The New Zealand Olympian Nicky Samuels scored a dominating wire-to-wire victory in Korea for her second career International Triathlon Union World Cup title.
Her compatriot Rebecca Kingsford raced impressively for seventh at Tongyeong.
Following a successful two-woman bike breakaway with Korea's Yun-Jung Jang, Samuels held off the hard-charging Maria Czesnik from Poland and Japan's Yuka Sato to take gold in a time of 2 hours, 1 minute and 51 seconds.
The win and performance is a great boost for Samuels coming almost a month to the day out from the ITU World Triathlon Grand Final in Auckland
A relatively small field of about 30 women kicked off the day with a two-lap non-wetsuit swim in Tongyeong Bay.
Samuels did not waste any time asserting herself as the one to beat as she led the women out of the water.
Out onto the 5-lap 40km bike course, Samuels and Jang broke from the field and surged to the lead.
After the first lap, they built a 35-second lead, which grew to 50 seconds by the second lap.
The pack failed to close the gap and by the time they took the bell lap Samuels and Jang owned a lead of one minute, ten seconds.
Despite stepping onto the 4-lap, 10km run course at the same time, Samuels accelerated away from Jang almost immediately.
Jang's position near the front was short-lived and she was quickly reeled in by stronger runners like McShane and Sato.
The pair ran shoulder-to-shoulder as they attempted to close the gap to Samuels.
But they would soon find opposition from Czesnik who was storming through the field and passed McShane and Sato in the final lap.
As she approached the finish chute and stepped on the blue carpet, Samuels looked behind and knew victory was hers, triumphantly raising the finish tape for her second career World Cup victory.
