Caroline Masson / Getty Images Caroline Masson leads the North Texas LPGA Open with a career best score of -7 under par 64, to capture the lead at Las Colinas Country Club in Irving, Texas. Caroline said she was bothered by the traditional Texas wind during her round; “For some reason I feel like I'm playing pretty good in the wind. My win on the LET in South Africa was also in like really, really windy conditions. And yeah, I'm hitting it well, so I think the wind doesn't affect my ball too much, and that will definitely help me throughout the week. But it's just also important to just make some putts on these greens because without putting well, I think you have no chance to shoot a really good round here. So it's just all coming together really.” Coming up behind Caroline are three players at -4 under par, starting with current Rolex Rankings No. 1 Inbee Park, then Mo Martin and 2009 U.S. Solheim Cup Team member Kristy McPherson, all had rounds of 67 . Inbee said she was very happy with fast greens here; " It was quite different with the speed because it's such a difference from last week but I'm very glad that I'm playing the fast greens. I love fast greens, rolling greens. Last week was a very big challenge for me with slow and grainy greens which I struggle, but I was able to play better last week. So this is tough to adjust, but I love the greens here." There will be a cut here, so the top 70 and ties following Friday’s second round will go forward. As part of the “Shootout” format, there will also be a another cut on Saturday which will reduce the field to the top 50 players and ties.
