FORT WORTH, Texas -- R.J. Davis scored a career-high 30 points with a nifty layup while being fouled in overtime, and eighth-seeded North Carolina blew a 25-point second-half lead but still found a way to beat defending champion Baylor 93-86 in the second round of the NCAA tournament Saturday.
Brady Manek had 26 points before getting ejected because of a flagrant foul midway through the second half, right after his 3-pointer had given the Tar Heels (26-9) their largest lead.
A year after going out in the first round of the tourney in retiring coach Roy Williams' final game, Davis, Armando Bacot and these Tar Heels (26-9) are headed to Philadelphia and a Sweet 16 for first-year coach Hubert Davis.
R.J. Davis, who had five 3-pointers in regulation, got his only points in overtime on the off-balance layup with 1:18 left and added the free throw for a 91-85 lead.
All-Atlantic Coast Conference power forward Bacot had 15 points and 16 rebounds for North Carolina. After missing three of four free throws in the final 38 seconds of regulation, he made three of five in overtime.
The Tar Heels won as a No. 8 seed over a top seed for the third time. They did so on the way to the Final Four in 2000, 10 years after beating top-seeded Oklahoma when Davis was a player for Dean Smith.
Baylor lost in the second round for the second time in the last three NCAA tourneys. The Bears, who fell to top-seeded Gonzaga in the round of 32 three years ago, were trying to match the biggest comeback ever in an NCAA tournament game.
"They consistently started to press us, and that bothered us," Hubert Davis said of the Bears' rally. "It sped us up, and made us make uncharacteristic plays. It made us turn the ball over. I also felt at times in pressure situations, we lost our composure. I feel like we helped them. But Baylor's a great team. They're the defending national champions and did not want to go home. They stepped up their effort, but we stepped up our effort as well."
Manek, the graduate transfer from Oklahoma of the Big 12 who had 28 points in the NCAA opener Thursday, was ejected with 10:08 left after his left elbow to the face of Sochan as they were battling underneath the Baylor basket. Manek had just drained a 3-pointer that put the Tar Heels ahead 67-42.
With Manek out, and Caleb Love fouling out soon after that, the Tar Heels had 10 turnovers as Baylor turned up the pressure and made a furious rally.
The Bears got within 76-73 on a three-point play with 1:48 left by Akinjo, who had another one with 16 seconds left to tie the game at 80-80. North Carolina had one more shot, but Davis' 3-point try hit off the front of the rim.
"Never underestimate the heart of a champion," Baylor coach Scott Drew said. "I think our guys really displayed that. I'm really proud of their effort ... just how they carried themselves all year long."
Baylor scored 11 straight points in less than two minutes after Manek's ejection. Sochan made the second free throw before having an assist on a layup by Flagler, who then had consecutive 3s off UNC turnovers. The Bears moved within 67-53 when Akinjo hit two free throws after Bacot was called for a technical foul as the two tumbled to the floor.
Things became testy midway through the first half, and Sochan got a technical foul when he appeared to lock his legs together and almost pull Bacot to the floor with him. Love made both free throws, Manek drilled a 3-pointer off an inbound pass and Davis then added a breakaway 3 off a turnover for a 24-10 lead.
North Carolina will play either UCLA or Saint Mary's in the Sweet 16.
