Kinder defeated Rosepine twice in the regular season, but the Lady Eagles got theirs on the biggest stage.
Behind a gem in the circle from Chloe Bennett, Rosepine beat Kinder 8-1 to advance to the Class 2A State Semifinals.
"It's a great feeling," Rosepine head coach Glenn Granger said. "We still have two games left, but to be honest with you, going into this season, that was the team to beat. To win state, Kinder was the team to beat. Even though Mangham is the returning state champ, they are the real deal.
"We stressed all week: no fear, no errors and let's go at them."
Bennett struck out four, walked one batter and gave up six hits over seven innings to the No. 2 ranked team in the state.
After two scoreless innings, the Rosepine offense got a boost with a two-run home run from Haylee Brinlee to go up 2-0.
Later in the inning, Cheyenne Vander hit a triple off the wall to drive in Desiree Squires, and Peyton Thaler hit a triple of her own to score Vander.
"It's great, because a pitcher like (Kinder's Sarah Gartman), she's good, and if we can fire up the bats against her, then we are unstoppable," Brinlee said.
In the top of the fifth inning, Kelsey Gill opened up the inning with a solo shot to make it 5-0.
"We made our adjustments really early," Gill said. "That really helped a lot.
"I just backed off the plate a little bit, and quick hands are the key to faster pitchers."
In the bottom of the inning, Kinder threatened with runners on third and second with no outs, but Bennet got a pop up and back-to-back strikeouts to get out of the jam.
"We've tried to stress all year long that when you have the momentum, put it to them," Granger said. "It worked today."
In the top of the seventh, the Lady Eagles scored three runs to put the game out of reach, as Collins closed the door in the seventh despite dealing with cramps in her leg for the latter half the contest.
"She came through for us," Gill said. "She was drinking pickle juice and eating mustard. She came through."
Thayler went 3-for-4, and Bennet went 2-for-4 at the plate.
Rosepine will play No. 3 Doyle at 11:30 a.m. Saturday for a shot to play in the state championship game.
"We don't know anything about Doyle, and they don't know anything about us," Granger said. "I could call Rapides tonight, and he can give me a scouting report. You can have the best scouting report there is, but you just have to come play. That's the bottom line."
