While new Mariners infielder Robert Andino played mostly second base with the Orioles over the past two years, the 28-year-old considers himself a shortstop first and foremost. Andino started 106 games last season for the Orioles, including 96 at second base. "The addition of Robert Andino gives us some experienced infield depth with a player who has played multiple positions," said Mariners general manager Jack Zduriencik. The trade was made Tuesday and instantly gives the Mariners an experienced infielder who can play second base, third base and shortstop. Andino thus is a solid utility-infield candidate, a definite upgrade over the light-hitting Munenori Kawasaki. The Mariners also will bring No. 3 prospect Nick Franklin to camp on a non-roster invitation, though at 21 years old and having hit .243 in 64 games after a midseason promotion to Triple-A Tacoma last season, he might still be a year away. He started 233 games for Baltimore over the past two seasons, mostly at second base and shortstop, and earned $1.3 million last year in his first season of arbitration eligibility.
