Junior Isabella Cassoni scored a game-high 21 points as the Spartans (16-7) won their fifth straight game.
“We pulled it out,” Cassoni said. “We had a rough first half, but we kept pushing and we pulled out the win.”
The Warriors led 7-6 after the first quarter. They went on a 10-2 run in the second quarter, capped by a 3-pointer by Ally Frye to give Mariemont a 17-8 lead at the half.
In the second half, the Spartans turned up the pressure defensively, capping a 15-3 run on a steal and layup by Cassoni to take a 23-20 lead with less than six minutes remaining.
“We kind of had a rough shooting day, but I knew I had to step up and be a leader,” Cassoni said.
Cassoni scored 11 points in the fourth quarter, making 4-of-5 free throws.
“Her quickness and ball handling are so good,” Gabbard said. “Sometimes she’s too quick. She had a great game scoring-wise, thank goodness, because no one else was hitting. I think I looked up there once and she had 20 and we had 26.”
Mariemont cut the lead to 32-29 on a 3-pointer by sophomore Kendall Spreen with less than a minute remaining. The Spartans turned the ball over on their next possession, but the Warriors weren’t able to capitalize. Waynesville senior Leah Butterbaugh hit a free throw down the stretch to seal the victory.
Waynesville advanced to play Worthington Christian at 5:30 p.m. Wednesday in a D-III regional semifinal game at Springfield. Gabbard doesn’t know much about his team’s next opponent, but that’s typical for this time of year, he said.
“We don’t look ahead,” Gabbard said. “We try not to do that, we’re a little superstitious. Obviously, they’re good.”
Waynesville is back in the regional semifinals after falling to Purcell Marian in the district finals last winter.
“We’ve worked very hard for it,” Cassoni said. “Every girl showed up every day and pushed themselves. We’ve gotten a lot better and we’re ready to keep going. I feel like we’ve worked our butts off and we’re ready for the next one.”
