In a race for a playoff spot, every edge matters. Yet all too often, for reasons that extend beyond a player’s statistics, managers and general managers fail to make the moves that could improve their teams, allowing meager production to fester at the risk of smothering a club’s postseason hopes. In Baseball Prospectus’ 2007 book, It Ain’t Over ‘Til It’s Over, I compiled a historical All-Star squad of ignominy, identifying players at each position whose performances had dragged their teams down in tight races: the Replacement-Level Killers. I’ve revisited the concept numerous times at multiple outlets and have adapted it at FanGraphs in an expanded format since 2018.

When it comes to defining replacement-level play, we needn’t hew too closely to exactitude. Any team that’s gotten less than 0.6 WAR from a position to this point — prorating to 1.0 over a full season — is generally in the ballpark, though my final lists also incorporate our Depth Charts rest-of-season projections, which may nose them over the line. Sometimes, acceptable or even above-average defense (which may depend upon which metric one uses) coupled with total ineptitude on offense is enough to flag a team. Sometimes a club may be well ahead of replacement level but has lost a key contributor to injury; sometimes the reverse is true, but the team hasn’t yet climbed above that first-cut threshold. As with Supreme Court Justice Potter Stewart’s definition of hardcore pornography, I know replacement level when I see it. Read the rest of this entry »

It has not been a good season for Trea Turner. The two-time batting champion is in the midst of a career-worst season at the plate, hitting for a 79 wRC+ (.239/.287/.368) even after homering in three straight games, including a three-run shot off Pirates ace Paul Skenes on Wednesday night. What’s more, after breaking a streak of three straight below-average seasons at shortstop according to both Defensive Runs Saved and Fielding Run Value last year, he’s not only back in the red, but is tied for last at the position with -8 DRS, while being tied for fifth-worst with -5 FRV. All of which once again marks Turner as a fairly typical Phillies player.

Indeed, through ups and downs that have included four postseason appearances, one trip to the World Series, and two in-season managerial firings, one constant of the Dave Dombrowski era of Phillies baseball has been lousy defense. Since the start of the 2021 season, the team is 100 runs below average according to FRV (the majors’ seventh-lowest mark) and 127 below average according to DRS (fifth-lowest). It hasn’t stopped the Phillies from being competitive — or highly entertaining — though it may have cost them seeding here and there, to say nothing of the way last year’s Division Series against the Dodgers ended. But given the choice between good hitters with questionable gloves and slick fielders with subpar bats, the team has generally gone for the offensive boost and lived or died with the consequences.

Thus it was hardly a surprise that the Phillies ranked second-to-last in my recent aggregation of team defensive metrics, even with right fielder Nick Castellanos — who contributed -41 DRS and -45 FRV from 2022–25 before being released in February — no longer on the team, and Kyle Schwarber more or less a full-time designated hitter. The Phillies’ .672 Defensive Efficiency, the rate at which a team turns batted balls into outs, is lower than all but the Rockies (.669), while their -29 DRS is lower than all but the Twins’ -32.

While he’s never been a true liability on the infield, Max Muncy has generally been a player whose defensive contributions took a back seat to his offense. The Dodgers have long counted on Muncy’s combination of power and plate discipline to outweigh his shortcomings in the field while bouncing him from first base to second to third depending on their roster’s current needs. That handling has paid off handsomely, as he’s been a vital contributor to four pennant winners and three World Series champions since being plucked off the scrap heap in April 2017. This year, however, Muncy has really flashed the leather at third base, showing the best range of his career. He leads all third basemen in Statcast’s Fielding Run Value, while tying for second in Defensive Runs Saved.

According to Statcast, Muncy was 11 runs below average at third base in 3,817 innings from 2018–25, roughly the equivalent of four runs below average per full season of play; he was four below average by that measure in just 801.1 innings last year. This year, he’s already six runs above average in 621 innings. According to Statcast’s Outs Above Average, he’s gone from being the majors’ worst qualifier on plays coming in (-9) to tying for second-best (4). DRS has generally been more charitable in its assessment of his defense; he was 16 runs above average at third from 2018–25, and is eight above average this season.

Muncy is just one of several Dodgers whose defensive play has helped his team top the rankings in my annual midseason defensive breakdown, with shortstop Mookie Betts, center fielder Andy Pages, second baseman Alex Freeland, and catcher Will Smith also making major contributions to that placement. I’ll explain the methodology below, but first, a bit more about the 35-year-old slugger, who on Monday night hit a towering solo homer in the first Dodgers-Athletics matchup to feature both Max Muncys, who share the same birthday (August 25) and drafting team (Oakland).

