The Pirates are off to a surprisingly hot 13–7 start, tied for the fifth-best record in the majors, and they have a burgeoning offense to thank. At the close of play on Thursday, after scoring 37 runs over a four-game stretch, they rank second in the National League with 103 runs scored, are tied for fourth in the majors with 27 home runs, and are third with a .446 team slugging percentage and eighth with a .339 wOBA. They’ve managed to limit strikeouts — they’re seventh among major league teams with a 20.6% strikeout rate – and have improved their walk rate by two percentage points since last year. Pirates pitching has handled their side of business well enough — their 12th-ranked 4.03 ERA represents a significant improvement from 2022 but looks a little cleaner than their 17th-ranked 4.30 FIP and 22nd-ranked 4.55 xFIP — but the real bright light has been that offense.
We’re already getting to the appropriate time in this piece to repeat FanGraphs’ April refrain: it’s early. But when looking for answers this early in the season, I like to follow a general rule of thumb: the more granular the data, the better. As Russell Carleton wrote in this 2011 piece, “The way to increase reliability of a measure is to have more observations in the data set.” This early in the season, we can often learn more reliably from statistics that are based on every pitch a hitter sees or every swing he takes — something like swing rate or contact rate — than metrics with at-bats or plate appearances in the denominator. This makes plate discipline and pitch selection a good area to explore looking for answers in April.
In the case of the Pirates, improved pitch selection has been a great triumph so far this year — and it’s not that they’re necessarily being more patient, but more that they’re making better decisions. The team is swinging at 45.5% of offerings this year, down just a tenth of a point from last year, but far more of those swings are targeting pitches in the zone. Pittsburgh ranks second in the majors with a 27.9% chase percentage, an improvement from 31.7% last year. After finishing dead last in 2022 in zone swing percentage at 65.3%, the Pirates are all the way up to sixth this season with a 69.3% rate. The improvements have been nearly universal, but even as their depth has been tested with injuries to Oneil Cruz and Ji-Man Choi, a few picky Pirates are leading the way.

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.

Pablo López is off to a good start in his first season with the Twins. Acquired by Minnesota from Miami as the centerpiece of an offseason deal that sent defending American League batting champion Luis Arraez to the Marlins, the 27-year-old right-hander has a 1.73 ERA and a 2.70 FIP over 26 innings. Moreover, he’s fanned 33 while surrendering just 15 hits and issuing six walks.
Trading in his cutter for a sweeper has played a part in that success. López has thrown his new offering 82 times — all against same-sided hitters — over four starts, and only twice has the result been a base hit. His Whiff% on the pitch is an eye-opening 50%.
The repertoire tweak was made at the behest of López’s new team, but the idea of a sweeper preceded his arrival.
“I first got the concept at Driveline in the offseason,” explained López, who logged a 3.75 ERA in a career-high 180 innings last year with Miami. “But I was only there for a short visit, so I couldn’t really capitalize on the concept of it. Then, in spring training, it was brought up again. From there we sat down and worked on it.” Read the rest of this entry »
There are a lot of reasons why the Astros are off to a cold start in 2023 and, as of Thursday morning, are looking up at the Angels and Rangers in the AL West standings. While their Pythagorean record suggests they’ve actually played better than their record, their April offense has been an extremely unbalanced one. To a large extent, the AL’s fifth-place team in runs scored has been driven primarily by Yordan Alvarez and Kyle Tucker.
The Astros currently have three positions with an OPS under .600 for the season: catcher, first base, and designated hitter. Catcher as an offense sink was always expected; nobody had a secret belief that Martín Maldonado had offensive performance as part of his skill set. Designated hitter should improve once it has a smaller dose of David Hensley and Corey Julks at the position. That leaves first base, the home of José Abreu, the longtime White Sox slugger who was Houston’s biggest signing this winter. He has struggled in the first eighth of the season, hitting .266, but with so little secondary contribution that his OPS stands at a miserable .605. Given his age, three-year deal, and the necessity to get at least some offensive contribution from first base, how worried should the Astros be about him?
