the same team as Yandy Díaz and Randy Arozarena, but that’s just how well Springs was pitching. Read the rest of this entry »

On Thursday, the internet dealt with countless cases of “Is that really who I think it is?” as Twitter removed verification checkmarks for unpaid users. Yet when baseball fans did a double-take, it wasn’t because of a spam account that looked suspiciously like Jeff Passan or Ken Rosenthal. Instead, it was because of a shortstop who looked suspiciously like Mookie Betts.

Dodgers manager Dave Roberts teased fans earlier this week, revealing that Betts could play shortstop on Wednesday. Instead, it was Luke Williams who took to the field at game time. Fans got their hopes up for Betts the following day, but once again, it was Williams on the lineup card. Indeed, it wasn’t until the seventh inning of yesterday’s ballgame that Roberts finally made good on his word; he pinch-hit for Williams with Betts, and Betts would stay in the game at shortstop. Williams may have earned the nickname Captain America for his performance with the US Olympic baseball team, but Betts was the superhero – or should I say super-utility player – everyone wanted to see.
