Catholic's defensive pressure forced Buffalo into 30 turnovers, which prevented the Bison from finding any rhythm offensively.
"They're super athletic and quick," Buffalo coach Jamie Ball said of the Irish. "Their pressure, they're all up in your face. They came to play. Every night, every time that we play them the defense is there. They play as good of defense as we see all season. They're just up in our face. They take everything away that we try to do."
While Buffalo struggled to find consistency, the Irish failed to stop Parkins in the blocks when the Bison eventually worked the ball inside.
"Chelsey Parkins is an outstanding player," Bogan said. "It doesn't matter what we do. She tips it, tips it, gets the rebound. They made a nice run at us."
Ball said for Parkins, it was a routine night from one of the team's most dependable players.
"She's solid," he said. "She's one of the better players around, she's tough. She comes to play every night. We know what we're getting out of her."
For Catholic, Vida Imani led all scorers with 16 points. Whelan finished with 15 points, seven assists and five steals.
Catholic returns to action to play host to Wheeling Central Catholic 5:30 p.m. today, while Buffalo next plays host to Clay-Battelle 2 p.m. on Saturday.
