The Mariners have acquired outfielder Leonys Martin from Texas as part of a four-player trade that sent right-handed reliever Tom Wilhelmsen to the Rangers.
Texas also obtained outfielder James Jones in Monday's deal, and Seattle received right-handed reliever Anthony Bass. It was the third significant trade by new Seattle general manager Jerry Dipoto.
\Martin is coming off a down year with the Rangers but is excellent defensively and likely moves into the starting center field role. Martin played in 92 games, missing most of August and September after breaking a bone in his right hand, but still had 13 outfield assists. Two seasons ago, Martin hit .274 in 155 games and had 11 outfield assists.
Wilhelmsen was 2-2 with a 3.19 ERA and had 13 saves after transitioning into the closer's role late in the season.
