That's true, he did have some freak injuries last year. But he was beaned in the head which kinda made him trigger-shy all season, and the bone chips in his elbow has subsided. Also, 1B is an easier position to fill, I guess. But it's not like he is a seasoned veteran. This is his third season (2nd full year), and he was born in 1981.
His prime will be coming in 2 - 3 years from now. If he stays healthy, and bats cleanup, can you imagine the potential?
My Bad - this is his 4th season (in his second season, in 280 AB's, 19 HR's).
