Santa Margarita senior Darren Nguyen broke the 50-second barrier in the 100-yard butterfly event at the 51st Foothill Swim Games, touching the wall in a lifetime-best time of 49.74 seconds. Nguyen had been chasing the 50-second mark for nearly two years, finally achieving the feat in front of his cheering teammates. The performance was part of a dominant showing by the Santa Margarita boys and girls teams, who swept the team titles at the meet.

What they’re saying

“It's been a big goal of mine. I've been stuck at the 50 barrier for a minute now. It's good to see the training pay off, especially mid-season. I couldn't have done it without the guys. They're always pushing in practice and pushing me at meets.”

— Darren Nguyen, Swimmer

“I had a really slow start, really slow turn but that's because I don't have fast-twitch muscle fibers that are activated right now. Being able to go 20-point essentially with what feels like a push off the wall is pretty good. I'll take it.”

— Bennett Korner, Swimmer
