It's not the first time Collmenter has accomplished that this year. In the season's third game, he turned in a five-inning relief outing in a 16-inning win over the Cardinals at Chase Field.
Collmenter played catch Wednesday afternoon and said he felt good, but the team is likely to give him a few days off before using him again in a game.
"I was joking with the guys, just got to squirt a little oil in the arm and 'Iron Mike' is good to go," Collmenter said. "If needed, I could throw, but I'm sure they'll give me a day or two and make sure I'm ready to go by then and be 100 percent."
Despite the fact that the game ended in the wee hours of the morning, Collmenter stuck around the clubhouse for a while, going through his normal postgame exercise routine so as to make sure his arm would recover even faster.
"They asked me if I felt good, and I was going to go back out there for another [inning] if we didn't take the lead," Collmenter said. "After that it would have been an inning by inning basis, but up to that point I felt really strong. I didn't really feel any fatigue or anything."
