University of Michigan senior Letitia Sim stole the show on the ultimate night of SEA Games competition with a 1:05.92 breaststroke split on Singapore’s meet record-breaking 400 medley relay.
Sim becomes just the 6th woman to split 1:05 or better on a long course medley relay this year, joining the elite contingent of Kate Douglass (US), Anna Elendt (DE), Tang Qianting (CN), Satomi Suzuki (JP), and Angharad Evans (GB). It beats the 1:07.87 split Sim produced for Singapore at the 2025 World Championships by nearly two seconds.
Sim led the team, which included Julia Shu Ning Yeo, Jing Wen Quah, and Ting Wen Quah to a 4:05.79 meet record.
Singapore had a banner day to close off their meet in Bangkok. Apart from the medley relay, they also had a gold medalist by 16 seconds (8:33.13) in the women’s 800 free, courtesy of Ching Hwee Gan. Zheng Wen Quah also capped off a successful meet with another gold, this time with a 2:00.62 effort in the men’s 200 back. Further, the men’s 50 breast went to Singaporean Chun Ho Chan with a 27.68 final time. Ting Wen Quah was Signapore’s icing on the cake, winning another gold at 33 years old in the 50 fly. Her 26.42 effort cleared the field by over a half second and established a new SEA Games Record.
