CLEMSON, S.C. -- As a self-described basketball junkie who frequently talks about how many games he watches, Dave Leitao admits that his memory often fails him when he's asked to provide details.

That probably won't be the case with visiting Virginia's 64-63 triumph Sunday over 19th-ranked Clemson.

"I told our guys, 'I'm not sure if I've ever seen a game like this before,' " Leitao said.

The Cavaliers, who had gone more than a year between road victories, scored the last 15 points Sunday to steal their second road win of the week.

Jason Cain's tip-in with 17 seconds lifted UVa (13-6, 5-2 ACC) past the Tigers, whose last points came on a pair of Trevor Booker free throws that made it 63-49 with 5:05 remaining.

Clemson (18-4, 4-4) had led by as much as 61-45 on a Cliff Hammonds 3-pointer with 8:47 left.

"I told them when got to a timeout at 52-41, 'We're down by 11, but it seems like 40,' " said Leitao, whose Cavaliers were the victims of a 90-64 drubbing here last year.

"It didn't look like we had the kind of energy it was going to take to come back and win the ballgame."

Moments after the timeout, All-ACC point guard Sean Singletary picked up two charging fouls in the span of 26 seconds, giving him four personals and sending him to the bench with 11:36 left.

Singletary did not contribute a basket to the game-ending 15-0 run, but it was his rebound of Mamadi Diane's missed 3-pointer that allowed Virginia to keep possession with 20 seconds left.

"You know me," said Singletary, a 6-foot junior. "I think I can jump higher than anybody out there."

As he was crashing to the floor, Singletary passed to Adrian Joseph, who failed to convert on a drive from the right corner, only to have Cain get the game-winning tip. It was Cain's only field goal of the game.

"Everybody ran past me to get to Adrian," Cain said. "I was almost by myself."

Clemson's Vernon Hamilton took the ensuing inbounds pass and sped down the floor, but his contested one-hander went over the basket and was controlled by Diane.

"Very gratifying," Cain called the win. "I can't remember the last time we've won back-to-back road games."

In the careers of their two seniors, Cain and J.R. Reynolds, the Cavaliers had never won more than one ACC road game in any season. That was before Virginia won 71-58 Wednesday at North Carolina State and then stunned the Tigers.

It was just one more memory for Reynolds, who had scored 40 and 29 points in his previous two games. He led all scorers Sunday with 18 points, making eight of 12 shots from the field.

Reynolds had five points during the 15-0 run, when the Cavaliers were led by Joseph, who scored eight of his 11 points in the final 3:59.

"Of all the guys that sometimes can get distracted by the surroundings, Adrian, by his personality, never does," Leitao said. "At times, you'd want him to be a little bit more charged and he really isn't. At times, when you think he'd get bothered, he really isn't.

"He just kind of lives in that box mentally. The fact that he made a big '3' on the road last year at [Virginia] Tech speaks to a mindset."

Apparently, it also didn't bother Joseph that he had gone scoreless Wednesday at N.C. State and had seen his scoring average drop from 10.1 to 7.5 since mid-December.

It was the second straight bitter loss for Clemson, still reeling from a 68-66 loss at Duke on Thursday night, when the Blue Devils scored at the buzzer after time was added to the clock -- incorrectly, according to the ACC office.

"We have to get it back together," Clemson coach Oliver Purnell said. "We're fortuntate to have a week off to do so. I think we came out flat in the first half but picked it up in the second half. Playing one of the most explosive teams in the ACC caught up with us."

For all of its heroics, Virginia needed some help from the Tigers, who entered the game with the ACC's lowest free-throw percentage (58.9).

Clemson was 9-for-13 from the line before James Mays missed two free throws with the Tigers leading 63-55 with 2:28 left. Then, after a jumper by Reynolds, Hamilton missed the front end of a one-and-one with 1:55 remaining.

Reynolds tried to console his one-time Virginia private-school rival and friend after the game.

"He broke my heart last year," said Reynolds, who had not previously played on a losing team in his battles with Hamilton. "Once was one too many."
