Major League Baseball’s rules have been in a constant state of flux during the 2020s, with the implementation of the extra-innings runner (the so-called Manfred Man), the universal designated hitter, the three-batter minimum, the pitch clock, the disengagement rule, larger bases, and the infield shift ban accompanying additional changes to roster sizes and the injured list. Most — but not all — of these rule changes have been aimed at livening the game up, with more action and fewer dead spots, and have generally favored offenses rather than pitchers. This year’s Big New Rule is the Automated Ball-Strike Challenge System, which has shaken up batters’ and pitchers’ understanding of the strike zone. With the month of April now behind us, it’s worth checking in on this season’s numbers, in part to see what kind of impact the ABS is having.

For starters, scoring levels are up, both relative to last year as whole and to the opening month, by which I mean April plus the handful of games in March that preceded it (a convention I’ll maintain throughout this article). In a vacuum, that would rate as a bit of a surprise, since temperatures are generally cooler in the opening weeks than in the summer months, reducing the extent to which fly balls carry, and thus scoring levels. On the other hand, pitchers tend not to throw as hard as they do later in the season, which would favor hitters, as well. Yet through the end of April, teams are scoring more runs per game than in all but one of the past five seasons’ opening months:

I’ve included a bunch of numbers there to unpack, but first I’ll note that the timing of Opening Day influences the size of these samples. The 2021 season began on April 1, while the owners’ lockout delayed the start of the ’22 season until April 7. With the ensuing Collective Bargaining Agreement creating the need to shoehorn an additional round of playoffs into the schedule, Opening Day is now routinely a March thing, and it often begins with the baseball equivalent of an amuse-bouche. While all 30 teams kicked off play on March 30 in 2023, in ’24 a pair of games in Seoul on March 20–21 preceded the stateside Opening Day of March 28. The 2025 season began in similar fashion, with a pair of games in Tokyo on March 18–19 before everybody else got down to business on March 27. This year featured one game on March 25, with just about everybody else starting on March 26. Read the rest of this entry »

The moment may prove fleeting, but at this writing, the Braves have a claim as the best team in baseball. At the outset of this season, Atlanta looked as though it might be headed for disaster yet again due to injuries and absences, with another Jurickson Profar suspension and the loss of Spencer Strider providing a particular sense of déjà vu. Instead of stumbling out of the gate, however, and even with a far-from-complete roster, the 2026 Braves have dominated opponents on both sides of the ball. At 21-9, they own the majors’ best record — and it appears they’ll get Strider back soon, as well.

Nearly five weeks in, the Braves haven’t lost a series. They kicked things off at Truist Park by taking two out of three from both the Royals and A’s, then went on the road and split a four-game set with the Diamondbacks before taking two out of three from the Angels. Upon returning to Atlanta, they took two of three from both the Guardians and Marlins, and after that sandwiched a pair of series wins against the reeling Phillies — a three-game sweep in Philadelphia and then two out of three at home — around a three-out-of-four series win in Washington. That’s eight series wins and one tie to date; by comparison, the Dodgers and Yankees (both 20-10) have each dropped pair of three-game series and split a four-gamer.

To be fair, after last year’s 76-86 dud and the retirement of manager Brian Snitker (replaced by bench coach Walt Weiss), the Braves were still essentially projected as NL East co-favorites alongside the Mets, according to our Playoff Odds, with a forecast for 89.6 wins, a 30.6% chance of winning the division, and a 79.0% chance of making the playoffs. Still, few expected them to return to dominate in such fashion. Through 30 games, they’ve matched the second-best start in franchise history, a record shared by the division-winning 1969 and 2000 editions. The only time they’ve started better was in 1997, when they went 22-8 and finished 101-61. They’ve gone 16-6 against sub-.500 teams without even getting a shot at the struggling Mets, and 5-3 against teams .500 or better. Their current record isn’t a fluke, in that they’ve actually got slightly higher Pythagorean- and Base Runs-projected winning percentages (.722 and .695, respectively) than their actual mark; both of those rank second in the majors behind the Dodgers, while their +68 run differential is tops. The Braves have run up those numbers by scoring a major league-high 5.70 runs per game and allowing just 3.43 per game, tied with the Yankees for second in the majors and behind only the Dodgers.

