— Lawrence’s Michael Andrew placed fourth in the men’s 100-meter breaststroke semifinals at the U.S. Olympic Trials on Sunday, advancing to Monday's finals at CenturyLink Center.

The 100 breaststroke finals will be broadcast on NBC, with coverage beginning at 7 p.m.

Andrew, who finished in 59.85 seconds, will have to place within the top two to earn a spot on the Olympic team.

During prelims Sunday morning, Andrew, 17, set a junior world record while winning his heat in 59.96 seconds, becoming the youngest swimmer in U.S. history to finish under a minute in the event.

“Obviously I’m blown away right, because it’s the first time under a minute,” Andrew told after prelims. “It makes me really feel like world-class legit now. I’m excited.”

Lawrence High and Notre Dame graduate Emma Reaney took 74th in the women’s 100 butterfly, finishing in 1:01.15.

Also, Kansas University’s Chelsie Miller placed 52nd in the 400 individual medley, and Libby Walker was 84th.

The Trials will run through July 3.
