Hamilton, who leads the majors with a .361 batting average, was the designated hitter the previous two games at Kansas City. He hit .435 with five home runs and 16 RBIs in his past 12 games and said he planned to play the outfield Friday.
"I would say I'm 40 to 50 percent better," Hamilton said Wednesday. "I've got two days off here, which will be good. I'll just come in on Friday (after an off-day Thursday) and do all the normal stuff, but I will take it easy the next two days, just kind of rest it. I'll just try to get through it for a couple of weeks and see what happens."
Hamilton said there is a possibility for another cortisone shot in a couple of weeks. He is among the American League-leaders with 31 home runs, 40 doubles and 97 RBIs.
"It's like having a toothache," Hamilton said. "It hurts all the time. It's that time of year. Just walking around it feels better. That says something. It was bothering me sleeping. I slept better last night."
