Clemson led Florida State by as many as 18 points in the second half before falling to the Seminoles 81-79 Wednesday night in Tallahassee.
The 11th-ranked Tigers (20-5, 9-4) were unable to overcome 21 turnovers and had their four-game winning streak snapped.
Clemson had multiple chances to tie the game in overtime after the Seminoles (18-8, 7-7) took the lead, but David Skara made only 1-of-2 free throws with the Tigers trailing by two with five seconds remaining.
Moments later, with Clemson down by three, Marcquise Reed was fouled and made the first free throw before missing the second on purpose. Elijah Thomas grabbed the rebound but was unable to convert under the basket.