Across two decades that have produced just three pennant winners and one champion between New York’s two teams, the city’s sports media industrial complex has spent a fair bit of time calling for one manager’s head or another, or at least stoking that sentiment among fans. Still, it rated as a bit of a surprise on Friday when the Mets announced they had fired manager Carlos Mendoza — er, announced “the departure of” Mendoza, as if he were a flight leaving LaGuardia Airport — and named former Padres manager Andy Green, who’d been the Mets’ senior vice president of player development, to serve as interim manager for the remainder of the season. It was the first time that either the Mets or Yankees had changed skippers during a season since 2008, when the Mets canned Willie Randolph during a California road trip. While the team’s play this season, and indeed for over a year, made the case for a switch, Mendoza didn’t assemble this expensive band of underperformers. But like so many managers before him, he took the fall for someone else’s flawed blueprint.

The Mets were 34-47 when Mendoza was axed, exactly halfway through this season, and halfway through the five-year contract of president of baseball operations David Stearns, who hired Mendoza in November 2023, five weeks after leaving the Brewers to join the organization himself. At the time of the firing, the Mets were last in the NL East and had the league’s third-worst record, with just a two-game margin separating them from the major league-worst Rockies. They had lost six games in a row — their third losing streak of at least five games this season — while being outscored 54-22. In the nightcap of a doubleheader against the Cubs on Wednesday, the Mets’ infield combined to make six errors, with a player at each position making at least one in the same game for the first time since 1962. Amid that debacle, fans chanted the name of bygone slugger Pete Alonso, whose departure via free agency last December has come to symbolize a roster overhaul that went too far.

“Embarrassing,” Mendoza said after the six-error game and the doubleheader sweep. “Overall, the whole day. Two losses, but the way we played overall. That last game was unacceptable. Everybody’s pissed. Everybody’s frustrated.” Read the rest of this entry »

Through their ups and downs this season — a pair of 10-game winning streaks here, a 10-game losing streak there — the one constant for the Cubs has been injuries to their starting pitchers. On that front, this week brought a flurry of bad news. Not only did both Edward Cabrera and Ben Brown land on the injured list on Wednesday, bringing their current total of sidelined starters to six, but president of baseball operations Jed Hoyer announced that Justin Steele, who suffered a setback in late April while rehabbing from his second Tommy John surgery, isn’t likely to rejoin the rotation this season. In need of warm bodies to provide some innings, the team swung a trade with the Mets to acquire lefty David Peterson, a 2025 All-Star who has been getting lit up this year, but if the Cubs aspire to maintain their hold on a playoff spot, they’ll need significantly more help ahead of the August 3 trade deadline.

At this writing, seven of the 11 pitchers who have made at least one start for the team this season — including openers — have landed on the IL at least once, and that count doesn’t even include Steele. With Wednesday’s moves, five of the six pitchers forecast to throw the most innings for the team in our preseason Positional Power Rankings were out hurt, though Thursday’s scheduled activation of Opening Day starter Matthew Boyd from his second IL stint reduces that count. The Cubs rotation ranked 20th in projected WAR in our PPR, with a projected 4.03 ERA and a 4.15 FIP, but even that level of performance has been unattainable. Currently, Chicago is 26th in starting pitcher WAR (2.9), with a combined 4.64 ERA and a 4.79 FIP, and while the team’s use of the occasional opener fuzzes up those stats a bit, the bullpen (including bulk pitchers) has netted -0.3 WAR, with a 3.82 ERA and a 4.62 FIP. Don’t even ask about ready help from the minors, as the organization’s top upper-level pitching prospects — Jaxon Wiggins, Brody McCullough, Brandon Birdsell, Connor Noland — either are currently hurt or have been ineffective. It’s a bleak situation everywhere you look, at least at the moment. Read the rest of this entry »

Kyle Tucker’s tenure with the Dodgers hasn’t gone as well as anyone hoped so far, and on Monday night at Target Field, things took a turn for the worse. After walking during his first plate appearance, he yielded to a pinch-runner upon reaching second base due to back spasms. While he hasn’t yet landed on the injured list, the Dodgers have set a timetable that allows for “a mental reset” — to use manager Dave Roberts’ term — as Tucker tries to end a prolonged slump.

Tucker apparently began experiencing back spasms when the Dodgers took the field in the bottom of the first inning, though he didn’t have any balls hit in his direction. When he batted with one out in the top of the second, he fouled off Zebby Matthews’ first pitch — a four-seamer just off the plate — then looked at four straight balls, three of them in similar locations to that initial offering. Tommy Edman followed with a single, at which point Roberts replaced Tucker with pinch-runner Alex Call, who took over in right field.

“Back just like lit up and [I] went out there just tried to hope that it would calm down or go away or something, I’d just keep flying through it,” said Tucker afterwards, adding that “finishing the swing hurt.”

