"I haven't thrown in over a month now," Guerrier said. "I could still feel it when the doctor pushes on it, but the last few days have been better. When I start to get my head around the possibility that I'll need something [surgically] done, it starts feeling better, then I'll have a bad day again. The hardest part is that it's not consistently good or bad."
Guerrier said if he's not able to throw by the end of July, he will probably submit to repair surgery that would sideline him for six months.
"I just want to be able to pitch again," he said.
