World record holder Ryan Murphy secured a spot on his second Olympic team with a win in the 100-meter backstroke Tuesday night at the U.S. Olympic Swimming Trials. 

Murphy, 25, went 52.33, just .15 ahead of second-place finisher Hunter Armstrong. Thirty-six-year-old Matt Grevers, the 2012 Olympic champion in the 100 back, finished sixth in 53.27.

Murphy set his world record at 51.85 while leading off the men's 4x100 medley relay at the Rio Olympics, where he also took gold individually in the 100 and 200 backstrokes. 


Since Rio, Murphy has mainly traded around podium finishes with backstroke rivals Evgeny Rylov, of Russia, and China's Xu Jiayu at major international meets. At the most recent world championships, Murphy missed out on a medal in the 100 back, finishing in fourth place by .01 seconds.  

Murphy's 52.22 semifinals performance in the 100 back marked his fastest time since 2018. He's also entered in the 100 fly and 200 back -- where he's the top seed -- later this week in Omaha.
