This is a thing too, from the Strib http://www.startribune.com/twins-reach-deal-with-marwin-gonzalez/506221452/ : Adrianza is still not 100 percent following offseason surgery on his left shoulder. The injury affected Adrianza’s follow-through while batting righthanded, forcing the switch-hitter to bat lefthanded against lefthanded pitchers during the final weeks of last season. He’s been icing the shoulder since arriving at camp and will only bat lefthanded during spring training games. Surgery took place on Oct. 9, and he was told recovery would be six to eight months. “Everybody knows I can’t hit righthanded right now,” Adrianza said, “so they might have to figure out who’s pitching to decide if I play.” I didn't know he was not 100%.
