Steely Park holds off Ko in the heat

Nerveless Park In-bee sealed a wire-to-wire victory at the HSBC Women's Champions on Sunday in a clear statement of her intent to win back the No 1 ranking from Lydia Ko.

On a day of iced towels and umbrellas, the South Korean stayed cool in the Singapore heat for two-under-par 70 and a two-stroke win over Ko as she finished the week bogey-free.

Park's scores of 66, 69, 68 and 70 and aggregate of 15-under 273 were too much for Ko, 17, golf's youngest ever No 1 who was unable to erase her two-shot overnight deficit.
