BEIJING - The women's 100m hurdles has for a long time been known as Team USA's best event. However, at the 2015 World Championships that was not the case as all four U.S. women were left off the podium. 

#3 ranked, Dawn Harper-Nelson was eliminated during the semi-finals via a DNF.
#4 ranked, Kendra Harrison was eliminated during the semi-finals via a false start.
#1 ranked, Sharika Nelvis finished dead last in the finals.
#6 ranked and defending World Champion, Brianna Rollins finished 4th by 0.01

It's safe to say today was not a great day at the office for the U.S. 100m hurdlers.