The general belief, at least among Astros fans, is that Abreu has historically been a slow starter, and that any issue will take care of itself, but I think that’s too easy a “solution” to his early-season struggles. First off, the supposition that he has historically been a worse hitter in April is factually 100% accurate. Among players in the wild-card era, he has one of the largest splits between April and rest-of-season OPS (OPS is certainly good enough for an examination such as this). Since the start of the 1995 season, there are 300 players who have accumulated at least 750 plate appearances in April; Abreu’s career split — 90 points of OPS — is large enough to make the top 20 and, unless I’m miscounting, enough to rank him third among active players:
Offense is generally lowest in April, so some kind of shortfall is not unexpected. The 300 players in this class, as a group, had a .794 OPS in April and an .806 OPS the rest of the year. With a quarter of a million April plate appearances between them and a total of nearly two million plate appearances, a 12-point OPS is a significant one, and Abreu’s history dwarfs this one.
So, he’s a bad player in April, and everything will just work outself out? Not so fast. Read the rest of this entry »
Hunter Greene left his most recent start after taking a comebacker off his right shin, but the 23-year-old righty appears set to stick around Cincinnati for awhile. Per ESPN’s Jeff Passan, the fireballer agreed to a six-year, $53 million extension (2023-28) with a seventh-year club option. Remarkably, amid the Reds’ teardown, this deal makes him the roster’s first player with a guaranteed salary for next season.
Via MLB Trade Rumors, this is the second-largest extension for a pitcher with between one and two years of service time, after Spencer Strider’s six-year, $75 million deal with the Braves. Strider sold high, so to speak, signing that contract coming off a 202-strikeout, 1.83-FIP season in which he was runner-up to teammate Michael Harris II in the NL Rookie of the Year voting. Greene, who’s less of a finished product, didn’t have quite that kind of platform.
Chosen with the second pick of the 2017 draft out of Notre Dame High School in Sherman Oaks, California — at a point when he was still a two-way player — Greene quickly shifted his focus to pitching and found early success in the minors. He earned a spot in the 2018 Futures Game, but not long afterwards sprained his UCL and lost a season and a half to Tommy John surgery. When he debuted in the majors on April 10, 2022, he had just 186 minor league innings under his belt, which is to say that he was still rather raw. Particularly considering he was on a team that lost 100 games, and that he was hit hard early in the year, he acquitted himself well, posting a 4.44 ERA and 4.37 FIP in 125.2 innings.

I might as well throw out all the usual caveats up front. It’s April. Sample sizes are still miniscule. The ball might be different. The rules are definitely different. I could go on. All of that is true, but it doesn’t change this essential fact: José Alvarado is on an otherworldly tear right now, putting up best-reliever-in-baseball numbers for a Phillies team that desperately needs the help.
Let’s start with the numbers, because they’re overwhelming. Alvarado has faced 29 batters so far this year. He’s struck out 18 of them. That’s a 62.1% strikeout rate, or as I like to call it, a made up strikeout rate. You can’t conceive of a 62.1% strikeout rate. It’s nonsense math. Nearly two-thirds of the batters who have come to the plate against Alvarado this year have walked back to the dugout with nothing to show for it but a sad face.
As you can no doubt imagine, you need to miss a lot of bats to put up strikeout numbers like that. Alvarado has posted a 20.8% swinging strike rate so far this season, seventh-best among relievers even in the small sample of April, when outliers rule. That’s a career high for him, obviously, but not by as much as you’d think: He posted a delectable 16.7% mark for all of 2022. Read the rest of this entry »
Well, shoot. After grounding out to shortstop in the second inning of Wednesday night’s game against the Nationals, Jorge Mateo was removed due to hip discomfort. The Baltimore shortstop is officially day-to-day, and Rotowire reports that he seems to have avoided a serious injury, but the timing still stinks. Mateo is on the hottest streak of his short career: After 16 games, he has a 192 wRC+ and 1.1 WAR, tying him for third and fourth in baseball, respectively. Naturally, he wasn’t going to be able to keep this up for a whole season; he has a .378 BABIP, and his wOBA exceeds his xwOBA by 59 points. It’s April 20, and the regression monster is laying in wait right for him right now.
