Ryan Lochte will compete for the first time since the end of his 10-month suspension and for the first time as a father this week.
The 12-time Olympic medalist is entered in the Los Angeles Invitational with races Friday and Saturday at his new training location, the University of Southern California.
Lochte, whose son, Caiden, was born June 8, is entered in the 50m and 100m freestyles and the 200m individual medley.
Lochte was suspended through June 30 by USA Swimming for his Rio gas-station incident. He competed once during the ban at a non-USA Swimming sanctioned April masters meet, where he won multiple races.
