RIO DE JANEIRO — American Brianna Rollins started out fast and never looked back.
Rollins led the U.S. sweep of the 100-meter hurdles at the Rio Games on Wednesday night, winning with 12.48 seconds.
Though Rollins was unreachable, it came down to hundredths of seconds for the other two medals.
Nia Ali had silver with 12.59 and Kristi Castlin had 12.61 for bronze.
