DES MOINES, Iowa (AP) – Tyson Gay completed the 100-200 sprint double Sunday at U.S. track championships, winning the 200 meters in 19.74 seconds Sunday and holding off Isiah Young. It’s the fastest time in the world this season. Gay beat Justin Gatlin in the 100 on Friday in a season-leading time of 9.75.
 
Kimberlyn Duncan upset Olympic champion Allyson Felix in the women’s 200. Duncan finished in 21.80, with Felix 0.05 seconds behind. Jeneba Tarmoh was third. Gay built a lead after the curve and then fended off the hard-charging Young, who finished in 19.86. Curtis Mitchell was third and Wallace Spearmon, a three-time U.S. outdoor champion, wound up fourth.
 
His hip fully healed, Gay looked sharp throughout nationals, setting up a matchup with Usain Bolt at the world championships in Moscow this summer.
