Maguire hauls herself into contention with super 65
Leona Maguire belied her amateur status in a world-class field as she shot a superb 65 in round two of the women's Olympic competition in Rio.
The 21-year-old bounced back in spectacular fashion from an opening 74 to register her credentials for a medal challenge with a six-under-par second-round display.
Her three-under total placed her tied for 22nd place, but just seven shots separated the Duke University student from overnight leader Inbee Park of South Korea.
Park's second successive 66 for 10-under-par gave her a one shot lead ahead of Stacy Lewis (USA), who shot a best-of-the-day 63.
Charley Hull of Great Britain and Canada's Brooke Henderson were next best on eight under.
The scoring was impressive from a field packed with players from the elite LPGA Tour.
Of the 60 competitors in the competition, 37 were under par, but to illustrate Maguire's achievement, her 65 was one of the top four scores on the day.
Only Lewis (63) and Henderson (64) shot lower than Maguire, whose 65 was matched by Yang Hee Young of Korea.
The Irish Olympian filed a card containing seven birdies and just one bogey.
A birdie four on the par-five 10th hole gave Maguire some payback for a double-bogey seven in round one.
Jordanstown's Stephanie Meadow, the other Irish player in action, delivered an impressive 66 for one over overall and tied-38 place.
