KUALA LUMPUR: Swimmer Welson Sim rewrote his national record in the men's 400m freestyle event for Malaysia's second-ever title in the Mare Nostrum tour in Monaco on Sunday.
The 20-year-old did it in style by edging reigning Olympic champion Mack Horton of Australia for the gold medal.
Welson erased his previous record of 3:50.33 set in March last year by clocking 3:49.48 for the gold medal.
Horton posted 3:50.13 for the silver while China's Qiu Ziao took third on 3:51.18.
Phee Jinq En won Malaysia's first ever gold in the tour achieved in the women's 50m breaststroke also in Monaco last year.
