The trade was made Tuesday and instantly gives the Mariners an experienced infielder who can play second base, third base and shortstop. Despite struggling at the plate, Andino has played in 266 games the last two seasons for the Orioles. Andino started 106 games last season for the Orioles, including 96 at second base.
Seattle general manager Jack Zduriencik says the ability to add a versatile infielder with proven experience was appealing.
Robinson played in 90 games over the past two seasons for the Mariners. He hit .215 in his limited major league time, but was caught in a log-jam of outfielders seeking playing time in Seattle.
