Jake Bauers, former first baseman of the World Series champion Milwaukee Brewers has agreed to a four-year contract ($58 million) with the Red Sox, according to ESPN's Jeff Passan.
Bauers, 31, had a career-best season with the Brewers in 2026: .266/.389/.484, 26 home runs, 86 RBIs. He was named MVP of the NLCS.
Alex Speier of the Globe reports that Bauers will have a physical next week before the deal is finalized. The contract breakdown:
2027 - $16M
2028 - $16M
2029 - $15M
2030 - $11M
Theo DeRosa, mlb.com:
Prior to 2026, Bauers, who made his debut for Tampa Bay in 2018, had a career .211 average and .672 OPS with the Rays, Guardians, Mariners, Yankees and Brewers. . . .
[In 2026], Bauers hit the ball harder than ever, increasing his barrel rate to 14% and reaching career highs in his average exit velocity (92.1 mph) and hard-hit rate (51.9%). According to Statcast, he ranked above the 90th percentile among qualifying hitters in all three of those categories as well as expected wOBA, average bat speed and chase rate.
Bauers' refusal to expand the zone explains his career-best 16.3% walk rate, which ranked in the 98th percentile, although he still whiffed a lot and had a high strikeout rate (27%, 16th percentile). While a majority of his home runs came to the pull side, Bauers still showed the ability to go up the middle or the opposite way for singles and doubles.
A collection of thoughts from SoSH (I seem to have preferred comments that view this as a positive signing because they offered more insight and reasoning, which tells you something):
The upside is certainly there as a power bat if is 2026 can be replicated.
Any reason to think 2026 wasn't a fluke / career year / outlier?
FWIW, my recollection is he has pretty good pedigree/was a relatively highly ranked prospect. So, late bloomer hopefully,
How much has to do with organizational hitting coaching/philosophies and will Bauers get that in Boston?
Whoa! That came outta nowhere. Well, we got some power. And the AAV is nice.
If you believe the breakout this could be unreal.
He'll be 31 all season. Honestly, the deal just feels super light and a no brainer at this costs.I like it. Second in NL in OBP last year. 30-HR power. Of course he's only done it one year, but the cost reflects that and feels pretty reasonable?
Much as I like him, I don't think Casas should be counted on for anything. …
Masa and Duran should not prevent the Sox from improving offense.
Bauers is better and more valuable than all of these guys. I support bringing in guys that improve the Sox, and figuring out how the pieces fit after.Savant has Fenway Park as the worst fit for his HR power in baseball.
Kind of the same thinking as the Mead acquisition. A player who has struggles has a breakout year or half year and Boston bets that the relatively SSS is indicative of the true level of performance.
Sad that this takes Suzuki off the table. He's not going to hit 30 HR at Fenway but he will bounce plenty off the monster - better oppo air% than all our lefties but Abreu. Seems like a smart hitter too. He had some ridiculous long ABs in the NLCS.
I'm very happy with the move. I mentioned him as the guy I hoped they'd get since it was a realistically available bat at one of the few easy to upgrade positions. I didn't see them being the high bidder for Suzuki and they've got little to move from the farm.
His 2025 stats were not great but his underlying data was pretty much the same as it was in 2026. I think he started to break out in 2025, he just was unlucky and did not get the playing time because Vaughn was hitting well for the Brewers in 2025.
He doesn't chase, he has great bat speed, and hits everything hard. His AAV is 2/3 of the QO and he's not exactly old. I'm failing to see what the problem is here.He also had a 35 point jump in BABIP over 2025, which had been a career high by 10 points. Im not someone who can say that's meaningful or not, but it jumped off the stat page to me.
I don't understand the hate here. >15 mil per year to someone with 25-30 HR power? I think that's a very reasonable contract, for someone that fits well in our lineup.
No hate here. in 2026 $14 mill is not a hefty gamble. I'm fine with it...provided the right 2nd and 3rd moves follow.
Career year going into free agency. This is one of the dumbest contracts this organization has ever done. He's not a 25-30 HR guy.
I don't think a deal under $60m could ever be one of the dumbest things they've done. That's less than Rusney got!
It's probably not even the top 5 worst contracts we've signed in the last 2 years.
The Sox are adding MLB depth to a roster that was running on AAAA talent into the playoffs. Its also not money that belongs to any members here so I don't get any handwringing. We should want the Sox to have logjams of MLB players for not only depth reasons but also because it gives them currency to add other pieces.
