Walter Dix, a junior at Florida State, was late out of the blocks, then broke away over the final 50 meters to win the 100 on Friday night at the NCAA Division I track and field championships in 9.93, the fastest ever by a U.S.-born collegian.
He barely missed the collegiate mark of 9.92 set by Ato Boldon of UCLA at the 1996 NCAAs. Boldon hails from Trinidad and Tobago.
Trindon Holliday of Louisiana State burst out of the blocks first, but Dix caught him about halfway down the Sacramento State track and pulled away. Holliday was second at 10.06, and Travis Padgett of Clemson third at 10.09.
It was the best mark in the world this year, bettering Asafa Powell's 9.97 in Belgrade, Serbia, on May 29. Dix already had the world's fastest 200 this year at 19.69.
Jacquelyn Johnson of Arizona State took the lead in the next-to-last event and went on to become the first three-time NCAA heptathlon champion in 18 years. Her 149-foot 6-inch javelin throw propelled her from fourth place to first, and she finished with 5,984 overall points.

Bodine, driving a Toyota, edged Skinner by 0.188 of a second for his 11th victory in the series, the first since Bodine made a last-lap pass and beat Skinner by 0.116 of a second -- the closest finish in series history -- last June.

Culpepper says he'll block any trade
Trent Green's first practice with the Miami Dolphins was apparently Daunte Culpepper's finale with the team.
Frustrated by the Dolphins' decision to let him participate only in individual drills, Culpepper walked off the practice field -- accompanied by a member of the team's security staff -- about an hour into the start of a three-day mini-camp and vowed that he'd block any plans to trade him.
"Any team that's interested in my services, just sit tight," Culpepper said. "I'm not going to agree to a trade."
Beckham will play despite ankle injury
David Beckham plans to play for Real Madrid at Zaragoza in today's Spanish league match despite a left ankle injury. The midfielder was hit on the ankle early during England's European Championship qualifying win over Estonia.
Beckham could win his first major trophy with Madrid if it beats Zaragoza -- and FC Barcelona and Sevilla lose -- this weekend. Madrid leads two-time defending champion Barcelona on head-to-head results. Each has 72 points, two more than Sevilla, with two games to play.
Complaint against Thurman dropped

A hearing on the accusations against Thurman had been set for Friday, but it was canceled because of the dismissal. Thurman had not been charged with a crime, but a magistrate had been expected to hear testimony to determine whether charges should be filed.
Tennessee ends series with Connecticut
Connecticut and Tennessee, the top two programs in women's college basketball, are ending their annual series.
Connecticut had signed a contract to extend the annual game through the 2008-09 season, but Tennessee terminated the deal, Connecticut officials said.
Tennessee Athletic Director Joan Cronan confirmed that the school had declined to play the game. Connecticut leads the series, 13-9, although Tennessee won the last three meetings.
HBO, Merchant agree to new contract
After a lengthy and sometimes difficult negotiation, HBO and boxing commentator Larry Merchant have agreed to terms on a new contract. Merchant, whose previous contract expired June 1, will continue to work major fights for HBO, including tonight's Madison Square Garden pay-per-view card headlined by Miguel Cotto against Zab Judah. The new contract is for two years, plus two option years, and calls for Merchant, 76, to work about 60% fewer fights a year for an annual salary believed to be in the $700,000 range.
