OMAHA — Olympic champion Nathan Adrian and Ryan Lochte safely qualified into the Olympic Trials 100m free semifinals Wednesday, but Lochte later scratched out of the event.
Adrian was the fastest qualifier in 48.83 seconds. Lochte, battling a groin injury, was sixth in 49.13. Adrian and Lochte bookended the 2012 U.S. Olympic 4x100m free relay that earned silver behind France.
Lochte was not expected to have designs on making the Olympic team in the 100m free, and even though he scratched he is still eligible for the 4x100m free relay since he already made the Olympic team in the 4x200m free.
Cullen Jones, a 2008 and 2012 Olympic 4x100m free relay member, was 29th overall in prelims and failed to make the 16-swimmer semifinals. He has one more shot to make the Olympic team in the 50m free later this week.
Matt Grevers, an Olympic 4x100m free relay prelim swimmer in 2008 and 2012, got the last of 16 semifinal spots by .03 of a second. Grevers finished third in the 100m backstroke final Tuesday, failing in his best chance to make the Olympic team.
The 100m free semifinals are Wednesday night (8 ET, NBC and NBC Sports app). The top eight from the two semis will advance to Thursday night’s final, where the top two make the Olympic team individually and as many as the top six for the 4x100m free relay.
None of Michael Phelps, Missy Franklin or Katie Ledecky were in action Wednesday morning, but all are in finals Wednesday night.
In the 200m butterfly, Phelps will look to become the first U.S. male swimmer to make five Olympic teams. He is the top seed.
In the 200m freestyle, Ledecky will look to win her second event of Trials after taking the 400m freestyle Sunday.
Franklin, who finished fifth in the 100m backstroke Tuesday, will look to get on the Rio team here after qualifying fourth out of Tuesday’s semifinals. A top-six finish will likely be enough to get on the 4x200m free relay.Follow @nzaccardi
