WATERLOO, Ontario, Canada -- Hee Young Park of South Korea shot a blistering 10-under-par 61, the lowest score of her career, on Saturday to take a one-stroke lead over Angela Stanford after three rounds in the Manulife Financial LPGA Classic at Grey Silo Golf Course.
The 26-year-old Park, whose only LPGA Tour victory came in the 2011 CME Group Titleholders after she won six times on the LPGA of Korea Tour, collected eight birdies and an eagle in her bogey-free round.
Park's previous best was a 63 in the final round of the 2010 LPGA State Farm Classic, which lifted her to a tie for fourth.
Stanford, looking for her sixth LPGA Tour victory, followed up rounds of 63-67 with a bogey-free 64.
Catriona Matthew of Scotland, coming off rounds of 63-64 that gave her a three-stroke lead after 36 holes, was tied for the lead with Park before carding a double-bogey 5 on the 12th hole en route to a 68 and is two shots back in third.
Meena Lee of South Korea shot 65 and is tied for fourth with Anna Nordqvist of Sweden, who carded a 67.
Inbee Park of South Korea, who has taken a firm hold on the No. 1 spot in the Rolex Women' World Rankings by winning six times this year including the first three majors of the season, posted a 68 and is tied for ninth.
Gerina Pillar, who has never won in three seasons on the LPGA Tour, made the biggest move of the day with a career-best 62, climbing 30 spots into a tie for sixth, six strokes back heading to the final round.
