"We should have dominated. We crumbled under the pressure," RSM co-coach Joe Schroeder said. "We had a good second half and had a nice lead on them. We couldn't handle the pressure in the fourth quarter."
With six minutes to go, the Hawks had a nine-point lead, but they lost it on turnovers and a Trinity three.
"They were the first team this year that's zoned us and we had trouble with it," RSM co-coach Nick Staab said.
Lyndsie Schorg, one of RSM's leading scorers, also fouled out with a few minutes to go.
"That really hurt us," Schroeder said. "That being said, Trinity Christian couldn't miss. They shot well."
At the final buzzer, the Tigers had tied it up at 42-42, and the girls went into overtime play.
RSM couldn't muster up the points for the win.
Schroeder said the Hawks' team was flat for the night.
"We weren't aggressive with the ball," he said. "We only went to the free throw line twice all night."
"We kind of played not to lose instead of playing to win," he said.
Leading RSM's scoring were senior Paige Harpenau with 12, sophomore Alexis Bunkers with 11, and senior Miranda Staab with eight.
On rebounds, Staab and Schorg both grabbed five for the night, and Harpenau added four steals.
Thursday's loss drops RSM's record to 3-3 overall. The Hawks match up with Hinton at home tonight (Friday).
