Personal bests are sending sprinter Allyson Felix and hurdler Aries Merritt to London.

Felix won the women's 200 meters at the U.S. track trials Saturday in a meet-record 21.69 seconds. Wearing bright yellow socks that blurred with each stride, Felix finished well ahead of Carmelita Jeter in 22.11 and Sanya Richards-Ross in 22.22.

Moments earlier, Merritt posted the best time in the world this year in the 110 hurdles, winning in 12.93 seconds. Jason Richardson, the reigning world champion, was second in 12.98 and Jeffrey Porter finished third in 13.08 to round out the team for the London Games.

The seventh day of the event At Hayward Field started with Trevor Barron's merican record in the men's 20,000-meter race walk. He finished in 1 hour, 23 minutes.
