Culleoka (6-14, 2-7 District) was coming off a stunning upset victory over three-time District tournament champ Mt. Pleasant four days earlier, but were unable to carry that momentum into Tuesday's contest, as Cornersville built an 18-8 lead in the first half.
The Warriors then rallied to tie the game at 26-26 early in the fourth quarter, but the Bulldogs (4-15, 3-5 District) showed their resolve down the stretch and outscored Culleoka 22-16 the rest of the way with the help of some clutch foul shooting by point guard Tate Lowery to pull out the six-point win.
With Tuesday's triumph, Cornersville moved into a tie for fourth place in the District standings with Santa Fe.
"I told the guys that from here on out we have to play every District game like it's our last game. Every win we get in the District helps our seeding in the tournament," said Bulldogs coach Gerard Randolph. "At halftime I told them that Culleoka would make a run in the second half, but we would just have to punch back. I was very pleased with the way that we responded in the fourth quarter."
Although the Warriors committed only 13 turnovers, the Bulldogs limited Culleoka to a modest 15 field goals on 32 percent shooting, which included a 4-of-18 effort from three-point range.
The Warriors did hold a 10-5 edge on the offensive glass, but Cornersville outrebounded Culleoka 26-25 overall.
Despite hitting only 2-of-10 attempts behind the arc and committing 17 turnovers, the Bulldogs shot a respectable 42 percent (13-of-31) from the field while knocking down 20-of-31 free throws, highlighted by a 7-of-8 effort in the fourth quarter by Tate Lowery.
The Warriors, conversely, struggled at the charity stripe and hit just 8-of-18 foul shots overall.