Three weeks ago, things weren’t looking great for the Cubs. True, the season hadn’t hit the two-week mark at that point, but the NL Central favorites had started 4-6 and were running last in the division. Two members of their starting rotation, Matthew Boyd and Cade Horton, had just landed on the injured list, and right fielder Seiya Suzuki had yet to play after straining a ligament in his right knee during the World Baseball Classic. Soon, the injury bug would bite their bullpen, as well, but just as it did, the team reeled off a 10-game winning streak, the majors’ longest this season. While that ended on Saturday at the hands of the Dodgers, followed by another loss on Sunday, the Cubs do appear to be back on track. With a 17-11 record, they’re one game behind the Reds for the division lead.

Their streak began on April 14, a day after the Phillies pounded them 13-7 at Citizens Bank Park. To that point, the Cubs were 7-9, having won three-game series against the Angels and Rays but lost three-game series to the Nationals, Guardians, and Pirates. But Chicago turned the tables on the Phillies by dropping double-digit run totals on back-to-back days, winning 10-4 and 11-2, before returning home to kick off a sweep of the Mets with a 12-4 victory. The Cubs then capped that sweep two days later with Nico Hoerner’s 10th-inning walk-off sacrifice fly, then circled back to take four straight from the Phillies, including another 10th-inning walk-off, this time on a Dansby Swanson single on April 23. Their winning streak reached 10 games with a 6-4 victory over the Dodgers in Los Angeles on Friday. It was Chicago’s longest since 2016, when the club won 11 straight from July 31 to August 12.

It certainly didn’t hurt that the Cubs’ schedule coincided with both the Mets and Phillies playing particularly bad baseball. New York lost 12 in a row from April 8-21 and Philadelphia 10 in a row from April 14–24; both finished the weekend 9-19. The Cubs own the NL’s highest winning percentage against sub-.500 teams (.750, a 12-4 record), though they’re just 5-7 against those .500 or better after their two losses in Los Angeles this weekend.

Led by American League Cy Young runner-up Garrett Crochet, free agent signee Ranger Suarez, and trade acquisition Sonny Gray, the Red Sox were projected to have the majors’ top rotation in our preseason Positional Power Rankings. Four weeks in, the unit has been one of the majors’ worst, with Crochet getting pummeled and Gray underperforming before landing on the injured list earlier this week with a right hamstring strain. The bullpen has been shaky, the offense weak, and after losing the first two games of a three-game series against the Yankees at Fenway Park, the Red Sox now sit 9-15, last in the AL East.

Through 24 games, this is the Red Sox’s worst start since 2020, when they went 6-18 en route to a 24-36 record and a last-place finish. In terms of full-season futility, in 2019 the Red Sox — defending champions at the time — started 9-15 before rallying to finish at 84-78, third in the division but outside the playoff picture. After winning 89 games last season and making their first postseason appearance since 2021, this year was supposed to be different, but since Opening Day, the team’s seasonal win projection has fallen from 85 to 80.5, the fourth-largest drop in the majors ahead of only the Mets (-7.1), Phillies (-5.7) and Royals (-4.5). Only those three teams have larger drops in their Playoff Odds:

The driver of Boston’s success was supposed to be the rotation, headed by Crochet. After making his first All-Star team with the White Sox in 2024, he emerged as a true ace last year, leading the majors in both innings (205.1) and strikeouts (255) while ranking second in the AL in strikeout rate (31.3%), xERA (2.88), FIP (2.89), and WAR (5.8) — behind Cy Young winner Tarik Skubal in all of those categories — and third in ERA (2.59).

When the Dodgers signed Edwin Díaz to a three-year, $69 million deal last December, it marked the second straight winter that they paid top dollar for a free agent closer, after they’d inked Tanner Scott to a four-year, $72 million deal in January 2025. That they double-dipped in such fashion was both a particularly ostentatious display of their purchasing power and an acknowledgement that even the best relievers can be fickle and fragile. Scott scuffled throughout last season while also missing time due to multiple injuries, and ultimately spent October as a bystander as the Dodgers cobbled together a makeshift late-game bullpen and won their second consecutive championship. Now, after struggling with his velocity and command, Díaz has also gone down with an injury. On Monday, one day after failing to retire any of the four Rockies he faced, he was placed on the 15-day injured list due to loose bodies in his right elbow. He is set to undergo arthroscopic surgery on Wednesday to have them removed.

