The Seattle Mariners confirmed Monday evening that they have acquired All-Star infielder/outfielder Brendan Donovan from the St. Louis Cardinals.
A source spoke to the AP on condition of anonymity on Monday because the teams had not yet finalized the trade, but by 6:30 p.m. that same night, the Mariners confirmed the trade.
“We have acquired All-Star INF/OF Brendan Donovan from the Cardinals. In exchange, we have traded INF Ben Williamson to Tampa Bay and minor league RHP/LHP Jurrangelo Cijntje, OF Tai Peete and a 2026 Comp Round B draft pick to St. Louis,” wrote the Mariners in a social media post.

Donovan, 29, was a first-time All-Star last year, when he hit .287 with 10 home runs, 50 RBIs, and a .775 OPS.
Over a four-year major league career, he has hit .282 with a .772 OPS, 40 home runs, and 97 doubles.
Donovan also won a utility player Gold Glove as a rookie in 2022.
He is reportedly playing on a $5.8 million, one-year contract, and is eligible for arbitration again next winter and is on track to reach free agency after the 2027 World Series.
Donovan could fill a middle-of-the-order role similar to what Jorge Polanco provided last season.
Polanco hit 26 home runs, then became a free agent and signed a $40 million, two-year contract with the New York Mets.
Seattle finished last season one win short of the franchise’s first World Series appearance.
