Tosky also finished second, and was the top American, in the 200 fly in 2:10.89. Canada's Audrey LaCroix won the race in 2:08.64.
On Saturday, Tosky also finished eighth in the 50 free, swimming a confounding 33.60. And no, she didn't cramp up during the race. She choose to swim the breaststroke.
"I had an open lane next to me, so I thought I would take advantage," Tosky said, smiling. "Dave (USC coach Dave Salo) liked it. I'm not sure what (Palo Alto Stanford Aquatics coach) Tony (Batis) thought."
Tosky earned one of her two All-American honors during her first collegiate season the 200-yard fly, finishing fifth at the NCAA championship in Indianapolis with a time of 1:55.11. She also earned an All-American award with the 800 free relay team, which finished sixth.
Tosky will be back in Indianapolis for the U.S. National Championships that begin June 25. She'll be focusing on the 200 fly, 200 free and 200 IM, although she may throw in a 50-meter event just for fun.
"We really did a lot of experimenting at USC," Tosky said. "I wanted to try different things and I think that I benefited from that."
She swam the Trojans' best times of the season in the 200 fly (1:53.98) and 200 free (1:45.14) and helped set the school record in the 200 free relay (1:28.42).
Tosky swam in eight events during the Santa Clara Grand Prix, including two relays. She swam in three 'A' finals and a 'B' final.
The PASA 800 free relay team, which also included Sacred Heart Prep junior Ally Howe, Gunn sophomore Jennifer Campbell and California sophomore Camille Cheng, finished second on Saturday.
PASA's 400 medley relay team, with Tosky, Campbell, Howe and Monta Vista junior Sarah Kaunitz, was fifth.
Tosky appeared tired on Friday and Saturday, seemingly pushing herself through every event. Sunday, she seemed fresh, relaxed and smooth.
"I usually do better later in a meet," Tosky said. "I was tired early but it was more mentally tiring. I've been training a lot and it's been rough, but worked out better."
One of the first things she learned about college swimming was the training done outside the pool.
"I lifted a lot more and changed my training," Tosky said. "When I got back with PASA, the sets were just as hard as I remember them."
She also trained alongside the Trojan Swim Club occasionally and found the experience eye-opening.
"Here are some of the greatest swimmers in the world and the guys would talk about surfing," Tosky said. "It made me realize there is a time to focus and a time to have fun. I've tried surfing but I also don't go to the beach a lot."
Tosky already has qualified for the World University Games, which get underway in Kazan, Russia on July 6, in both the 100 fly and 200 fly. She's hoping to finish among the top two at the national championships, which also serve as the world trials, and change her itinerary to include Barcelona for the World Championships that start July 16.
Gunn grad Rachael Acker and Palo Alto grad Liv Jensen are also qualified for the University Games.