But that’s part of what makes his hot start so fun. This is Jorge Mateo! The light-hitting, glove-first speedster. He was a fun player when he was just stealing bases, making jump throws from the hole, and trying to beat out infield hits. All of a sudden he’s got a .638 slugging percentage. In the last 16 games, he’s raised his career wRC+ by 9%. Obviously, I’m going to examine whether any of this looks sustainable, but first let’s take a moment to enjoy what we’re seeing while spring is in the world. Read the rest of this entry »
What an absolute rocket. With a 118.2 mph exit velocity, Jake Burger’s three-run dinger was the second-hardest hit ball of the season so far. Harder than anything that’s come off the bat of Aaron Judge or Yordan Alvarez in 2023. Hard enough that this ball went 417 feet with just a 21 degree launch angle. That’s not the launch angle of your standard-issue ballistic arc moon shot. Anyone who watched La Fleche Wallonne on Wednesday can tell you it’s possible to ride a bicycle up a 21-degree incline.
But that’s just the kind of week Burger’s been having. Since being recalled to the majors on April 6, Burger has eight hits. Seven of them have gone for extra bases, and five of those have been home runs. Of those five home runs, four have come in the past six days. Back in the day, the only way to display that much power in Chicago was to tilt a presidential election for John F. Kennedy.
It was not always ordained to be so. With a couple weeks to go in spring training, I asked Burger what he thought of his prospects for making the Opening Day roster. He came into camp facing entrenched starters at basically every position he’s capable of playing; if he was competing for anything, it was a spot on the bench. But with Luis Robert Jr., Eloy Jiménez, and Yoán Moncada at the WBC, he got all the playing time he could ask for in camp.
“I’ve been in basically every game,” he said. “I’m fortunate to be in that position and to be able to compete for a job. Take it day by day and just be myself. The rest will take care of itself.”
It’s the kind of answer that would make Crash Davis stand up and applaud, but Burger gave it with conspicuous confidence for someone whose major league career has been anything but a sure thing.
In 2017, Burger was the no. 11 overall pick out of Missouri State, where he played with future big leaguers Matt Hall and Dylan Coleman, fellow first-round pick Jon Harris, and a pitcher named Trey Turner. (Not to be confused with Phillies shortstop Trea Turner, former Virginia Tech wide receiver Tré Turner, or five-time Pro Bowl offensive guard Trai Turner.) Burger was one of the best mid-major hitters in the country over three years in Springfield, boasting back-to-back seasons of hitting at least .300/.400/.600 with at least 20 home runs as a sophomore and junior. He figured to rise through the minors quickly.
But four days into Cactus League play in his second pro season, Burger tore his Achilles tendon. Ten weeks later he tore it again. He missed all of 2019 with a heel injury, then all of 2020 due to the pandemic canceling minor league play. Concerns about Burger’s long-term suitability for third base were not alleviated when his ankles and feet betrayed him, and few young hitters can survive going three seasons without playing a competitive game.
In the meantime, the White Sox were stocking up on competitors for playing time. Moncada moved from second base to third base in 2019. Jiménez and Robert established themselves as big league regulars in the outfield, and Chicago spent top 10 picks on Andrew Vaughn and Zack Collins, a college catcher who profiled as a future first baseman or DH. When Burger did finally make it to the majors, he got hurt again, this time breaking his wrist in July.
Burger missed out on the Opening Day roster, but he didn’t have to wait long in the minors. Within a week, Jiménez tweaked a hamstring and went on the IL, and when he was ready to return, Moncada went on the IL himself with a back injury. Now, Burger is not only on the roster, he’s Chicago’s starting third baseman.
But even after the opportunity to play opened up, Burger wasn’t going to make much headway striking out 30% of the time. He was good at the plate when healthy — a 113 wRC+ in 183 PA last season — but not enough to force a more established player out of the lineup.
“Cutting down the strikeouts and working on bat-to-ball skills was a big factor in this offseason,” he said. “If I can consistently make contact, the ball is going to jump.”
