Cornersville led for much of the first half, but the Trojanettes (9-1) used a late second quarter surge to take a 28-25 lead into the break. Collinwood then controlled the second half of play and opened up a 52-37 advantage late in the fourth period before claiming the 10-point victory.
Although they shot a respectable 46 percent from the field overall and knocked down 4-of-7 attempts from three-point range, the Lady Bulldogs committed 32 turnovers and made just 7-of-15 free throws.
"We got off to a good start, but when they turned up their defensive pressure we kind of backed off and became passive," said Cornersville coach Micah Landers.
Center Ashley Umbles turned in a solid performance on both ends of the court and led the Lady Bulldogs with 11 points on 5-of-5 shooting to go along with 11 rebounds, six blocked shots and five assists. Brittany Umbles also tallied 10 points, seven rebounds, and three steals, while Kaitlyn Rogers and Brooke Holt each notched eight points. Kaleigh Welch and Breanne Dunkleman chipped in three points apiece for Cornersville as well.
The Trojanettes, conversely, shot a paltry 31 percent (18-of-58) from the floor and made just 3-of-19 attempts from beyond the arc, but turned the ball over only 15 times, hit 14-of-21 free throws, and held a 21-13 edge on the offensive glass despite being outrebounded 30-25 by the Lady Bulldogs overall.
Alexis Haddock paced Collinwood with 14 points and Laken Arnett followed with 12 points. Lexie Risner added eight points for the Trojanettes as well, while Ashley Farmer and Hanna Littrell both had six points.
Cornersville jumped out to an early 6-0 lead thanks to a pair of baskets from Ashley Umbles and a Rogers jumper before Collinwood went on an 11-4 run to pull ahead 11-10 late in the first quarter.
Risner made two free throws to cut the deficit to 16-13, but Brittany Umbles sandwiched a layup and a three-point play around a jumper by Arnett to push Cornersville's lead to 21-15 midway through the second.
Things started to go downhill for the Lady Bulldogs after that point, as the Trojenettes outscored Cornersville 13-4 over the last 3:08 of the first half to seize a 28-25 advantage at the break before tallying the first six points of the third quarter to extend their lead to 34-25.
The Lady Bulldogs narrowed the gap to 36-32 with 3:52 left in the third period on the strength of a Holt three and baskets from Rogers and Welch, but Collinwood responded with a 12-2 spurt to open up a 48-34 advantage midway through the fourth.
Following a trey by Holt, which trimmed the deficit to 48-37, Katie Hanback and Haddock each hit two free throws to stake the Trojanettes to a 52-37 lead.
Cornersville then outscored Collinwood 6-1 the rest of the way with the help of two free throws and offensive put backs by Brittany Umbles and Ashley Umbles for the 53-43 final.
