LOUISVILLE, Ky. -- The beards are safe. Not so the noses.

The No. 11 Louisville Cardinals, playing their third game since taking a vow not to shave until they lose, got 19 points from senior All-American guard Russ Smith and beat South Florida 80-54 in a sloppy game on Tuesday night at the KFC Yum! Center.

The noses? Senior forward Luke Hancock, who had 16 points, suffered a bloody nose on the first play of the game when he was clouted on a drive to the basket.

"We didn't play well," Louisville coach Rick Pitino said. "Lets face it, we're better than them. We didn't shoot well. The same shots we hit the other night didn't go in tonight. (Louisville was 3-of-18 on 3-point shots). But we did some things well. We moved the ball. We had 10 steals. I like the way we played."

Having beaten South Florida (12-15, 3-11 American Athletic Conference) by 39 points in Florida 26 days ago, Louisville (22-4, 11-2) looked sloppy at times, letting USF cut a 30-14 lead to 30-21 late in the first half before regrouping. The Cardinals led 46-28 at halftime.

Evidence of Louisville's lackadaisical play was South Florida hitting 10 of its first 15 shots from the field.

"That's a really good basketball team. I don't think we played poorly, I just think they're really good," South Florida coach Stan Heath said. "A lot of things we did a lot better this game than we did the last time we played them. They come at you in so many different ways, it's just really hard to get a rhythm going.

The Bulls then opened the second half with a 6-0 run as Louisville sophomore forward Montrezl Harrell picked up his third and fourth fouls 30 seconds into the half. The third foul came when he inadvertently ran into a USF player while coming down the court. When he threw up his hands, a technical was called, giving him four fouls.

Coach Rick Pitino promptly yanked him in favor of junior Wayne Blackshear, who proceeded to pick up his third and fourth fouls within a minute. He was replaced by freshman forward Akou Agau, and Pitino delivered a few choice words to his team during a subsequent timeout.

Whatever he said had an effect because the Cards went on a 29-13 run to lead 75-47.

"It was a shame Montrezl got into foul trouble," Pitino said. "He was having a good game (12 points in the first half)."

Senior forward Victor Rudd led South Florida with 27 points. He was the only USF player in double figures.

The Bulls made 11-of-19 shots from the field in the first half (58 percent) and finished 22-of-45 (48.9 percent). Louisville made 34-of-71 (47.9 percent).

"Offensively, we were pretty good but didn't shoot from the 3 very well," Heath said. "But I'll take 48 percent shooting at Louisville. They really just beat us at a game of possessions. They get 71 shots we get 45. How do they do it? ... It wasn't that we were turning it over on the press in the backcourt. We really kind of got into the half-court and had some mistakes."

The Cardinals had a 36-30 edge in rebounding and 10 steals to the Bulls' two.

"I'm not going to be happy that we lost," Heath said. "But we aren't going to beat ourselves up and we are going to get back to Tampa in 80 degree weather and enjoy ourselves."

Louisville senior center Stephan Van Treese had eight rebounds and junior point guard Chris Jones added three steals.

Harrell finished with 14 points and had three dunks, setting a school season record with 62.

"It's pretty amazing a sophomore sets that record after playing limited minutes as a freshman," Pitino said. "I would have thought that Dr. Dunkenstein (Darrell Griffith, star of the 1980 national title team) would have set that record by a mile."

Louisville freshman reserve guard Terry Rozier had 13 points, his second double-figure game in a row.

Pitino expressed happiness with the way the Cardinals, who won their fifth game in a row, are improving.

"I like the way we're playing basketball," he said. "Low turnovers, high assists. Our defense is getting better. We're playing the way you have to play to win in March."
