Right fielder Chance Bolcerek tripled to left center with one out in the fourth inning then scored on a sacrifice fly by left fielder Brandon Wood to extend the Aggie lead to 2-0.
A&M loaded the bases again with no outs in the top of the fifth on consecutive singles by designated hitter Mitchell Nau, shortstop Mikey Reynolds and second baseman Scott Arthur. All three scored on Bearkat walks and pinch hitter Matt Juengel singled in another run.
The Aggies added single runs in each of the next three innings.