In addition to making some mechanical changes, Burger also tried to refine his pitch selection. He said he wanted to lay off low pitches — even strikes — that he was more likely to ground out than hit hard in the air. Burger can hit the ball hard, as his home run off Falter would indicate, but it’s easiest for him when the pitch is either at belt-level or up in the zone and away. Pitches low in the zone have traditionally caused him problems:
Despite this, last season he swung at about two-thirds of pitches in the lowest third of the strike zone. That low-middle sector, with a 71% swing rate, netted Burger a contact rate of 79% but a slugging percentage of just .222 on the balls he did manage to put in play. He said his goal this past offseason was to work on “creating a floor in the strike zone.”
So how did he do that? Cool gadgets.
“I use WIN virtual reality, which is pretty cool,” he said. That system involves a bat sensor and a VR headset, which allows him to simulate at-bats off any pitcher in baseball. “Also, my training facility in Nashville has been huge, using an iPitch machine, and you can put in any pitch in the major leagues.”
It’s not the real thing, but it’s close enough for someone who’s finally catching up after three seasons on the shelf. It’s a small sample, but through Wednesday’s games, it appears that Burger’s time on the holodeck has paid off:
If this is a genuine reinvention for Burger and not just small sample noise, it comes at an interesting time. It’s been more than half a decade since the White Sox blew up the talented and cost-controlled core of Chris Sale, Adam Eaton, and José Quintana. And after back-to-back playoff appearances in 2020 and 2021 generated a grand total of zero advancements to the second round, the Sox look like they’re going backward.
Until now, it looked like Burger was just one in a line of homegrown players who failed to live up to (admittedly astronomical) expectations. And he might still be that. We’ll see. But that core is now in what should be its prime — including Burger, who turned 27 two weeks ago — and there are still open questions about Vaughn’s power and Jiménez’s ability to stay on the field, among other shortcomings across the roster. Soon, it might be time to tear it all down again, whether Burger keeps homering four times a week or not.
Clayton Kershaw didn’t need his 200th career win to burnish his Hall of Fame credentials, but on Tuesday night at Dodger Stadium, in his first start with the milestone within reach, he secured it in brilliant fashion. In an outing bookended by his pitching out of jams, Kershaw tossed seven scoreless innings against the Mets, a team he has utterly dominated throughout his career.
In securing the milestone, Kershaw joined Justin Verlander (244 wins), Zack Greinke (223), and Max Scherzer (203) among active pitchers, and Hall of Famers Don Sutton and Don Drysdale as those who won at least their first 200 games as Dodgers. He became the 121st pitcher in major league history to reach the plateau, and just the 13th to do so entirely with one team:
Before we go further, it’s time for the usual caveat about pitcher wins: Regular readers know that I generally avoid dwelling upon the stat, because in this increasingly specialized era, they owe as much to adequate offensive, defensive, and bullpen support as they do to a pitcher’s own performance. While one doesn’t need to know how many wins a pitcher amassed in a season or a career to appreciate his true value — and single-season totals in particular can be wildly misleading — those totals do affect the popular perceptions of their careers and still carry a certain cachet among players.

Tucker Davidson is looking to establish himself as a Los Angeles Angel. Acquired by the Anaheim-based AL club at last year’s trade deadline in the deal that sent Raisel Iglesias to Atlanta, Davidson is doing so with an approach heavily influenced by analytics. An admitted pitching nerd, the 27-year-old left-hander is well-versed in the metrics, and he’s using them to improve his craft.
He’s off to a solid start this season. Currently pitching out of the bullpen — the bulk of his professional experience has been as a starter — Davidson has a 2.53 ERA and a 2.48 FIP over four appearances comprising 10-and-two-thirds innings. His ledger includes both a win and a save.
Davidson sat down to talk pitching when the Angels visited Fenway Park this past weekend.
———
David Laurila: You’re a pitching nerd. How did that come about?
Tucker Davidson: “I kind of fell into it — how the ball moves, and the whole analytical part — around 2015-2016 when I was in college and first getting drafted. I was interested in why my fastball didn’t spin a bunch, but I could still throw four-seams and get swings and misses up in the zone. I wondered why I couldn’t make a two-seam sink much. Why is my slider good? It was basically a ‘Why is that?’ Read the rest of this entry »
