Collmenter is coming off his best start of the season (and one of the best in the majors so far) in San Francisco, in which he went the distance and allowed only four hits in a complete game shutout against the Giants. This was a welcome sight after the right-hander allowed seven runs in his previous two starts combined, where he was unable to pitch past the sixth inning in either start.

In five games against the Pirates (two as a starter), Collmenter is sporting a 2.70 ERA. Andrew McCutchen is 1-7 off of him with two walks, and Josh Harrison is 0-5.
