SEATTLE -- General manager Jerry Dipoto promised the Mariners would be active in the trade market in August, and he wasted no time backing that up, as Seattle acquired right-handed reliever Arquimedes Caminero from the Pirates on Saturday in exchange for a player to be named later, as well as a conditional player to be named.
Though the non-waiver Trade Deadline passed on Monday, clubs can still acquire players who pass through waivers. Players acquired by Aug. 31 are eligible for postseaon rosters. Right-handed reliever Blake Parker was designated for assignment to make room for Caminero on the 40-man roster.
