CHARLOTTE, N.C. (Interstat) — In a frantic, back-and-forth Atlantic Coast Conference tournament quarterfinal that saw a 17-point lead evaporate and a last-second comeback attempt fall just short, the Clemson Tigers edged the North Carolina Tar Heels 80-79 on Thursday night at Spectrum Center.

The victory, witnessed by a crowd of 17,627, avenged a regular-season loss to the Tar Heels just over a week prior and propelled Clemson to a 24-9 record. North Carolina fell to 24-8.

The game’s defining sequence was a chaotic final 12 seconds that encapsulated the entire second-half drama. Trailing 79-76 after North Carolina’s Derek Dixon sank a 3-pointer, Clemson’s Dillon Hunter was fouled on the ensuing inbounds play with 11 seconds remaining. The sophomore guard calmly sank both free throws to cut the deficit to one.

North Carolina’s Seth Trimble then inbounded the ball to Dixon, who was immediately fouled by Clemson’s Nick Davidson with only two seconds on the clock. Dixon, however, missed the front end of the one-and-one opportunity. Davidson secured the rebound for Clemson and was fouled by Dixon, sending the Clemson forward to the line for two shots with a chance to win the game with 2.2 seconds left.

Davidson, who finished with a team-high 17 points, missed the first free throw. After a Clemson timeout, his second attempt also rimmed out. North Carolina’s Jarin Stevenson grabbed the defensive rebound, but the Tar Heels had no timeouts remaining. Stevenson’s desperate full-court heave as time expired was not close, sealing the heart-stopping one-point victory for Clemson.

The game’s narrative was one of two starkly different halves. Clemson dominated the opening period, building a 39-31 lead at intermission and extending it to 17 points early in the second half behind efficient offense and disruptive defense. North Carolina star Henri Veesaar, a 7-foot center from Estonia, was held in check early but erupted after halftime to fuel the comeback. Veesaar finished with a game-high 28 points to go along with two blocks, relentlessly attacking the interior as the Tar Heels chipped away at the large deficit.

Clemson’s balance ultimately countered Veesaar’s brilliance. Alongside Davidson’s 17, the Tigers got 14 points from Dillon Hunter, 13 from RJ Godfrey, 11 from Ace Buckner and 10 from Jestin Porter. Their ability to generate offense from multiple sources proved critical when North Carolina made its run.

North Carolina’s second-half surge was engineered by Veesaar and a sharp backcourt. Derek Dixon scored 16 of his 16 points after halftime, including four 3-pointers in the final minutes that kept the Tar Heels within striking distance. Seth Trimble facilitated the offense masterfully, dishing out eight assists to go with 13 points.

The Tar Heels finally drew even and then took their first lead since the game’s opening minutes on a Veesaar 3-pointer that made it 71-68 with just over a minute to play. The teams then traded blows in a tense final minute, setting the stage for the dramatic, foul-filled conclusion at the free-throw line.

Clemson’s victory, which went against a pregame statistical projection favoring North Carolina, also surpassed the betting over/under total of 140.5 points. The Tigers advance to face Duke in the semifinal round on Friday. North Carolina, once in control of its postseason destiny, now awaits its fate on Selection Sunday.
