That time truly put Anderson, still just a 19-year old freshman, in with the Olympic team contenders.
It was the fifth-fastest time this year by an American man, and the third-best by a collegian. Georgia's Justin Gaymon, who finished third in the NCAA final behind Anderson, earlier this year ran a time of 48.53, the best in the college ranks this year.
Still, there remain significant challenges ahead for Anderson if he is to go to Beijing.
The junior outdoor track and field championships are this weekend in Columbus, Ohio, where Anderson will face off against Johnny Dutch who has clocked a 48.68, a time 1/100ths of a second better than Anderson's personal best. The event is not scheduled to be televised.
Update, Friday 3:43 pm: Anderson on Friday afternoon won his 400-meter hurdles prelims with a winning time of 50.19 to advance to Saturday's final, to be held at 3:15 p.m. PT. "It was really windy," said Anderson. "I wanted to stay relaxed and concentrate on some things we worked on in practice. Today was a light run for me and tomorrow I will pick it up."
The Olympic track and field trials (TV coverage on USA, NBC networks) start June 27 in Eugene, with the men's 400-meter hurdles final slated for that Sunday. The top three from the race make the U.S. team.
And currently, Anderson's time of 48.69 ranks No. 10 on the list of qualifiers' personal bests.
The thing about the 400-meters, though, is that the best performances are often run when the competition is the greatest. Indeed, as the level of competition has risen this year, Anderson's times have been faster and faster.
Who knows what kinds of times Anderson might put up over the next two weeks.
Anderson has said he plans to play football this season regardless of whether he makes the Olympics team, although that would be a tall order since at the same time the Olympics will be going on, Washington State will be immersed in their fall camp, and it would presumably take some time for Anderson to switch gears from track and get into football shape.
