EUGENE, Ore. – Hayward Field has been dubbed as the site of the "toughest team to make" but it was most likely in reference to the women's 100-meter hurdles.
The United States came in with nine women ranked in the top 10 in the world but only three would go on to represent the United States at the Summer Games in Rio de Janeiro.
Former American record holder Brianna Rollins ran a 12.34 on Friday in the final to dominate a star-studded U.S. field.
She will be joined in Rio by Kristi Castlin, who ran a personal best of 12.50 in the final, and Nia Ali, a two-time world indoor champion in the 60-meter hurdles.
The race was also the first time that seven women have run 12.75 or quicker in the same 100-meter hurdle race at any national championships in history, according to Jon Mulkeen of the IAAF.
The United States has a chance of sweeping the medals in Brazil, a feat never accomplished by any country. Dawn Hunter, the 2008 Olympic champion, did not make the final but won a silver medal in London. Kellie Wells of the U.S. took bronze in 2012 as well.
Former NCAA champion Keni Harrison, who broke Rollins’s record with a 12:24 at the Prefontaine Classic in June, the second-fastest of alltime, failed to make the team.
