Head Coach Darin Erstad will hand the ball to lefty Zach Hirsch at 12:05 p.m. tomorrow and the sophomore will look to improve on his 4-2 record. After throwing a pair of seniors in the first two games of the series, Purdue will counter with freshman right-hander Connor Podkul, who is 1-0 on the year with a 2.30 ERA.
