Freshman right-hander Josh Collmenter went eight and two-third innings for the win while sophomore lefty James Ricchio picked up his second save by getting the only batter he faced.
The win upped the Chippewa record to 29-15 for the season and 11-6 in MAC play. The Broncos fall to 21-17 overall and 11-4 in MAC action.
Collmenter scattered 11 hits in his outing and raised his record to 6-1 with a 2.31 ERA.
The Chippewas grabbed a 1-0 lead in the second when Sean Hoorelebeke tripled to center and scored on Jeff LaFavors' single to right.
The Broncos tied it in the sixth when Travis May walked and eventually scored on a single by Mark Abro.
Central Michigan came right back in the seventh with three runs off Western Michigan starter and loser Dan O'Brien (2-3). Brian Campbell had a one-out infield single and Troy Moratti followed with a single to center. J.T. Jones then doubled down the right field line, scoring Campbell and Bryan Mitzel followed with a two-run double over the centerfielder's head that plated two more.
WMU added a run in the ninth on doubles by Nathan Marquardt and Adam Rosales, the last one chasing Collmenter. Ricchio then got Travis May to bounce out to third.
Jones had four hits in four at-bats to raise his average to .310. LaFavors was the only other Chippewa with multiple hits, a pair of singles.
Justin Carter and Abro had two each for the Broncos.
The final game of the series is set for here Sunday at 1 p.m. It will be Little League Day and all little leaguers and their coaches in jerseys will be allowed in for free. There will be an autograph session following the game.
