Victor Martinez is thrilled to be in Detroit, where he'll primarily serve as the team's designated hitter. Martinez received advice from former Cleveland teammate Travis Hafner. "He told me that you have to do a lot. Maybe people think that it's easy to be a DH. It's hard," Martinez said. "You have to keep warm. You've got to go into the weight room and run the bike and do stuff, stretch yourself. You can't just sit there for a half an hour, an hour, until you get at bat again and just go out there and hit. It's not like that."
