Los Angeles ? Kevin O’Neill returned to the college ranks Saturday when he was announced as Southern California’s basketball coach, taking over from Tim Floyd.

The school announced O’Neill’s hiring in an e-mail. Floyd suddenly resigned June 9 amid allegations that he paid to have O.J. Mayo delivered to the Trojans. He said he was quitting after four seasons because he no longer had enthusiasm for his job.

O’Neill is scheduled to be introduced Monday at a campus news conference.

“We’re thrilled to have Kevin O’Neill as our men’s basketball coach,” athletic director Mike Garrett said in a statement.

O’Neill’s NBA tenure seemingly appealed to Garrett as well.

“His 30 years of experience at the college and professional levels has prepared him well for this opportunity,” Garrett said.

The 52-year-old defense-oriented coach was an assistant with the NBA’s Memphis Grizzlies this past season. Mayo plays for the Grizzlies. O’Neill led the Toronto Raptors to a 33-49 record in 2004.

O’Neill also had stints with the New York Knicks, Detroit and Indiana.

He returns to the Pac-10 after serving as interim coach at Arizona in 2008 when Lute Olson took a leave of absence.

During his tenure in Tucson, O’Neill led the Wildcats to a 19-15 record and the school’s 24th consecutive NCAA tournament appearance, the nation’s longest active streak.

He was designated Olson’s permanent successor, but when the Hall of Famer returned that spring he announced O’Neill no longer be would part of the program.

O’Neill is 171-180 in 12 seasons as a college head coach, including stints at Marquette, Tennessee and Northwestern.

O’Neill takes charge of a USC program that won at least 20 games and made the NCAA Tournament each of the last three seasons, both school records, at a university best known for its powerhouse football program, which also is being investigated by the NCAA.

Since the Trojans’ season ended in March, starters DeMar DeRozan, Taj Gibson and Daniel Hackett, along with Marcus Johnson, declared for Thursday’s NBA Draft, and the Trojans have lost eight recruits.

BOXING

Klitschko stops Chagaev

Gelsenkirchen, Germany — Wladimir Klitschko again showed his dominance of the heavyweight division, stopping Ruslan Chagaev in a hastily put-together title fight Saturday night before 61,000 fans at a German soccer stadium.

The IBF and WBO champion added the Ring Magazine belt to his haul, knocking Chagaev down in the second round and opening a cut over the Uzbekistan-born fighter’s left eye in the eighth.

Referee Eddie Cotton stopped the fight before the 10th round.

Chagaev, who is the WBA’s “champion in recess,” did little more than raise a deep bruise under Klitschko’s right eye.

The sellout crowd was the biggest boxing audience in Germany since Max Schmeling knocked out Adolf Heuser in front of 70,000 people in Stuttgart in 1939.

Phelps is using the Montreal meet as a final tuneup for the U.S. championships, which will serve as the trials for the world championships in Rome next month.

West Allis, Wis. — Carl Edwards made the most of his one-day Wisconsin getaway, winning Saturday’s Nationwide series race at the Milwaukee Mile after taking a brief break from his Sprint Cup duties in California.

It’s a repeat win at Milwaukee and the first Nationwide win of this season for Edwards, who took the lead from fellow Cup commuter Kyle Busch with 44 laps left in the race and wasn’t significantly challenged the rest of the way. Edwards, who did his customary backflip on the frontstretch after winning Saturday, also won last year’s race at the Mile.

Busch finished second, followed by Brad Keselowski.
