Three-time NASCAR champion Darrell Waltrip heads the latest class of inductees into the International Motorsports Hall of Fame.

Waltrip is joined by longtime drag racing stars Joe Amato and Bob Glidden, powerboat champion Chip Hanauer and Formula One and CART champion Nigel Mansell.

Waltrip won Winston Cup titles in 1981, 1982 and 1985, driving for Junior Johnson. He also had 84 wins -- tied for third all-time with former inductee Bobby Allison -- and 54 poles, and was named driver of the year three times. . . .

Kevin Harvick and Kasey Kahne were put on probation through the end of NASCAR's season and fined $10,000 each for deliberately crashing into each other after a race at Phoenix International Raceway.

* COLLEGE BASKETBALL: Shane Clark, a 6-foot-7 small forward from Hargrave Military Academy (Va.), signed a national letter-of-intent to play at Maryland next season. Clark is rated the nation's fourth-best prep school player, according to the Hoop Scoop recruiting service.

Clark, who averaged 16 points, 9 rebounds and 5 blocks as a junior at Cardinal Doughtery High in Philadelphia, had orally committed to Villanova last year. Maryland might not sign additional players for next season because the Terps are expected to return all significant players for the 2005-06 season and because the high school class of 2005 is considered weaker than past years. . . .

In the second game of an exhibition doubleheader at Smith Center, six players scored in double figures to lead George Washington to a 106-45 win over Division III Randolph-Macon. Sophomore guards J.R. Pinnock and Carl Elliott led the Colonials with 17 and 16 points, respectively. In the first game, senior Jessica Simmonds scored 22 points and senior Anna Montanana had 14 points, 12 rebounds and 9 assists as GW beat UMMC Ekaterinburg, a Russian club team, 70-55.

* COLLEGE FOOTBALL: Stefan LeFors threw three touchdown passes and No. 12 Louisville (7-1, 5-0 Conference USA) rolled to a 55-28 victory over TCU (4-5, 2-4). . . .

Two Michigan State players were arrested and charged with possessing a dangerous chemical compound after they allegedly planted homemade bombs that blew up outside campus apartments.

Terry Love and Irving Campbell, both 19-year-old redshirt freshman wide receivers, were arrested Tuesday morning as they left the scene of the first explosion, campus police said. A second bomb exploded shortly afterward, and a third was detonated by the campus police bomb squad.

The men said they planted the bombs in Spartan Village as a prank, campus police Sgt. Florene McGlothian-Taylor said. No one was hurt and there was no property damage, McGlothian-Taylor said. The players were released on $500 bond after being arraigned Tuesday.

* TENNIS: U.S. Open champion Svetlana Kuznetsova avoided a second-set collapse and Serena Williams had to rally to win their matches at the WTA Championships in Los Angeles.

Kuznetsova held on to defeat Russian countrywoman Vera Zvonareva, 6-2, 6-4, after she blew most of a 5-1 lead in the second set when there were seven service breaks. Williams fought past Anastasia Myskina, 4-6, 6-3, 6-4, in the $3 million round-robin tournament.
