Giants, Mariners lead chase for All-Star Brendan Donovan from Cardinals.

The San Francisco Giants and Seattle Mariners are reportedly front-runners to acquire All-Star infielder Brendan Donovan from the St. Louis Cardinals. The 28-year-old, who earned his first NL All-Star nod last season, posted a .287/.353/.422 slash line with 32 doubles, 10 homers, and 50 RBI in 118 games. Known for his versatility, playing primarily second base in 2025 and left field in 2024, Donovan is arbitration-eligible through 2027. The Cardinals are seeking a significant return, with Giants prospects Carson Whisenhunt and Gavin Kilen reportedly discussed.
