Houston's fans chanted "Sweet 16" in the final minute of the Cougars' NCAA tournament win over Ohio State.

The celebration was long overdue — it's been 35 years since the Cougars have made this trip.

"I saw a lot of proud Cougars up there behind us tonight," Houston coach Kelvin Sampson said, "and the ones I was happiest for were the guys that's been supporting this program since those days."

Corey Davis scored 21 points to help Houston beat the Buckeyes 74-59 in a second-round Midwest Regional game Sunday night. It marked the Cougars' 33rd win of the season — breaking the school's season record set by the 1983-84 team. That was the last Houston squad to reach the Sweet 16.

The win was especially significant for Robinson, a senior who has played in a school-record 135 games. He watched teams celebrate reaching the Sweet 16 on social media Saturday night and wanted his own moment. He scored 13 points to help make it happen.

"When I went to bed last night, all I was thinking about was winning just so we can do that, so I can see how it feels," he said. "It was exactly — to be going to the Sweet 16, it feels amazing."

Houston (33-3) advanced to face Kentucky. C.J. Jackson scored 18 points, and Kaleb Wesson added 15 for Ohio State (20-15).

The Buckeyes finished 8-12 in Big Ten play and were seeded eighth in the conference tournament, so getting this far was an accomplishment.

"I told them in the locker room, I don't know if I've ever been a part of a team where we've faced as many challenges and had come through on the other end in such a positive way," Ohio State coach Chris Holtmann said. "It just really speaks to the quality of our players and the quality of people that they are."

North Carolina 81, Washington 59: Luke Maye and Nassir Little each scored 20 points and top-seeded North Carolina breezed past Washington. The Tar Heels (29-6) never trailed and moved on to face fifth-seeded Auburn on Friday in a Midwest Regional semifinal. Maye added 14 rebounds for North Carolina. The Tar Heels committed 10 turnovers in the first half and led by eight points at the break. But they bolted out in the second half, put together a 13-0 run over five minutes and pulled away.

Pac-12 player of the year Jaylen Nowell paced Washington (28-8) with 12 points.
