Caleb Durbin will open the season as Boston's starting third baseman, the Red Sox confirmed Tuesday. The 25-year-old infielder, acquired from Milwaukee in a trade finalized before spring training, replaces Alex Bregman, who signed with Chicago as a free agent. Durbin, who has been splitting time at the position with Marcelo Mayer this spring, expressed enthusiasm: 'I love third base. I'm excited.'

Durbin's spring training performance has solidified his position. He's hitting .394 in 33 at-bats, with 7 RBIs and 3 stolen bases, showcasing both his bat and defensive skills. This marks a significant upgrade from Mayer, who is hitting just .250 in 24 at-bats with a home run and 2 RBIs. Durbin's acquisition and immediate promotion underscore the team's strategy to stabilize a key position after Bregman's departure.

Durbin's 2025 season (.256 average, 11 homers, 53 RBIs) earned him third-place in NL Rookie of the Year voting. His strong showing in spring training, combined with his experience from winning Milwaukee's third-base job after the Devin Williams trade, makes him the clear choice for Opening Day. The Red Sox now look to Mayer at second base, with Story and Contreras anchoring the infield.
