Russ Smith's 25 points led Louisville (16-2, 4-1), which had its 11-game winning streak stopped.
Trailing 48-40 4 minutes into the second half, Syracuse's 12-4 run tied it with 10 minutes remaining. Triche and Carter-Williams combined to score 12 straight points in a 16-10 spurt for a 66-62 lead with 4:37 left.

No. 13 Butler 64, No. 8 Gonzaga 63 • Roosevelt Jones stole an inbound pass with 3.5 seconds left and hit a floater from just inside the foul line right before the buzzer to help Butler upset Gonzaga.
Jones finished with 20 points and the Bulldogs have now won 13 in a row including two straight without their top scorer, Rotnei Clarke. It's the first time Butler (16-2, 3-0 Atlantic 10) has ever beaten three top 10 teams in one season. They also defeated No. 9 North Carolina in November and No. 1 Indiana in December.
Gonzaga (17-2, 4-0 West Coast Conference) was led by Saw Dower and Elias Harris who each had 20 points. The loss ended the Zags eight-game winning streak.
The game was considered the biggest non-power conference matchup of the season, and it met the hype.
Trailing 33-32 at the half, Butler scored the first five points of the second half and never trailed again until Elias Harris scored with 1:24 to go the teams traded leads on the next four possessions before Jones won it.
No. 10 Florida 83, No. 17 Missouri 52 • Scottie Wilbekin had 13 points and 10 assists, his first career double-double as Florida thumped Missouri.
The victory was coach Billy Donovan's 400th with the Gators, making him the third coach in Southeastern Conference history to accomplish that feat with the same school. He joined Kentucky's Adolph Rupp and LSU's Dale Brown in the 400-win club.
Florida, which won its sixth consecutive game, also made a statement about being the class of the Southeastern Conference.
And the Gators aren't even fully healthy.
Erik Murphy scored 15 points despite playing with a broken finger, and Kenny Boynton added 14.
Wilbekin did a strong defensive job on Missouri point guard Phil Pressey, who finished with two points on 1-of-7 shooting with 10 turnovers and six assists.
Jabari Brown led the Tigers (13-4, 2-2) with 16 points.
