"Hopefully, the cast will be off in 3-4 weeks and then start my rehab from there," Olt said. "It shouldn't be too hard of a rehab, get my arm ready. The wrist should be feeling better they said by then."
Olt was injured when he was hit by a pitch on the wrist on April 11 against the Rockies. After that game, he played with the injured wrist, going 0-for-3 as a pinch-hitter and made two appearances at third base.
"It wasn't fun," he said. "It could have been a lot worse. At the end of the day, even though I'm in a cast, I just have to look at the positive. Nothing structurally wrong with ligaments or anything like that."
Olt saw a hand specialist on Thursday that revealed the damage.
"We did a different kind of X-ray when I was in Colorado, and my pain wasn't too bad, so I guess we didn't look into it further and then it just didn't progress as well as we thought, so we did an MRI," Olt said.
Olt is 2-for-15 with one home run this season.
"It's disappointing," Olt said. "Obviously, you work hard in the offseason to play and you want to play the whole season. It happens in baseball. There's nothing you can do, nothing I could have done differently that wouldn't allow this to happen."
