Pornanong Phatlum leads the Lorena Ochoa Invitational at the conclusion of play on day 1 at the Guadalajara Country Club, in Mexico. Pornanong Phatlum / Getty Pornanong, in search of her first LPGA Victory, shot a 6-under 66 to take the first-round lead at the sixth annual Lorena Ochoa Invitational presented by Banamex, in Mexico. Pornanong said it was the putting that was the difference today; " Well, today, my putting was very good, I had a complete game today. There are not many players this week, I just want to have fun on the course this week.” Amy Yang who only needed 29 putts on a round that included six birdies and one bogey is in second place, just one shot back at -5 under par. She carded three consecutive birdies beginning at the par-4 fourth and also said it was the putting that made the difference; “I think I did everything so well today, especially putter, I felt really good over the ball every time. It really helped, I had some chance to win before. When I didn't achieve it, I was wondering if I can do it or not. But since the first win, I give a lot of confidence, and now I'm enjoying it more.” Tied in third spot at -4 under par are Rolex Rankings leader Inbee Park, Anna Nordquist and So Yeon Ryu. Inbee reported that she had played well, the only problem was mud on the ball; “My ball striking was really good today, I hardly missed any shots out there today, I didn’t miss any fairways and probably missed only a couple greens but I was getting some muddy balls there and just didn’t know where it was going to fly. I left a couple of putts out there today and I had a lot of opportunities. My ball striking was really good today though so hopefully I can keep it going the next three days. I mean last few weeks, last few months actually it’s been a little bit frustrating with the putter. When I am hitting the ball good and not being able to score well because of the putting, that is a little bit disappointing. But earlier in the year I made so many putts I maybe that’s why because it’s not going in at the moment as much but my time will come, I am trying got be patient.” If Inbee wins this week’s event she will clinch Rolex Player of the Year honors, and while there is a lot on the line, she admits once the tournament starts, her nerves quickly subside; " Actually today I felt actually a lot more relaxed than when I came in here. Once the tournament starts I don’t really think about Player of the Year. I think about it probably right after and before the play, but during the play I just try to think about the game." Seems like the girls are in the best part of Mexico right now, no rain where they are, unlike the boys who have had play suspended in their competition.
