CHARLOTTE, N.C. -- Katerine Savard of Pont-Rouge, Que., won the gold medal Friday in the women's 100-metre butterfly and Canada added silver in both relays to open the fifth stop on the U.S. Grand Prix circuit in swimming.

Savard, tuning up for the Commonwealth Games and Pan Pacific Championships this summer, clocked 58.60 seconds with Claire Donahue of the United States second in 58.84 and Kristel Vourna of Greece third at 59.74.

In the men's 4x100-metre freestyle relay, Canada's male junior relay initiative tour team took the silver and bronze in its competitive debut. The silver medal winning team was comprised of Mitchel Ferraro of Uxbridge, Ont., Javier Acevedo of Ajax, Ont., Calgary's Yuri Kisil and Victoria's Stefan Milosevic. They clocked 3:24.09

The third place squad members were Gael Chaubet of Longueuil, Que., Toronto's Oliver Straszynski, Matthew Ackman of Pointe-Claire, Que., and Vancouver's Jonathan Brown in 3:29.24. The other four members of Male Junior Relay Initiative Tour team were fourth in 3:29.92 with Gavin Dyke of St. John's, N.L., Vancouver's Justin Chan, Montreal's Mirando Jarry and Vancouver's Marshal Parker. SwimMac from North Carolina took the gold in 3:23.92.

A junior male relay take-off camp was held last month as part of a strategy to develop the next generation of Canadian men's freestyle relay teams. The NFL-style combined camp focused on developing 4x100-metre and 4x200-metre freestyle relays and the swimmers executed anaerobic and endurance test sets as well as work on relay takeovers, strength and conditioning.

In the women's 4x100 freestyle relay, SwimMac won again in 3:44.60 with Swim Ontario second in 3:53.74 with Kennedy Goss of Toronto, Kylie Masse of Windsor, Keira Brazeau of Brockville and Annika Grewal of Oakville.

Ackman was also in two individual finals. He placed fourth in the 100-metre breaststroke in 1:02.89 just 0.17 seconds from a podium spot. He was also eighth in the 50-metre breaststroke.
