2025 ZiPS Projections: Boston Red Sox

For the 21st consecutive season, the ZiPS projection system is unleashing a full set of prognostications. For more information on the ZiPS projections, please consult this year’s introduction and MLB’s glossary entry. The team order is selected by lot, and the next team up is the Boston Red Sox.

Batters

I have mixed feelings about the Red Sox. As a baseball fan, it galls me to see Mookie Betts in another uniform, and their complacency these past few trade deadlines has been frustrating. Yes, it’s good that they extended Rafael Devers to a long-term deal, but more often than not their forays into free agency end up in the We Tried bin.

But at the same time, even though Boston isn’t throwing its weight around like most large-market teams, this is a highly competent organization that makes smart moves. The Red Sox have developed a significant number of players internally – and more are on the way – and they’ve put those players positions to succeed. I have to admit that Jarren Duran and Wilyer Abreu have become far better than I expected, and though the experiment of moving Ceddanne Rafaela back to shortstop in the majors didn’t really work out, his upside was worth the gamble.

If anything, the Red Sox now look a lot like a 2010s St. Louis Cardinals roster. Not a single player in the lineup is projected to be an MVP candidate – no, ZiPS is not that high on Duran – but by the same token, almost every player is projected to be average or better, with decent depth at most positions. Even at catcher, which is projected to be their worst position (now that they’ve traded Kyle Teel), the Red Sox should get an acceptable level of mediocrity.

ZiPS holds out hope for Rafaela being just good enough offensively for his glove to play, and his WAR projection is a full win higher in center field than it would be at shortstop. A Trevor Story revival would be nice, but ZiPS isn’t particularly taken with him these days, and David Hamilton actually has a similar projection. It’s not something they’d announce, but I suspect the Red Sox would be happy to see Marcelo Mayer seize the shortstop job soon. At second base, ZiPS thinks Kristian Campbell would be one of the most accomplished offensive players to debut in the majors in 2025. Campbell and Roman Anthony project to be Boston’s third- and fourth-best offensive players, respectively.

Pitchers

Naturally, ZiPS doesn’t expect Garrett Crochet to carry an ace’s workload, but if he throws only his projected 135 innings, he should still be the best member of Boston’s rotation, which also features Tanner Houck, Kutter Crawford, and Brayan Bello. That group looks like one of the better starting staffs in baseball, though it’s a tier below the elite rotations of the Phillies and Dodgers.

I’m higher than ZiPS on Crawford, but I think it’s right about Houck as a borderline ace and Bello as a solid no. 2 or 3 starter. ZiPS is a bit of concerned with how Lucas Giolito will perform coming back from internal brace surgery, but he and Richard Fitts both project as reasonable fifth starters. Quinn Priester and Garrett Whitlock also project to be decent fifth starters, but Whitlock is also returning from an internal brace procedure, and I expect the Red Sox will use him conservatively once he’s healthy. It seems likely that he’ll see more innings out of the bullpen than in the rotation next season.

The bullpen projects to be solid, though ZiPS doesn’t rank them quite as highly as Steamer does. There’s some natural skepticism about Michael Fulmer coming off injury, and ZiPS is down on Justin Wilson and Luis Guerrero. But after these players, the projections see pretty much everyone else as either good or very good — but not elite — even edge options like Zach Penrod or Priester.

Like those Cardinals teams, these Red Sox can’t do much upgrading unless they get a superstar to raise their ceiling. The big problem here is the Red Sox play in the AL East, not the NL Central. ZiPS projects them to finish with a win total in the mid-80s. That’d be good enough to contend for a playoff spot, but it probably won’t cut it if they want to win the division. Still, considering the Yankees are trying to figure out how to fill the Juan Soto-sized hole in their lineup and the Orioles could be without Corbin Burnes, the Red Sox have improved enough to make those two teams sweat at least a little bit.

Players are listed with their most recent teams wherever possible. This includes players who are unsigned or have retired, players who will miss 2025 due to injury, and players who were released in 2024. So yes, if you see Joe Schmoe, who quit baseball back in August to form a Norwegian Ukulele Dixieland Jazz band that only covers songs by The Smiths, he’s still listed here intentionally. ZiPS is assuming a league with an ERA of 4.11.

Hitters are ranked by zWAR, which is to say, WAR values as calculated by me, Dan Szymborski, whose surname is spelled with a z. WAR values might differ slightly from those that appear in the full release of ZiPS. Finally, I will advise anyone against — and might karate chop anyone guilty of — merely adding up WAR totals on a depth chart to produce projected team WAR. It is important to remember that ZiPS is agnostic about playing time, and has no information about, for example, how quickly a team will call up a prospect or what veteran has fallen into disfavor.

As always, incorrect projections are either caused by misinformation, a non-pragmatic reality, or by the skillful sabotage of our friend and former editor. You can, however, still get mad at me on Twitter or on BlueSky.
