Madison Southern 81, Harrodsburg 55 - At Berea, Southern (15-12) pulled away in the second half to spoil the season finale for Harrodsburg (10-15).
Southern led early and fortified its lead with strong shooting that included 11 3-point goals.

The Pioneers cut Southern's lead to eight points midway through the third quarter but got no closer, in part due to foul trouble.

Danville was within 51-47 after three quarters, but Russell pulled away at the start of the fourth quarter for its seventh straight win.
"I thought we played really well in the first three quarters, but Russell scored the first couple of baskets in the fourth quarter and got it to double digits right away, and we weren't able to cut the lead down," Danville coach Justin Schommer said. "We missed a lot of open shots."
Krystal Jackson scored a game-high 24 points for Danville, but no other Lady Admiral reached double figures.
Meanwhile, Schommer said Danville had trouble with Russell's offensive 1-2 punch of Amy Ellis and Kendra Robertson, who scored 23 and 16 points, respectively.
"Russell County shot the ball really well, and we had a hard time stopping Ellis and Robertson," he said. "But it was a good game for us before districts to play a good opponent like Russell County."
Danville lost despite forcing 20 turnovers and committing only 12.
