Simone Manuel highlighted the prelims and evening sessions during the first day of the Art Adamson Invitational on Thursday in College Station, Texas, with a pair of the nation's best freestyle swims to date.
Manuel produced an NCAA A-cut 21.81 in the 50-yard freestyle during the morning, lowered it to a Stanford record of 21.59 in the evening and then went 45.81 during the 100-yard freestyle leg of the 400-yard medley relay.
"Simone Manuel will get a lot of credit, and deservedly so, for her performances tonight, but we had great performances all around," Stanford coach Greg Meehan said. "Grace Carlson, Heidi Poppe, Janet Hu, Sarah Haase and Julia Anderson were among those who stood out. The fact that our 'B' and 'C' relays were competitive across the board is really exciting."
Manuel's school-record 50 free tops Betsy Webb and Maddy Schaefer's 21.78 set in 2012 and 2014, respectively, but her 100-yard free split is what had the swimming world buzzing.
The Texas native already owns the 100-yard free American record, 46.75 set in March, a mark she clearly showed she is ready to lower.
Stanford won both relays, the medley and 200-yard freestyle relay, and added Manuel's 50 free first-place showing to take three of the first six events at the three-day invitational.
The freshman, swimming just 100 miles from her hometown of Sugarland, was on both squads and contributed to the freestyle relay win along with classmate Janet Hu, senior Maddy Schaefer and sophomore Lia Neal.
Hu doubled up as a winner in the medley relay with Manuel, while freshman Ally Howe and junior Sarah Haase helped the Cardinal win by more than four seconds.
Schaefer was second in the 50 free with a 21.93 and Hu followed at 22.08.
Julia Anderson narrowly missed a personal record in the 500-yard free by clocking at 4:43.89 to finish third.
Kassidy Cook, another Texas native, was third in the 3-meter diving competition.
"All around, we are racing well, but more importantly we are learning what we need to focus in on for success in March," Meehan said.
Stanford is in second place with 359.5 points behind host Texas A&M (384) in the eight-team field.
No. 10 Stanford leads a seven-team field at the Art Adamson Invitational hosted by Texas A&M after the first day of battle.
The Cardinal finished with 512 points while competing in six events Thursday.
Kristian Ipsen won the 1-meter diving event with 413.55 points.
Danny Thomson (4:20.31) and Drew Cosgarea (4:24.35) produced NCAA B-cuts while going 1-2 in the 500-yard freestyle.
Stanford took the top six five spots with as many NCAA B-cuts in the 200-yard freestyle, receiving the efforts from David Nolan (1:43.24), Max Williamson (1:45.69), Tom Kremer (1:45.70), Gray Umbach (1:46.12) and Curtis Ogren (1:46.77).
Nolan, Sam Perry, Connor Black and Thomas Stephens went 1:18.78 to capture the 200-yard freestyle relay.
Black went on to win the 50-yard freestyle in 19.89, and Perry touched third with a 20.07.
