The USA College Challenge will be held Saturday and Sunday at the Uytengsu Aquatics Center on the USC campus.

Matt Anderson, Abrahm DeVine, Sam Perry, Grant Shoults and True Sweetser are making the top to L.A. on the men's side of the Pac-12 challenge.

For some, like Olympian Katie Ledecky, it's a typical whirlwind of events. For others, like Katie Drabot, Brooke Forde, Janet Hu and Ella Eastin, it's a reminder of a summer full of national and international events.

The first stop is the Pac-12 opener against the Utes on Friday at 1 p.m. The second stop is a conference challenge against the USA national swimming teams.

The itinerary for Stanford's opening weekend for both the men's and women's swimming teams includes stops in Salt Lake City and then split trips back to the Bay Area or to Los Angeles.

Stanford returns 12 of 15 All-Americans from last season, led by senior captain Sam Perry, who collected six All-America honors last season. Returning first-team All-Americans include Matt Anderson, Abrahm DeVine, Ryan Dudzinski, Liam Egan, Paly grad Andrew Liang, Ted Miclau, Perry and Grant Shoults.

"This is a talented class that will make strong contributions from top to bottom," said Knapp, who enters his sixth season as head of the program. "We're looking for them to contribute in both sprint and distance events, as well as both individual swims and relays."

"This team has developed a great attitude throughout the summer that excites them for more opportunities in 2018," Cardinal men's coach Ted Knapp said. "With another season of similar training to last season and a strong December invitational on the calendar, the team will once again contend for a top-five finish in March."

The Stanford women open the season as the defending NCAA champions and are ranked No. 1. The Cardinal men finished fifth at last year's national championships and are currently ranked third.

The Cardinal had 13 different All-Americans combine for 47 All-America honors, seven individual national championships and three relay titles during the four-day NCAA championship meet inside IUPUI Natatorium.

Last year, Stanford won its first NCAA title since 1998, and its 10th national championship overall (most in the nation).

The Stanford women have won 15 straight dual meets. The Cardinal's last defeat was to No. 3 Cal on Feb. 14, 2015. The Cardinal has also won 11 straight dual meets at home dating to Oct. 30, 2014 against Texas.

The Pac-12 Network is scheduled to air the College Swimming Challenge between the Pac-12 and USA Swimming.
