MANCHESTER, England – Jennifer Carroll of Montreal broke the Canadian record twice on Thursday in the women’s 50-metre butterfly at the world short course swimming championships.

Carroll initially lowered the mark to 26.92 seconds for 15th place in the preliminaries then smashshed it with a 26.65 clloking in the semis for 13th place overall. The previous mark was 27 seconds flat set by Nadine Rolland of Montreal in 2001.

The top-eight from the semis advanced to Friday’s finals.

‘’She had a much stronger swim in the semis,’’ said Pierre Lafontaine, Swimming Canada’s CEO and national coach. ‘’She was much more in control and didn’t rush her technique. In the prelims, her last three or four strokes were out of synch. She’s just going to get better as the week progresses.’’

Carroll is the last Canadian to win a world short course title raking the 50 backstroke in 2004.

American Jessica Hardy kept the world records flowing with a victory in the women’s 50 breaststroke. Hardy, who won the world long-course title in 2007, clocked 29.58 seconds to beat the 29.90 set by Australia’s Jade Edmistone in Brisbane in 2004. It took the world record tally to four after three marks tumbled on Wednesday’s opening night.

Callum Ng is in action Friday in the men’s 50 backstroke.
