The Red Sox have agreed to a $58 million contract covering four years with free agent Jake Bauers, adding a hitter coming off a championship season in Milwaukee to a roster that already has an established first baseman, according to reports Friday.
MassLive reported that a source confirmed the agreement. NBC Boston, citing ESPN reporter Jeff Passan, also reported the deal. Bauers hit 26 home runs for the Brewers in 2026 and now joins Boston in its first major move of the offseason.
The addition brings another productive bat to the Red Sox while raising questions about how their existing players will fit together. Willson Contreras was Boston’s primary first baseman last season and remains under contract for 2027. MassLive also reported that Boston began the offseason with a crowded outfield.
A breakout year in Milwaukee
Bauers finished last season with a .266 batting average, a .389 on-base percentage and a .484 slugging percentage, according to NBC Boston. Along with his 26 homers, he drove in 86 runs for a Milwaukee team that won the World Series.
His impact extended into the postseason. NBC Boston reported that Bauers earned MVP honors in the National League Championship Series as the Brewers eliminated the Los Angeles Dodgers. The Red Sox are adding a player whose most recent season included both substantial offensive production and championship experience.
That season marked a significant turn in his career. Boston.com reported that Bauers had considered retiring from baseball in 2024 before becoming one of Milwaukee’s most consequential hitters in 2026. His agreement with Boston follows that resurgence.
Bauers rejected Milwaukee’s qualifying offer before reaching his agreement with the Red Sox, NBC Boston reported. Boston.com described him as the first prominent hitter to leave the free-agent market this offseason, placing Boston among the early teams to make a substantial offensive addition.
How he fits in Boston
MassLive identified Bauers as both a first baseman and an outfielder. Those positions overlap with areas where Boston already has players in place, making his arrival more than a straightforward replacement for a departing starter.
Contreras hit 27 home runs for Boston last season, according to NBC Boston, one more than Bauers hit for Milwaukee. In addition to his contract for 2027, Contreras has a team option covering the 2028 season. The Bauers agreement therefore adds another first-base option without an existing contractual opening at the position.
MassLive’s roster analysis highlighted that overlap, noting Boston entered the winter with an All-Star at first base and an excess of outfielders. Its assessment of the signing emphasized Bauers’ breakout production, ability to reach base and postseason background as reasons for the investment.
For Boston, the reported agreement secures Bauers for four seasons after his strongest recent showing. How that addition affects Contreras and the crowded outfield remains the central roster question surrounding the move.
