ANAHEIM -- Rangers outfielder Josh Hamilton moved from center to left in the fifth inning and then exited entirely in the bottom of the seventh Friday night because of right patella tendinitis.
Hamilton has battled tendinitis in the knee this season and said he would arrive early for treatment on Saturday in hopes of returning to the lineup.
"Just calling it tendinitis right now," said Hamilton, who was 1-for-3 with an RBI, a run and a walk in the 9-7 loss. "It was just hurting before everything started up today. Before batting practice, before everything. The pain part doesn't bother me, it's just [the possibility of] giving out on me and not working -- I don't want to be out there, especially in center field, in an important spot in the field."
Hamilton said there was no trigger moment that pushed him out of the game. He's already received one cortisone injection this season and said he's open to another but would leave that to the judgment of the team's medical staff. Because he's already received numerous cortisone shots in his career, he said he would not have to wait 24 hours after receiving the shot before playing.
"We'll know more tomorrow," manager Ron Washington said. "He came in on the one ball [a single by Alberto Callaspo in the fourth inning], and it sort of tweaked on him a little bit. We'll know more tomorrow."
