In reality because the new coach apparently has some screwed up problem with taking pitchers out. He has been known this season to leave them in far too long, and the team has suffered because of it for the most part.

On the other hand the kid was dominating the Rutledge hitters in the first game that PF won 15-2. He went six innings and they only scored two runs. I guess the coach could have thought "if it ain't broke, don't fix it" because in the second game he went five scoreless before he was pulled. Pf then brought in a freshmen lefty that Rutledge couldn't hit either.
