The Seattle Mariners made a significant move by claiming outfielder Leody Taveras from the Texas Rangers, a rival in the American League West. Taveras, who played a crucial role in the Rangers' World Series victory against Arizona, has been inconsistent this season, batting just .241 with one home run and six stolen bases in 30 games. The Mariners are assuming the remaining $3.25 million on his contract, hoping to revitalize his career.

In other roster adjustments, utility player Dylan Moore has been reinstated from the injured list, while Samad Taylor has been optioned to Triple-A Tacoma. Right-hander Luis F. Castillo has been designated for assignment after struggling with a 7.71 ERA in his two starts this season. Moore was performing well before injury, boasting a .286 batting average with six homers and nine RBIs, indicating the Mariners’ intent to strengthen their lineup.
