With four fouls to his name early in the fourth quarter of Saturday's quarterfinal game against Campbell, Prospect Mountain guard Pat Cassidy threw his hands to his head when he heard a whistle.

Cassidy couldn't believe it. He was playing so conservatively on defense. He didn't want to sit on the bench for the biggest game of his career.

But that's where he started walking. Until coach told him to turn it around.

"My heart dropped. I felt so bad," Cassidy said of the foul call. "Then when my coach told me it wasn’t me. I was like, 'Oh okay.'"

Instead, it was teammate Ethan Henderson who had his No. 10 flashed on the scoreboard. Henderson went to the bench and Cassidy stayed in the game. Cassidy never did commit a fifth and decisive foul. He hit two big 3-pointers in the fourth to help lift the T'wolves to the win.

Campbell coach Patrick Roye said if Cassidy had fouled out Campbell might have won the game. Cassidy is Prospect's primary ball handler and the Cougars were already creating a lot of pressure defensively. With Cassidy out, Zach Drouin and Henderson would be forced to handle the ball.

But Cassidy survived and Prospect did, too.

Prospect plays No. 2 Conant in the D-III semifinals Tuesday night at Southern New Hampshire University. Tipoff is scheduled for 5:30 p.m.
