INDIANAPOLIS — With a string of perfect 10s, Laura Wilkinson and Troy Dumais appear to be Beijing bound.

Wilkinson, who won gold on the 10-meter platform at the 2000 Olympics, showed she's still the boss of the tower at the U.S. Olympic trials, holding off a challenger half her age in the semifinals tonight.

The 30-year-old Texan received at least one 10 on three of her five dives and finished with 813.20 points. She had a comfortable advantage over 15-year-old Haley Ishimatsu, who finished with four 10s and the highest-scoring dive of the night but was still only second at 757.55.

Wilkinson can lock up her third trip to the Olympics in the finals Sunday.

Dumais, who declared his goal for Beijing was "gold or go home," was just as good in the semis of 3-meter springboard. The two-time Olympian received 10s on three of his six dives to build a commanding lead with 1038.30 points. Chris Colwill was second at 961.00.

The springboard finals are Saturday.
