Coming off last week's 10-run loss to Greenbrier, Lakeside got its revenge on Thursday.
The Lady Panthers scored all of their runs in the third inning to defeat the Lady Wolfpack 4-2.
"It's a funny thing," Lakeside coach Jay Matthews said. "Anybody can beat anybody on any given day."
Lakeside pounded out 10 hits on its home field, but trailed after the first two innings.
Greenbrier held a 1-0 lead when Kellie Tiller slapped a two-out RBI single to center in the third to expand the Lady Wolfpack advantage to 2-0.
Christie Tolbert cut the lead in half in the bottom of the inning with an RBI double. Two batters later, Tiffany Pate tied it with an infield groundout.
Later in the inning, Krystle Miller reached on an infield single. Colleen Markyna followed with a two-run triple to left to put the Lady Panthers up for good at 4-2.
"We didn't call out the troops," Matthews said. "We just got some practice in and played a good game."
Ashlee Pate limited Greenbrier to three hits in the final four innings to close the door on the Lady Wolfpack's comeback bid.
"Give Lakeside credit," Greenbrier coach Garrett Black said. "They did what we did last week. We took advantage of a couple of mistakes (last week) and they were able to capitalize."
Each team will finish its regular season next week and look to advance to the region tournament in two weeks. The top two region teams will advance to the state sectionals.
"We can't look past anyone," Black said. "We've got a job to do next week and we've got to make sure we put ourselves in a position to be in the (region) playoffs and hopefully open up as the number one seed."
