LOS ANGELES (AP) — Jio Fontan of USC had to battle one of the better point guards in the country using one hand.

Fontan injured his left hand in the second half and said "it was hard for me to dribble." But that didn't stop Fontan from shutting down Dayton's Kevin Dillard.

Fontan also made key baskets, Eric Wise scored a season-high 19 points and Aaron Fuller added 12 as Southern California defeated Dayton 63-61 in overtime Sunday night.

Fuller scored the go-ahead points on free throws and put back a miss for a 59-55 lead. Fontan completed a three-point play on a spin move near the free throw line to make it 62-58, and the Trojans (5-8) held on for their second win in nine games.

The Flyers (9-4) had the last shot, but Dillard's running 3-pointer was wide left. Dillard led Dayton with 13 points, and Devin Oliver had 11 points, 12 rebounds.

Dillard, Dayton's leading scorer who is on the watch list for the Bob Cousy Award for point guards, was held to 1 of 10 from the field but made 11 of 12 free throw attempts.

USC head coach Kevin O' Neill said Fontan did an "unbelievable job" against Dillard in a win USC badly needed before it opens Pac-12 play.

"It's a heck of a win," O'Neill said. "They're a good team. I'm not taking anything away from Dayton, but our immaturity staggers me sometimes. I think Kevin Dillard is a great player, someone who is going to play on the next level, and I think that Jio did a great job on him on both ends of the court."

Fontan, a Fordham transfer who briefly played in the Atlantic 10, said he looked forward to the matchup against Dillard.

"I got a lot of respect for him," Fontan said. "We were in the same class in high school. I heard a lot about him coming up. I know he's a very, very good point guard. I consider myself a pretty good point guard as well. When you've got two leaders of the team on the court that are being spoken about, you kind of go at it. It was a war. It was one of the most physical battles we had, I think for both of us, this year. "

Wise was ejected after he received two technical fouls at 5:29 of the second half for apparent comments that officials heard.

"Vulgar language," Fontan said, adding that "it wasn't directed at anybody."

USC took a 53-51 lead with about 6 seconds left in the second half when Fontan scored. Dayton came out of a timeout, and Dillard fed Oliver for a layup as time expired on a play that was reviewed and upheld.

Both teams had chances to break a 51-51 tie, but USC's J.T. Terrell missed two free throws, and Dillard missed a 3-point attempt that was rebounded by USC with 33.4 seconds remaining.

Dayton pulled to within one point three times in the second half before Oliver tied it at 51 on Dayton's first 3-pointer of the game with 2:43 left. The Flyers had gone 0 for 9 and were in danger of having their 129-game streak of at least one 3-pointer made snapped. The Flyers shot 34.5 percent from the field for the game.

"We just had to play perfect because our offense wasn't getting it done tonight, which is the kicker," Dayton head coach Archie Miller said. "You can't shoot like that on the road and have 17 turnovers, no matter what."

Wise made two free throws for a 37-27 lead early in the second half before Dayton began to chip away.

USC led 27-20 at halftime. The Flyers shot only 31 percent in the first half and committed 10 turnovers against a Trojans team that features two 7-footers.

"They blocked seven shots, saved a few bunnies around the basket," Miller said. "That's the difference when you're playing against a team with that kind of size.""

Miller said Dayton his team often missed open players.

"It will be interesting to see when we watch the film how many times on penetration we missed the open man," he said. "Simple plays, ABC plays we didn't make."
