It had been more than 13 years since three-time Olympic gold medalist Brendan Hansen set the national public high school 100-yard breaststroke record at Philadelphia's Haverford Senior High in 53.67 seconds on March 10, 2000.
Then three California prep swimmers eclipsed that mark in a single race.
Campolindo (Moraga, Calif.) High senior Steven Stumph touched the wall in 53.39 seconds to capture the North Coast Section title at the Concord (Calif.) Community Pool (h/t MaxPreps), edging out Miramonte (Orinda, Calif.) High senior Charlie Wiser (53.57) and Granada (Livermore, Calif.) High junior Nick Silverthorn (53.61).
"I haven't seen anything like it," Campolindo coach Ron Heidary told the Contra Costa Times. "I think the consensus from everybody I talked to was that was the most extraordinary heat of swimming that anybody has ever seen."
CollegeSwimming.com's No. 12 senior recruit, the USC-bound Stumph also won the 100-yard butterfly in a North Central Section record time of 47.88 seconds in addition to swimming the second leg of the winning 200-yard medley and 400-yard freestyle relay squads that finished in meet record times of 1:30.52 and 3:01.70, respectively.
Naturally, Stumph's Campolindo team cruised to the North Coast Section championship.
Meanwhile, the NCS title-winning Carondelet (Concord, Calif.) High girls squad also set a national prep record at the meet. Chelsea Chenault, Natalie Amberg, Madelyn Murphy and Madison White won the 400-yard freestyle relay in 3:20.42, eclipsing the previous mark of 3:21.63 set by Germantown (Washington, Pa.) Academy in February.
Ranked the No. 8 senior recruit by CollegeSwimming.com, the USC-bound Chenault also won individual NCS titles in the 200- and 500-yard freestyle in 1:44.45 and 4:39.11.
