Olympics-Golf-South Korean Park leads by two heading into final day

RIO DE JANEIRO, Aug 19 (Reuters) - South Korea's Inbee Park shot a third-round 70 on Friday to increase her lead in the Olympic golf tournament to two strokes over New Zealand's Lydia Ko and American Gerina Piller. Park, who missed two months of the season due to injuries, started on the front foot with three early birdies but fell back after dropping three shots. Seven-times major champion Park, who is now 18 holes from winning the first gold medal awarded for women's golf since 1900, finished strongly, however, in windy conditions. "It was a struggle out there but I feel like I hung in there really nicely and I am very happy that I gave myself a chance tomorrow (Saturday)," the 28-year-old Park told reporters. "It was very, very windy... It is going to be tough finishing tomorrow, I think they are expecting bad weather so it is going to be maybe another one like today." After a sluggish first two days, world number one Ko raced up the leaderboard with a bogey-free six-under-par 65 courtesy of four birdies and a hole-in-one at the par-three eighth. "I made my first ever hole-in-one and for it to be at the Olympics, it doesn't get much better than that... I would have loved to have done a dance or jumped up and down but in that situation I was almost about to cry," the 19-year-old said. "To stand on that podium would be almost more than I could imagine. You just start imagining and dreaming about it... I think it would be a cool feeling, but you never really know until you are there." Piller, who carded a three-under-par 68, was determined to use her emotions to her advantage on the final day. "I'm gonna welcome them in my head. They're going to pop in there, you can't ignore it," she said. "If something comes in my head and I use that as motivation and just a lot of confidence. I think that's going to do me a lot of good." (Reporting by Shravanth Vijayakumar, editing by Ed Osmond)
