American Trayvon Brommel won the 100 meters and reigning world and Olympic champion Shaunae Miller-Uibo of the Bahamas won the 400 in feature races Saturday at the Oregon Relays. The meet, staged in breezy and wet weather, was the first elite event contested at the University of Oregon’s renovated Hayward Field, site of June’s US Olympic trials and next year’s IAAF World Championships. Brommel jumped ahead at the start and led all the way to win in 10.01sec with fast-closing world 200m champion Noah Lyles second in 10.17 and Liberia’s Emmanuel Matadi third in 10.19. “I started good, just tried to block out the weather and stay focused on the race,” Brommel said. “I was just happy.”
