Ha-Neul Kim is the first round leader at the USGA LPGA US Womens Open at Sebonack Golf Club, in New York. Ha-Neul Kim / Getty Ha-Neul Kim, from South Korea, shot a first round -6 under par 66, to lead the US Womens Open after the first round at Sebonack Golf Club in New York. She leads by just one shot from countrywomen Inbee Park, who is in second place at -5 under par. Ha-Neul said through an interpreter; " This is my first time in U.S. Open, and I didn't think that I’m going to do it like this." Inbee, who won the Kraft Nabisco Championship and the Wegmans LPGA Championship earlier this year, is trying to become only the second player in LPGA history to win the first three Majors in a season. Babe Zaharias accomplished the feat in 1950 when she won all three majors played that year. Inbee, who open the championship with a round of -5 under par 67, her lowest ever score at a US Womens Open, was thankful of the USGA moving some of the tee's forward today; “The USGA was a little generous on us today, a lot of tees were moved up. So instead of hitting like 5‑irons, we were hitting 9‑irons, and that was making the course much easier. I was actually able to go for some pins and give myself a lot of opportunities today. Yeah, I made a lot of putts and didn't leave much out there. I do have a lot of confidence in myself at the moment, the way I'm playing, the way things have been going, the way I've been getting the luck, I think I am in the zone. I've been playing my best in my career at the moment. I really just want to enjoy the moment." Stacy Lewis, at -1 under par, was paired with Inbee today agreed that Inbee's putting is what makes the difference; " She putts like that every week, I mean, it's every round I play with her. She always putts like that. I think everything inside 10 feet, other than that last hole, she made everything. So that's the way Inbee plays. She's steady. She'll hit a bad drive here and there but she'll get up‑and‑down from 100 yards and that's just her game. I'm excited with the way I hit the ball, especially some of those shots I hit at the end into 6 and 7 were really good. So I'm excited about where my game is. This is not a tournament you want to lead after the first day because it's hard to maintain that for four days." There are four Ladies tied in third place, Caroline Hedwall, Anna Nordqvist, I.K. Kim and Lizette Salas, all at -4 under par. Caroline was pleased she was able to take advantage of the shorter course today; " It was definitely playing tougher during the practice rounds, but I think it was good that I could take advantage of the course playing a little shorter today. So I didn't really think about it that I duly made eight birdies. I was just on a good roll and I made a lot of putts. It was nice." It is a Major, and a long way to go, but Inbee is in form and full of confidence.
