Overall, six past, present and future Stanford swimmers finished among the top 17 in the morning preliminaries.
Katie Ledecky, who gave Stanford her verbal commitment and will be a senior in high school this fall, recorded the 13th-fastest time (54.96), followed by Stanford grad Andi Murez (14th in 54.97), Cardinal senior Maddy Schaefer (15th in 54.98) and grad Felicia Lee (17th in 55.14).
Stanford grad Maya DiRado swam the ninth-fastest time in the 200 fly, finishing her heat in 2:11.98 and earning a spot in the 'B' final.
