"I feel good, obviously, just from rest," Haren said. "Throwing really wasn't the issue for me. When I went on the DL, it was more precautionary, lack of execution on my part. I'm just getting back to being 100 percent. Obviously, pitching wasn't working for me where I was. I took some time off, I took some medicine. I feel really good now. I'm excited, obviously, to throw a bullpen [session] and stuff."
Before going on the disabled list, Haren was having his worst season in the big leagues, going 4-9 with a 6.15 ERA in 15 starts.
