Columbia held a tenuous 3-2 lead through the first five innings of Monday's contest before crossing home plate three times in the top of the sixth to pull away for the four-run victory.
Cornersville finished with seven hits and a walk against Lady Lion starting pitcher Baylee Terranova, but went 1-for-10 with runners in scoring position and left eight women on base overall.
Makayla Campbell, MandiLynn Calahan, starting hurler Taylor Wolaver, Makenzie Hopkins, Kaitlyn Rogers, Brittney Crowell, and Kelsey Wortham notched one hit apiece for the Lady Bulldogs with Hopkins and Rogers each scoring a run.
Wolaver, meanwhile, suffered the loss in the circle after allowing six runs in seven innings of work on 13 hits and four walks to go along with four strikeouts. Cornersville's defense also made Wolaver's task tougher by committing three errors.
Terranova (1 RBI), Kelly Merkel (2 RBI), Delaney Hudson (1 RBI), Dareain Baker, Imani Carter (2 RBI), and Takoya Lyles each had two hits for Columbia with Merkel belting a two-run homer in the sixth inning.
"We beat ourselves again. We made too many mistakes and didn't get enough timely hits. If you don't commit errors, you can keep the game close," said Lady Bulldog coach Eric Crabtree. "We hung our heads a little bit too after that girl hit that homerun in the sixth inning. We've got to learn to fight a little bit harder when we're down."
After Wolaver worked around a pair of two-out singles by Terranova and Merkel in the top of the first inning, Cornersville was unable to capitalize on a leadoff single by Rogers in the bottom of the second and stranded a runner at third.
Columbia's offense then heated up in the third inning, as they crossed home plate three times in the frame on the strength of a Terranova RBI double and a couple of RBI singles from Hudson and Carter to grab a 3-0 lead.
The Lady Lions had a chance to pad their lead in the fourth after putting runners on second and third with one out, but Wolaver retired the next two Columbia batters on a strikeout and a lineout to escape the inning unscathed.
In the bottom of the fourth, the Lady Bulldogs whittled the deficit to 3-2 by pushing across two runs in the frame thanks to three Lady Lion errors, a RBI fielder's choice by Breanne Dunkleman, and singles from Hopkins, Crowell, and Wortham.
Columbia left two women in scoring position in the top of the fifth, but opened up some breathing room in the sixth and plated three runs in the inning on the strength of a two-run shot by Merkel and a Carter RBI single to forge a 6-2 advantage.
Terranova then worked around a leadoff walk by Crowell in the bottom of the sixth, before Cornersville stranded a runner at third in the seventh after Campbell led off the inning with a single.