Even in small-sample season, the 32-year-old Díaz’s numbers tell enough of a story to suggest that something is amiss. He’s allowed seven runs in six innings for a 10.50 ERA, accompanied by a 4.96 FIP and a 4.39 xERA. His 15.2% differential between his 30.3% strikeout rate and 15.2% walk rate is just over half of his 29.8% differential last year. His four-seam fastball has averaged just 95.7 mph, down from last year’s average of 97.2 mph while with the Mets, for whom he posted a 1.63 ERA and a 2.28 FIP in 66 1/3 innings. His average arm angle has dropped, changing the movement profiles of both his four-seamer and slider:

Relative to last season, Díaz has lost over two and a half inches of horizontal run on his fastball and nearly an inch of cut on his slider, which itself is one mile per hour slower, as well. Neither pitch has fooled hitters to nearly the same degree as before, and his overall swinging strike rate has dropped from 17.3% in 2024 and 18.0% last year to 9.1% this season.

Jay Jaffe: Good afternoon, and welcome to another edition of my weekly chat. I’ve got a piece about Edwin Díaz’s impending elbow surgery in the pipeline, while yesterday I wrote about Yordan Alvarez’s hot start (https://blogs.fangraphs.com/amid-houstons-problems-yordan-alvarez-is-l…).

Jay Jaffe: Last Friday, I wrote about the Mets’ losing streak (https://blogs.fangraphs.com/no-offense-the-new-look-mets-are-in-quite-…), which has now reached 11 games. It’s brutal.

Jay Jaffe: Thanks to everyone who had kind words about my tribute to Davey Lopes (https://blogs.fangraphs.com/davey-lopes-1945-2026-speedster-student-an…), my first favorite player. And now, on with the show…

12:05

Jay Jaffe: Hah, that is brutal. I focused my piece on the offense’s shortcomings, knowing that there would probably be room for a follow-up on their pitching or some other aspect of their struggles at some point, but I did expect them to at least win a game here or there along the way.

These are not good times for the Astros. The team has stumbled to an 8-15 start, and while slow starts themselves are nothing new for Houston, this Astros’ roster has been particularly depleted by injuries. Including All-Stars Hunter Brown, Josh Hader, and Jeremy Peña, they currently have a major league-high 14 players on the injured list. In the grand scheme, one of the few thing going right for the club is the return of Yordan Alvarez, who’s back to being healthy and unstoppable. Limited to just 48 games by injures last year, the 28-year-old slugger has not only played every game, but has hit a major league-high 10 homers.

During Sunday’s game against the Cardinals at Daikin Park, the Astros trailed 4-1 with two outs and nobody on when Alvarez stepped in against lefty JoJo Romero in the eighth inning. In running the count to 2-2, he fouled off three pitches, including a sweeper that was well off the plate. Romero then threw him a changeup that sank below the bottom edge of the zone, and Alvarez went down and got it, hitting a towering solo homer to right field:

The Astros then added two more runs in the inning as Jose Altuve and Isaac Paredes sandwiched singles around a Christian Walker walk and a wild pitch from incoming reliever Riley O’Brien. That tied the game, which went to extra innings, where the Astros couldn’t do enough to counter the three runs the Cardinals scored against reliever Bryan King; they lost 7-5.

The Mets’ 2026 season began with such promise. With a remade roster after last year’s disappointing 83-79 finish — new looks in the infield and outfield, a new Opening Day starter to lead their staff, and infusions of youth both in the lineup and in the rotation — they kicked things off by beating up reigning NL Cy Young winner Paul Skenes and won three out of their first four games. Though April 7, they were 7-4, including a pair of walk-off wins. They haven’t won since, and already owner Steve Cohen is pleading with fans to stay the course.

First, the Mets dropped the final five games of their second homestand against the Diamondbacks and Athletics, getting shut out twice and scoring more than two runs just once; meanwhile, they gave up seven or more runs three times. Then they flew to Los Angeles to face the two-time defending champion Dodgers, and while they did get a seven-inning, one-run gem from rookie Nolan McLean opposite Yoshinobu Yamamoto on Tuesday night, they lost all three games by a combined score of (gulp) 14-3.

