KUALA LUMPUR: Tern Jian Han, Wong Fu Kang, Chan Jie and Keith Lim smashed the country's long-standing national record in the men's 4x100m medley relay for a silver medal at the Singapore national age-group championships on Sunday.

The 20-year-old clocked 15:31.10 for his third title after wins in the 200m and 400m events.
Indonesian Perwira Aflah Fadlan and Singaporean Pang Sheng settled for silver (15:34.50) and bronze (16:03.97) respectively.
