David Hall doubled home Clay Holcomb in the home half of the first inning and Matthew Howard later singled to score Hall and Jo-El Bennett. That would be all the offense Troy needed as starter Cody Hughes combined with three relievers to slow down the Chippewas (2-6) offense.
Hughes pitched four innings allowing two earned runs on three hits. After Hughes allowed consecutive base runners in the fifth, he gave way to Jeremy McGowan, who surrendered a pair of soft singles allowing the two runs to come across. McGowan (1-0) would settle down and pitch 2 2/3 innings striking out four and would pick up the win on the mound. Freshman Marc Skinner picked up his first save of the season getting the final out of the eighth and tossing a perfect ninth.
Troy (5-3) would pick up all three runs and eight hits off CMU starter Adam Aldred (0-2). Morgan Oliver and Nick Regnier were the only Chippewas to record two base hits.
The game was delayed in the seventh inning due to rain but resumed 13 minutes later.
With the win, Pierce not only picked up win No. 400 at Troy but No. 935 in his career. The coach, now in his 12th season at Troy, is just 34 wins away from breaking Chase Riddle's school record for wins (434).
Howard and David Hall finished with two hits each for the Trojans while Holcomb, Bennett Garrett Pitts, Nick Masonia and Tyler Vaughn also picked up base hits.
The Trojans will travel to Florida A&M on Tuesday for the team's first road game of the season. Game time is set for 3 p.m. (CT).
