"(It was) a stupid play," Hamilton told the team's website (texas.rangers.mlb.com). "I definitely shouldn't have gone. I was thinking, 'I don't want to do this. Something is going to happen.' (But) I listened to my coach."
Hamilton, the Rangers' left-handed slugger, batted .359 with 32 home runs and 100 RBIs last season and helped Texas to the World Series despite missing a significant number of games in the stretch last September with a rib injury.
It is the third time in the last three seasons he has been placed on the disabled list.
