Team USA is dominating the medal count at the 2016 Rio Olympics, and three women on the U.S. track team just hopped their way to another historic victory.

On Wednesday, Brianna Rollins, Nia Ali and Kristi Castlin made history in the women's 100-meter hurdles by winning gold, silver and bronze in a medals' sweep, USA Today reports. It is first milestone of its kind in the event in Olympic history.

Rollins came in first with a speedy time of 12.48, Ali in second with 12.59 and Castlin in third with 12.61. Rollins has the fourth-fastest time in Olympic hurdles history.

After winning bronze, Castlin told USA Today that her Olympic medal was in tribute to all those who are impacted by gun violence.

"I would like to dedicate this medal to victims of gun violence,'' Castlin said to USA Today. "Women hurdlers are so strong in the U.S., and we have overcome controversy. We are three strong hurdlers."

Ali made an incredible feat as a silver-medalist: She won the medal after taking a one-year hiatus after giving birth and caring for her son who is 15 months old.

Rollins has only nine years of experience as a hurdles sprinter. She began running professionally under Coach Carmen Jackson in the Liberty City neighborhood of Miami when she was a freshman at Miami Northwestern High School. 

Rollins never raced before then. According to the Miami Herald, Rollins only raced with the boys on her block. She always won.

Coach Jackson was a little hesitant at first, but eventually took her under her wing. Within a few years, under Jackson's coaching, Rollins went on to attend and compete for Clemson University. 

Way to go, Team USA!
