Lyles, the reigning Olympic champion, suffered a disastrous start and could not make up the difference as Bromell, a two-time world bronze medallist, stormed to the win in 9.91 seconds from lane eight."I'm good. The feeling at the start was not what I expected," said Lyles, who finished second, a hundredth of a second off Bromell.Switzerland's Audrey Werro continued her dominant form over 800m as she scorched to another victory, in a Diamond League record of 1min 53.80sec.Femke Broeders-Bol, the convert from 400m hurdles, was second in a personal best of 1:55.60 as she continued her transformation into a true two-lap competitor.Werro's time was the third fastest ever run, bettering her previous best set in Stockholm earlier this month by 0.18sec.The 22-year-old Swiss runner's performance saw her edge closer to the oldest world record in athletics -- the 1:53.28 for the outdoor 800m set by Jarmila Kratochvilova of the then-Czechoslovakia in 1983."I was not expecting to run this fast this season," said Werro, who credited her improving time to becoming a professional athlete no longer also juggling university studies."These recent performances have really given me hope and built my confidence to what is coming next."In the pole-vault, Duplantis, like Emmanouil Karalis, entered the competition at 5.63m, both skipping 5.73m.The Greek cleared 5.83m without a problem, Duplantis opting to sit that height out as the competition moved to the business end.
