For the 20th 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

As last-place teams go, the 2023 Red Sox were a pretty good one. Nobody puts a 78–84 season on their sizzle reel, but they played adequate baseball for most of the season, enough that they hovered two to four games out of a wild card spot for a large chunk of the summer. An 8–19 September suffocated those chances, but Boston still managed to have an 81–81 Pythag record. If the Red Sox played in a Central division, they would have been competitive for even longer. But Boston’s coastline is on the Atlantic Ocean, not a Great Lake, so this is where they compete.

The offense highlights the awkward situation the Sox are in. They may be happy with the value they got for a year of Mookie Betts, but he offers something that the Red Sox don’t have: someone who can go out of their minds for a year and put an 8–9-WAR season on the leaderboard. Rafael Devers is very good, and one of the premier power-hitting third basemen of this generation; ZiPS gives him a final median home run total among his active compatriots at the hot corner (442) that’s behind only Manny Machado. But he’s not a multi-dimensional all-around monster. Nor is Trevor Story going to fill that role, even if he has as juicy a comeback season as ZiPS thinks he will. Triston Casas should be good as well, but the rest of the roster is just “there.” To upgrade on this group, you need to find 3–4-WAR players, and those don’t come cheap. Boston would be better off with a few more sixes and zeroes on the depth chart.

On the plus side, some of the reinforcements may help, with ZiPS finding a lot of interesting possibilities in Boston’s top prospects. Ceddanne Rafaela didn’t hit in his brief debut, but my Total Zone-esque coordinate measurement system had him as the second-best center fielder in the minors, behind only Jorge Barrosa. ZiPS also already has Marcelo Mayer at the two wins-per-600 PA threshold in 2025 and is certainly more into Kyle Teel than Steamer is. But like the main offense, there just isn’t that phenom guy, though Mayer could take a big step up if his shoulder doesn’t give him too much more trouble. This isn’t a great offseason to make big offensive additions via free agency, and given how the Red Sox have been run in recent years, I can’t imagine they’ll go into any rentals.

Pitchers

The story here is similar. The Sox aren’t bad anywhere, but there just isn’t a tremendous amount of upside either. Expecting Chris Sale to channel the old Chris Sale for 160 innings is a big ask, and Brayan Bello looks more like a good number two than an ace for the franchise that had Roger Clemens and Pedro Martinez. With Steamer, we have the Red Sox rotation as the middle of the pack, and I don’t think anything ZiPS is saying here will change that. On the good side, there are quite a few above-replacement Plan Bs, Cs, and Ds for the rotation — necessary given the injury history of several of the starters — but nobody with amazingly high potential. And maybe someone like Wikelman Gonzalez will change that, but it’s a little too soon for projections to see that as a median outcome. This is one place I can see the team spending some money this winter.

When Steamer came out, I was a little surprised to see the Red Sox projected as a top-10 bullpen, but ZiPS actually agrees with that. I suspect Garrett Whitlock is likely to stay in the bullpen from here on out — this has not been confirmed as far as I’ve seen one way or the other — and as a full-time reliever, ZiPS sees him with an ERA in the low threes. Chris Martin joined the team in a whisper on a two-year contract last offseason and served as one of the team’s indispensable parachutes, with an ERA just over one. Clocks are a concern given his age, and there’s a clear warning sign in the strikeout rate decline, but he should still put hitters in their place for another season. As veteran relievers go, ZiPS isn’t as confident about Kenley Jansen given his age and some erosion in his peripheral metrics, and I’d like to see the Red Sox slowly transition their closer job to Whitlock if they keep him in relief. The bottom of the ‘pen isn’t exciting, but it’ll get the job done.

The Red Sox look like an 80–86 win team or so. That kind of team can surprise, and with the coins flipping a bit different last year, they could have made a real wild card run. The Orioles, Blue Jays, and Rays are a clear tier above them, though, and when all is said and done by winter’s end, I think the Yankees may be as well. But that last question is a tale for another ZiPS entry.

Players are listed with their most recent teams wherever possible. This includes players who are unsigned or have retired, players who will miss 2024 due to injury, and players who were released in 2023. So yes, if you see Joe Schmoe, who quit baseball back in August to form a Belgian Death Metal Skiffle Band that only plays songs by Franz Schubert, he’s still listed here intentionally. ZiPS is assuming a league with an ERA of 4.33.

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.

As always, incorrect projections are either caused by flaws in the physical reality of the universe or by the skillful sabotage of our friend and former editor. You can, however, still get mad at me on Twitter.
