TULSA, Okla. -- Baylor finally subdued the upstart USC Trojans.

The third-seeded Bears overcame a four-point deficit late in the second half and ousted 11th-seeded USC 82-78 in second-round NCAA Tournament East Region action Sunday night at the BOK Center.

Guard Manu Lecomte scored eight straight points to take the Bears from a two-point hole to a six-point lead with 3:55 left, and Baylor held on.

"I just had to pick it up," Lecomte said. "I was struggling a little bit in the first half. My teammates and my coaches did a great job. They kept believing in me. They kept me in the game and trusted me with the ball in my hands. So I had to go out there and make plays."

The Bears (27-7) advance to the Sweet 16 to face South Carolina in a regional semifinal on Friday at Madison Square Garden in New York.

Baylor earned its fourth trip to the Sweet 16 since 2010, but the first for the majority of the Bears' roster. Baylor last made it to the second weekend of the NCAA Tournament in 2014 when its lone senior, guard Ishmail Wainright, was a freshman.

"Just the history of (Madison Square Garden), to get a chance to go play there and especially get a win there, that would mean the world to me," Bears junior forward Johnathan Motley said. "I love the game of basketball and you dream of moments like this."

Motley and forward Terry Maston each scored 19 points to lead Baylor. Lecomte scored all 12 of his points in the last five minutes.

USC forward Chimezie Metu scored 28 points to lead the Trojans, forward Bennie Boatwright added 16 and guard Elijah Stewart had 12.

"My teammates were getting me the ball in the right spot and I was just trying to make plays," Metu said. "It came down to getting stops on the other end and we weren't able to do that and we fell short."

USC grabbed its first lead of the second half when Stewart hit a 3-pointer for a 53-52 edge.

On the Trojans' next trip down the floor, Stewart drove baseline for a dunk, was fouled and completed a 3-point play for a four-point edge with 9:48 remaining.

Baylor's situation got worse a couple of minutes later when Motley picked up his fourth foul with 8:16 remaining. Motley fouled Metu going toward the rim and Metu hit two free throws to put the Trojans ahead 60-56.

USC (26-10), which defeated Providence in the First Four on Wednesday and sixth-seeded SMU on Friday, appeared to be on the verge of winning three games to get to the Sweet 16.

But that's when Lecomte took over for Baylor. He hit a 3-pointer, was fouled and completed a 4-point play with 4:40 left to kick start his surge down the stretch.

"(Lecomte is) doing a lot of really good things and today in the last five minutes he did a lot of good things," Baylor coach Scott Drew said.

Baylor stretched out its largest lead of the first half to 10 points when Lual-Acuil threw down a dunk on a pick-and-roll assist from Lecomte with 2:08 to go before halftime.

But USC bounced back to cut that margin in half before the break as forward Chimezie Metu scored five straight points.

Mets completed a 3-point play with 1:30 left in the half and then added a jumper a minute later.

Boatwright paced USC in the first half with eight points and Metu added seven.

McClure led Baylor with 14 points in the first 20 minutes as he hit 4 of 7 from 3-point range.

Baylor dominated the rebounding category, 21-12, in the first half. The Bears had 10 offensive rebounds and scored 18 points in the paint in that period.
