Boyle County's girls led visiting South Laurel through 70 minutes of Tuesday's game, but couldn't hold on as the Cardinals scored twice in the final 10 minutes for a 2-1 win.
"This was a very disappointing loss for the Rebels," Boyle coach Brian Deem said.
The Rebels (3-4-2) led 1-0 after a second half-goal by Sarah Hall, but South Laurel (4-4) got the equalizer with 10 minutes to play. The Cardinals then got the game-winner with two minutes to go.
Boyle held a 12-6 advantage in shots on goal.
"It was a very well-played game by both teams," Deem said. "We did our jobs, made adjustments at halftime, got us our goal and absolutely were shutting down any type of offense that South Laurel was trying to generate.
"Then with 10 to go, it appeared that we just said, 'OK.' We just didn't play 80 minutes of soccer. Again, until they make a decision to play 80 minutes of soccer at the top of their level, there will be more heartbreaking losses like this to come."
