Hammel said the doctor said the problem with his knee -- which had an arthroscopy done on it in mid-July -- was what the doctor called a "hot spot" and probably needs some time to calm down. Rest and strengthening the knee will be what Hammel works on for the next several days.
But Hammel couldn't pinpoint a return date. Still, he was happy that there's no new troubles with the knee.
"I was pumped to hear [this news]," he said after Thursday's game. "I thought something else was going on just by the way it felt and even from the pain I felt [Wednesday] -- and the improvement into today was significant. It's making strides."
Hammel came out of Tuesday's game with the Rays in the fourth inning when he felt pain in that knee. He headed out west with the Orioles and said he wants to return as soon as possible. For now, he's going to continue the treatment and keep pushing.
"I want to get back out there as soon as I can," Hammel said. "But obviously, if I can't use my leg, I can't pitch. If I can get back at any point this season, I'm going to."
