PROVIDENCE, R.I. --- Scottie Reynolds was benched, his shot wasn't falling and No. 2 seed Villanova was on the brink of having its NCAA Tournament run end in the biggest of upsets.
He responded with a clutch performance at the foul line in the final minutes of regulation, and the Wildcats survived a scare from Robert Morris in a 73-70 overtime victory Thursday.
"I always think we're going to win; I always think we're going to find a way," coach Jay Wright said.
Trailing 55-47 with 4:19 left in the secon half, Reynolds attacked the basket and led a fearless rally from the free-throw line. His reliable stroke was absent, but he never stopped hustling in the second half, and Reynolds' sliding save of a loose ball at Robert Morris' end led to two free throws that cut the lead to 55-51.
The Colonials (23-12) coughed up the ball again. Reynolds was fouled again. And he delivered again on both attempts from the line and it was 55-53 with 2:10 left.
Robert Morris committed its 21st turnover and fouled Reynolds. Two more from the line and it was tied at 55 with 1:48 left in regulation.
All those missed jumpers -- Reynolds was 2 of 15 from the floor -- seemed forgotten for the Wildcats (25-7) .
"He is a live-by-the-sword, die-by-the-sword kind of guy," Wright said. "And I'll die by his sword any time because we've won so many. Even when he was missing them, I was saying, 'If that's how we're going to go down, I'll go down with him any time.' "
The Wildcats didn't going down.
