The two teams battled to a 22-22 tie in the first half before Cornersville surged out to a 35-28 lead early in the fourth quarter.
Culleoka (2-8, 0-4 District) rallied to tie the game at 41-41 with 3:59 left, but the Bulldogs kept plugging away and outscored the Warriors 7-2 down the stretch with the help of some clutch foul shooting by sophomore point guard Tate Lowery to pull out the five-point victory.
Thanks to Friday's triumph, Cornersville snapped a 24-game losing streak and recorded their first win in District 11-A play since beating Hampshire 57-50 on Feb. 5, 2010.
"It feels great to get a win. I got so caught up in the game that I didn't realize it was over until the final horn sounded. When I heard it go off, I just thought 'We did it!' It feels like a weight has been lifted," said Randolph. "The fact that it was a District win means a lot too. After the game, the players were already talking about practice and preparing for the next game. Hopefully we can build on this."
Although Culleoka finished with a 17-15 edge in field goals and an 8-4 advantage in three-pointers, the Warriors struggled mightily at the foul line and hit just 1-of-13 free throws overall, compared to a 14-of-23 effort at the charity stripe by the Bulldogs.
