Trinidad and Tobago's Olympic bronze medalist George Bovell III sent a strong warning to his rivals ahead of this month's London Olympic Games when he whipped his rivals in both the men's A 50 metres freestyle and backstroke finals on the final night of the Canada Cup on Sunday.

Swimming out of lane four in the 50m freestyle at the Montreal Olympic Park, the 28-year-old Bovell touched the wall in 22.01 seconds, well ahead of his Club Wolverine teammate Duje Draganja of Croatia who ended in 22.97 seconds.

Another of Bovell's training partners, American Robert Savulic took bronze in 23 seconds flat.

Earlier Sunday, Bovell had topped the field in the 50m freestyle heats in 22.31 seconds.

Bovell then outclassed the field in the 50m backstroke in 25.80 seconds to beat Charles Francis (26.04) and Jeffrey Swanston (26.49) into second and third place respectively.

In the morning heats, Bovell, a double gold and silver Pan American Games medalist clocked 26.45 seconds to finish behind Francis (26.22) as one of the top qualifier for the 50m backstroke final.

The US-based swimmer also captured bronze in the 100m freestyle A final on Friday night after teammate Milora Cavic took gold in 49.32 and Savulich, silver in 49.58.

For Bovell, the weekend outing was his first since winning a gold and two bronze at the Longhorn Aquatics Elite Invitational Meet in Texas during the first week of June.

The Canada Cup was his last competitive meet before the Olympics which runs from July 27 to August 12.

Bovell, a three-time Olympian, won bronze at the Athens Olympics in 2004 in the 200m individual medley.
