One of the biggest offseason deals so far has been the Seattle Mariners acquiring center fielder Leonys Martin from the Texas Rangers. The Mariners were in desperate need of a defensive upgrade in center and Martin had fallen out of favor with the Rangers after struggling with injuries and the bat in 2015. With the emergence of Delino DeShields in center, plus Nomar Mazara on the way, there wasn't room for Martin in a crowded Texas outfield and he was a non-tender candidate.
Mariners GM Jerry Dipoto pounced quickly in the offseason, getting Martin for reliever Tom Wilhelmsen and corner infield prospect Patrick Kivlehan.
