The 2011 outdoor season saw her repeat her Pac-10-second place, and a personal record of 56.04 seconds in the NCAA semi-finals led to a sixth-place finish in the 400 m hurdles final.

In her IAAF Diamond League debut, she placed fourth at the Shanghai Golden Grand Prix with a time of 54.74 seconds.
