"I'm ready," Crain said. "It's to the point where I can do regular stuff or else I wouldn't be here."
Crain made just one appearance on Feb. 25 until the final week of Spring Training because of that injury. But he pitched his way on to the active roster in that last week, a valuable late-inning component because of his ability to retire left-handed hitters as well as right-handed hitters.
"[Pitching coach Don Cooper] and Robin obviously have my back and they wanted me to be here, which makes me feel good," Crain said. "I knew it wouldn't take long for my arm to be in shape. I just waited for my leg.
"It took time building my leg to be able to trust it. The last outing [in Milwaukee], I was able to prove I don't think about it and go right through it."
