Guard Othell Wilson, whose foul allowed Clemson to take the game into overtime, redeemed himself with a basket with two seconds left in the extra period as third-ranked visiting Virginia escaped with an 85-83 Atlantic Coast Conference victory last night.

Virginia (22-3, 9-2) leads the ACC, Clemson (9-18, 1-11) is in the cellar.

The score was tied at 81 when the Cavaliers' Rick Carlisle was fouled with two seconds left in regulation. Carlisle made two free throws that apparently ensured victory. But Wilson fouled Anthony Jenkins, and the freshman sank the one-and-one to send the contest into overtime.

Clemson missed two shots in the next minute before the Cavaliers went into their deliberate offense, running more than three minutes off the clock before Wilson drove in for the winning shot.

The Cavaliers trailed by as many as nine points in the second half, with Clemson holding a 54-45 advantage with 14:13 remaining. But Virginia, sparked by center Ralph Sampson and Wilson, rallied, scoring 13 of the next 17 points to tie at 58 with 10:11 left.

The Tigers countered to take a 74-66 lead behind Mark Campbell, who scored 26 points and made seven of seven three-point shots.

Virginia rallied again as Sampson made a stuff, and the Cavaliers again scored 13 of the next 17 points for an 81-78 lead with 2 1/2 minutes left.
