WINSTON-SALEM, N.C. (AP) -- Michael Drum's putback with 3 seconds left lifted last-place Wake Forest to a 67-65 victory over Clemson on Wednesday night and denied the Tigers their 20th win of the season.
Clemson's James Mays made two free throws to tie it 65-65 with 34.9 seconds left. Ishmael Smith was thinking shot as he brought the ball down the floor, but at the last second passed to Kyle Visser, who missed from close range. Drum swooped in for the rebound and banked his shot in.
K.C. Rivers raced down the left side and fired up a last-chance shot from close range, but Visser appeared to deflect it as time expired.
Visser had 21 points to lead Wake Forest (12-13, 3-9 Atlantic Coast Conference), which bounced back from an embarrassing 37-point loss to North Carolina by extending the Tigers' misery at Lawrence Joel Veterans Memorial Coliseum.
Clemson has lost 16 straight games here since winning in their first visit to the building in 1990.
Vernon Hamilton had 21 points and 10 rebounds for the Tigers (19-6, 5-6), who have lost six of eight since opening the season 17-0 and were denied in their attempt to reach 20 wins for the first time since 1999.
During the second half, Clemson led twice by six points before Wake Forest went on a Visser-keyed 8-0 run that was capped when Williams' jumper from the left wing with 2:12 left put the Demon Deacons up 64-62 -- their first lead since the opening moments of the half.
