FAST rising Katie Lau King-ting celebrated her recent call-up to the Hong Kong Commonwealth Games squad by stealing the limelight at yesterday's Mantas Invitational Meet at the Aberdeen Swimming Pool. Lau showed that she was ready to take over the mantle as the territory's fastest swimmer as she taught classmate and rival Robyn Lamsam a thing or two on her way to a record in the 15 and over girls' 100 metres butterfly. Lau, one of six Hong Kong swimmers chosen for the British Columbia Games this August, has been a revelation this year. She is already unofficially ranked 16th in the world in her speciality and looks destined for greater things. Her victory over Lamsam was one of nine age group records set, but more importantly it indicated that the 15-year-old Diocesan Girls' School pupil has a very bright future ahead of her. Lau slashed more than four seconds off the old record set by Christine Dullo as she churned the water to a new time of one minute, 3.55 seconds. Lamsam got herself on the record books by breaking her old mark in the 15 and over 200 metres freestyle. Lamsam, who will also compete in the Commonwealth Games, smashed Fenella Ng's record of 2:14.83 with a time of 2:08.71.