No complaints here. Keep adding MLB talent and let the normal injuries, attrition, fatigue etc sort it all out.If he plays at the same level he did in 2025, over more ABs of course, it's still a decent deal ... it just probably doesn't move the ball forward for us offensively. So that's the risk to me: there's a chance he flops, sure, but there's also a chance he's not as good as last year but is passable and we still need better than that.
He's not just bringing power: Bauer is an extremely patient hitter who runs very high walk rates. He had a .389 OBP last season, which would have far surpassed every RS hitter except Contreras (who was .386). After the playoffs this board was pining for more patient hitters in the lineup and Bauers provides that in spades
[Breslow]'s building depth, which is always a good thing. And agree on the quality of ABs. Bauers style is lacking on this team. And the Brewers just proved that you don't need a fantasy baseball lineup to win. Building as solid a 1-9 is just as viable a strategy, especially since obtaining a star is near impossible these days.
The thing is...Milwaukee is the first place he was able to spend more than one season at. And he got progressively better every season while there. Makes me wonder if a big part of his development was having consistency not only in enviornment, but with the coaches who were watching him...working with him...developing him. . . . I can buy this being real. Sure, I expect some regression. But can he remain a .245-.250 hitter who gets on base 35%+ of the time and hits 20-22 HR? And for everyone saying he isn't a 20+ HR hitter historically, he has hit 1 HR every 30 plate appearances over his career. Projecting over full seasons, that's 20 HR.
I'm shocked that so many people are against this. He was a former top prospect who became a late bloomer. He had an amazing Sept. 2025, so it's a little more than 1 year breakout. He is patient (we need that), has power (we need that), goes the other way in the air to use the Monster (we need more of that), plays a good 1B so he can split 1B/DH with Contreras and hopefully keep Contreras healthier down the stretch. He can also spell a corner outfielder if needed. Great OBP guy. And the contract is actually very reasonable by today's standards. I would think this means Duran and Yoshida are gone, which actually will help the roster.
Since 2023 he's posted an xwOBA of .345. 2025-2026 was very good but 2023 wasn't bad either. You hope he replicates something like that.
They're definitely taking the throw-spaghetti-at-the-wall approach to see what sticks.
But I would rather that than they did nothing. You've now got a lot of guys between Roman, Mead, Bauers, Arias, and Rutschman (and even Campbell) who have tremendous potential and have had very good years, but who have also had down/disappointing years...
but we really just need some of them to hit in order for things to go our way, IMO. It's not a bad approach to building an offense. It's certainly better than doing nothing.
EDIT: What I like most with Bauers is the elite patience. 16.3% BB rate last year after 14.7% the year before. We desperately needed good at-bats. He gives great ones.

Ben's Take [ranks Bauers #12 on list of 2026 FA]
Every time I updated my view of this free agent class throughout the year, I moved Bauers up. In the end, I might have gone too far by floating him all the way up to the top 12, but I kept looking at the players I had ranked ahead of him and thinking "Man, I'd rather have Bauers." Bauers comfortably clears the "first base dead zone" – a wRC+ in the 105-115 area – that feels easily replaceable on the waiver wire or from the minor leagues. He's the best lefty slugger on the market, and he's not that far behind Suzuki as the best slugger overall. He's going to crack a few strikeout eggs while he makes his walk-and-home-run omelets, but he's not just up there hacking with no idea of what's going on. He has great plate discipline and his contact numbers aren't abysmal; he's just patient and willing to work deep counts waiting for a pitch to drive.
The reason to fade Bauers is the lack of track record. He posted 3.6 WAR this year – and he has 3.2 career WAR. That's cause for skepticism. But my projection is for a skeptic's contract: not too many years, not too much AAV, easy enough to walk away from if things don't pan out. And when I looked at it that way, I had a much easier time placing him on this list. . . .
Player Notes [Oler]
Bauers' free agency will depend heavily on how much teams believe that the left-handed first baseman flipped a switch in September of 2025. . . .
Bauers now has two seasons of above-average hitting on his ledger . . . His expected stats have trended upward alongside his actual results, lending credibility to his newfound productivity. The "no thoughts, head empty" approach has led Bauers to more selective swing decisions. He's whiffing less on pitches outside of the zone and doing more damage on pitches in the zone and just above it. Simplifying his mental process has translated to fewer strikeouts, more walks, and improved contact quality. Further, Bauers did supplement his internal approach with some external tweaks. He moved back in the box and opened up his stance, allowing even more time for those crucial swing decisions.
Bauers doesn't dazzle on defense, but given that he posted the fourth best wRC+ (143) among qualified left-handed hitters in 2026, Brewers skipper Pat Murphy appears to be correct in his assessment that Bauers is about to be very rich, whether he signs with the "horseshit Yankees" or not.
