ZURICH, Aug 31 (Reuters) - Americans Noah Lyles and Sha'Carri Richardson cemented their status as fastest in the world this year with victories at the Weltklasse Diamond League meeting on Thursday.
Kyron McMaster of the British Virgin Islands handed world record holder Karsten Warholm his first 400 hurdles loss this season, taking victory in 47.27 to edge the weary-looking world champion Norwegian who crossed in 47.30.
The Olympic champion and twice reigning world champion failed on three attempts at 6.23 - what would have been the seventh time he has bettered the world record.
Winfred Yavi of Bahrain passed world record holder Beatrice Chepkoech of Kenya with a lap remaining in a carbon copy of her world victory to win the women's 3,000 steeplechase.
Yomif Kejelcha of Ethiopia won a men's 5,000 race in which Lamecha Girma, the world record holder in the 3,000 steeplechase, dropped out with two laps to go.