Roberts first noticed Tucker’s discomfort when he was batting. “I saw him take his at-bat — a little bit of wincing and kind of when he was jogging to first base,” the manager said. “And then once he got to second base, I think it was just more not seeing him move the right way, and I didn’t want to put him in any more jeopardy.” Read the rest of this entry »

Fireworks season came early to Citizens Bank Park, where on Saturday evening the Phillies collected 17 hits — 10 for extra bases, including four home runs — in a 15-3 win over the Mets. Kyle Schwarber launched three of those homers, with two traveling more than 450 feet in the third inning, and by the time the fifth inning ended, Bryce Harper had hit for the cycle for the first time in his major league career. At the wrong end of that onslaught was Freddy Peralta, who was tagged for 10 runs in 2 2/3 innings. It was the worst start of his nine-year career, as well as a reminder of just how poorly the team’s offseason acquisitions have panned out.

Saturday’s start began inauspiciously enough, with Peralta allowing a two-out solo shot to Harper in the first inning. After falling behind 2-0, he threw a 93.9-mph four-seamer inside, but Harper was nonetheless able to extend his arms and lift a 37-degree blast. In the second inning, Peralta surrendered two more runs via the combination of an Alec Bohm single, a one-out J.T. Realmuto double, and a two-out Justin Crawford double.

At that point, the Mets were down 3-0, not a good start but hardly catastrophic, but Peralta began the third inning by serving up a 456-foot solo homer to Schwarber on a changeup at the bottom of the zone, and from there the floodgates opened. Harper doubled, Brandon Marsh singled and took second on a Marcus Semien throwing error, and after the first out, Bryson Stott and Realmuto hit back-to-back doubles. A strikeout, a Crawford walk, and a Trea Turner single later, and the Mets were down 7-0. Peralta was done for the evening, but the official scorer wasn’t quite done with him. Crawford and Turner scored when reliever Cionel Pérez left a middle-middle sinker for Schwarber to demolish, a 457-footer for his second home run of the inning, putting the Mets into an 11-0 hole.

Jay Jaffe: I have a piece on Freddy Peralta that should go live during this chat.

Jay Jaffe: That’s an interesting one to ponder, but I don’t think it makes great sense for the Mariners. Gilbert is a very good pitcher with one more year of club control, and the Mariners do seem to have rotation depth, but the margin between him and Skubal just isn’t big enough — to me at least — to give that up. I can certainly understand the impulse to go for it, though.

Jackson Chourio got a late start to his season. A fractured metacarpal in his left hand, suffered during the run-up to the World Baseball Classic but not definitively diagnosed until three weeks later, knocked him onto the injured list just hours before the Brewers’ Opening Day game, and he didn’t make his season debut until May 4. Since then, the 22-year-old outfielder has not only been one of the majors’ top hitters, he’s shown notable improvements in a few key areas while helping to propel the Brewers into first place in the NL Central. He’s becoming the star the Brewers hoped he would when they signed him to an eight-year, $82 million extension in December 2023, before he’d even debuted in the majors.

On Wednesday night against the Guardians, Chourio hit his 10th home run of the season, turning a high cutter from Gavin Williams into a two-run opposite-field shot that helped the Brewers to a 9-4 win:

Monday marked the one-year anniversary of the blockbuster trade that sent Rafael Devers from the Red Sox to the Giants in exchange for a four-player package. Neither team marked the occasion by throwing a party; mercifully, both were idle, and so didn’t sink further below .500. The deal hasn’t worked out well for either side, though it’s the Giants with an expensive and apparently declining slugger on the books. While Devers was fairly productive after being dealt last season, so far in 2026, the 29-year-old first baseman has surrounded one very good month (May) with a pair of miserable slumps that are just part of the reason the Giants are buried in the NL West standings.

We’ve told and re-told the story of the drama in Boston that led up to the Devers trade, but the streamlined version is that the signing of third baseman Alex Bregman bumped Devers off his natural position. After that, a lack of communication between the front office and the slugger — whose defense at the hot corner had eroded — exacerbated the team’s attempts to slot him first at designated hitter and then, after Triston Casas was injured, at first base, a position he had never played before and was reluctant to begin learning in-season. On June 15, 2025, the Red Sox sent Devers to the Giants for lefty Kyle Harrison, righties Jose Bello and Jordan Hicks, and outfielder James Tibbs III, with the Giants assuming the roughly $254 million remaining on Devers’ 10-year, $313.5 million contract, which runs though 2033.

The Red Sox were just 36-36 at the time of the trade, the Giants 41-30. Over the remainder of the season, the two teams’ fortunes reversed, with Boston going 53-37 and securing a Wild Card berth, just the team’s second trip to the postseason since winning the World Series in 2018, and San Francisco going 40-51 and missing the playoffs for the eighth time in nine seasons. Each team has changed managers since, with the Giants axing Bob Melvin in favor of Tony Vitello — the rare manager to make the jump directly from the college coaching ranks — last October and the Red Sox firing Alex Cora in late April. Those varying paths have led the two teams to similar spots: the Red Sox are 29-41, last in the AL East, while the Giants are 29-43, two games out of last place in the NL West. (Note that throughout this piece, stats from our site include those from Devers’ two plate appearances in Tuesday night’s suspended game against the Braves, while those from Baseball Savant do not.)
