Worrell off to mighty start at US nationals

Michael Phelps is eager to see where he stacks up against the world at the US national championships.

Kelsi Worrell got her answer on Thursday night: She has suddenly emerged as an Olympic contender with the Rio Games just a year away.

With Phelps on the sideline for the opening day of the meet, Worrell grabbed the spotlight by winning the women's 100m butterfly with a time that would have been good enough for a bronze medal at the FINA world championships in Kazan, Russia.
