Ottawa's Tabitha Baumann won the gold medal in the women's 1,500-metre freestyle on Thursday at the Santa Clara Grand Prix.
Baumann clocked a personal best 16 minutes and 37.08 seconds finishing ahead of Chare Escobar Torres of Mexico in second at 16:40.53 and Carolina Queiroz of Brazil third in 17:00.42.
"I wasn't expecting to post such a fast time," said Baumann, 17, the daughter of Canadian Olympic champion Alex Baumann. "It's a really good feeling."
Bridget Coley of Toronto was fourth in 17:00.49 and Heather Maitland of Toronto seventh.
In the men's 800-metre freestyle, two-time Olympic medallist Ryan Cochrane of Victoria took the bronze medal in 7:59.71. Connor Jaeger of the United States won the gold in a meet record 7:50.14 and Mack Horton of Australia was second in 7:59.64.
"It's not exactly what I expected," said Cochrane, tuning up for this summer's FINA World Championships. "I was happy though with how I controlled my stress and kept my good habits."
Competition continues through to Sunday.
