But after he was released, everything went back to normal for Collmenter. The ulcers, albeit extremely painful, left no injury from which to recover.
"I've felt fine, it was just getting my energy level back up after the blood loss," Collmenter said. "It was as if nothing ever changed. I'm on the DL but I don't really have to rehab anything. I'm good to go and there have been no setbacks."
The latest step forward for Collmenter was a scoreless three-inning appearance with four strikeouts in a rehab start with the Arizona League on Friday. His next time out, he will try to extend his pitch count and hopefully toss four frames.
"It went well, I was able to get lengthened out," he said. "I tried to make pitches that I would make over here instead of pitches I thought they would swing and miss at or could chase. I tried to treat it like a sequence I would do over here and it went well."
