The Governors used the long ball to take control. David Martinez hit a two-run shot in the second to make it 3-2. Aaron Campbell hit a three-run homer with two outs in the third to extend the margin to 6-3 and give APSU the lead for good.
The Colonels scored three times in the seventh to get back into the game.
With the bases loaded and one out, Brewer doubled to center to score a pair. Charles Ludwick scored later in the inning on a dropped third strike to make it 8-6.
EKU (31-26) loaded the bases with one out in the top of the eighth, but couldn't bring in the tying runs. The Colonels drew within two runs again in the ninth, 9-7, on a two-out RBI single by Harris, but left the tying run at first base.
EKU stranded 17 runners on base in the game.
Brewer finished 2-for-3 with three RBI. Johnson had a 2-for-4 day with a walk and a run scored. A.J. Lewis went 3-for-5 and scored twice.
Parker Phillips was 3-for-4 with two runs for Austin Peay (32-23). Campbell went 3-for-5 with two runs and five RBI.
"It was a good battle," EKU coach Edwin Thompson said. "We came out early and kind of established ourselves, but they did a good job of silencing our bats through the middle of the game. They stayed consistent throughout the whole game. We couldn't get a stop until it was too late and offensively, we just didn't have enough big hits."
