Brianna Rollins won ahead of her compatriots, second placed Nia Ali, right and Kristi Castlin, left Next up is the 100m hurdles. We have three Americans - Nia Ali, Brianna Rollins and Kristi Castlin - and two Brits - Tiffany Porter and Cindy Ofili - in this one. But Rollins is the huge favorite in this, she’s over 0.10 seconds faster than the rest of the field this year. And it’s her birthday tomorrow. Rollins wins, Ali is second and ... Castlin wins bronze. That’s a US sweep - not country has ever done so in this event. Rollins win was never in doubt but Castlin inched Ofili by 0.02 secs.
