MELBOURNE, Australia (AP) – Leisel Jones broke her own world record in the 100-meter breaststroke at the Commonwealth Games, finishing in 1 minute, 05.09 seconds Monday.

The 20-year-old Australian, who has won three gold medals at the meet, set the previous mark of 1:05:71 in the same pool at the Melbourne Aquatic Center on Feb. 3 at the Australian Commonwealth Games trials.

“I’m in absolute shock,” Jones said. “I cannot believe it. It is absolutely amazing – I was so nervous beforehand I had (stomach) cramps.”

Jones thinks she can lower the mark even further.

“I think my stroke is going to get better and better and my strength is going to get better in the gym,” she said. “(A time of) 1:04 would be an absolute dream. I think it’s exciting to see what the future holds and see how much stronger I can get.”

Jones also holds the record in the 200 breaststroke. She was a surprise winner in the 50 breaststroke in her first final of the Commonwealth Games program, and added the 200 title on Saturday night.

Jones said was unhappy with her 200 time, and knew she would feel pressure from teammate Jade Edmistone, who holds the world record in the 50 breaststroke.

She was almost a half-second under world-record pace when she made the turn, and held it together on the second length.

“I was dying a fair bit, in every stroke I was pulling, and they were getting louder and louder – the crowd has a lot to do with it,” Jones said.

“It seems that 2006 has been the year for me. Getting a bit of balance has been the most important thing.”

As a 15-year-old, Jones won silver in the 100 breaststroke at the Sydney Olympics. Four years later in Athens, she took silver in the 200 and bronze in the 100.

She earned her first gold by winning the 100-200 double at the 2002 Manchester Commonwealth Games and also won the world championship in both events last year in Montreal.

“I still think my stroke needs improving,” she said. “I think there’s still things I can’t do yet.”