At 7-12, the Mets are tied with the Giants and Rockies for the National League’s worst record. They’re last in the NL East, five games behind the Braves, who have bolted from the gate by winning 12 of 19 despite injuries to a full rotation’s worth of starters, including Spencer Strider and Spencer Schwellenbach, as well as catcher Sean Murphy and shortstop Ha-Seong Kim. If there’s good news, it’s that the rest of the division has started sluggishly as well, with every team besides the Braves below .500. The Mets are only two games out of second place, not that that adds wins to their ledger. Read the rest of this entry »

Konnor Griffin isn’t the only rookie infielder to land a nine-figure extension within his first few weeks in the majors. On Wednesday, the Tigers reached an agreement with Kevin McGonigle — who made the jump from Double-A into Detroit’s Opening Day lineup and has been the team’s top hitter thus far — on an eight-year, $150 million extension for the 2027–34 seasons. The contract slightly surpasses the value of Griffin’s deal, making it the largest guarantee to a player with fewer than 100 days of major league service time, even before its other bells and whistles are considered.

According to MLB.com, McGonigle will receive a signing bonus of $14 million, $8 million of which is payable within 30 days and the rest in 2028. He’ll then earn $1 million next season, $7 million in 2028 (when he would have qualified for Super-Two status), $16 million in ’29, $21 million in ’30, $22 million in ’31, and then $23 million annually from ’32–34, which would have been his first three years of free-agent eligibility. Escalator clauses can increase the values of the deal by an additional $10 million, with higher salaries for those last three seasons of $25 million (2032), $26 million (2033), and $28 million (2034).

Those escalators are based on MVP voting and other honors, and can be triggered starting this season, per ESPN. McGonigle could get boosts of $2 million for winning an MVP award, $1 million for finishing second through fifth in MVP voting, and $500,000 for finishing sixth through 10th; he’ll also get $500,000 for making the All-MLB first or second team, $250,000 for making an All-Star team, and $250,000 for winning a Silver Slugger award. His contract has no options or opt-out clauses, but additionally includes a $5 million assignment bonus for every time he’s traded to another organization under the life of the contract.

Davey Lopes was my first favorite ballplayer. In retrospect, I’m not sure how my eight-year-old self settled upon Lopes in a star-laden lineup featuring power hitters Dusty Baker, Ron Cey, Steve Garvey, and Reggie Smith, who the year before (1977) had become the first quartet of teammates to homer 30 times apiece in a season. I have a much better grasp of how Bill James helped my teenage self appreciate Lopes for his combination of high on-base and stolen base rates with mid-range power, but James wasn’t communicating those ideas via mass-market paperbacks circa 1978. Perhaps it was Lopes’ position atop the lineup I memorized while learning to decode box scores (my theory) or the Topps baseball card set that began my collection. Maybe it was simply his instantly recognizable, bushy mustache (my friends’ theory), but one way or another, even before later heroes such as Fernando Valenzuela and Jim Bouton, Lopes was my guy.

The news that Lopes passed away on April 8 at age 80 due to Alzheimer’s and Parkinson’s diseases — a brutal double bill — reached me while I was traveling in Austria with my own 84-year-old parents and additional family as we tracked down the Vienna addresses of my long-deceased paternal grandparents. I had no shortage of thoughts regarding mortality, and yet the hits kept coming. Lopes wasn’t even the most recent former All-Star-second-baseman-turned-manager to pass away, as Phil Garner, his National League rival and then predecessor in managing the Brewers, died of pancreatic cancer on April 11. So it goes.

Though he didn’t debut until well past his 27th birthday, Lopes spent 16 seasons in the majors (1972-87), the first 10 with the Dodgers, whom he helped to four pennants and a championship while making four All-Star teams, winning a Gold Glove, and becoming team captain. From 1973–81, he manned the keystone in the longest running infield in major league history, along with Garvey at first base, Cey at third, and Bill Russell at shortstop — a unit that formed the foundation of those pennant-winning teams under managers Walter Alston and Tommy Lasorda. “He was the catalyst of the engine. It was 700 horsepower with the four of us, and the equation was his ability to get on base,” Garvey told CBS LA in the wake of Lopes’ death. Read the rest of this entry »
