Natalie Gulbis / Getty Images Natalie is joined at the top of the leaderboard by Gerina Piller and Pornanong Phatlum after three rounds of play at the season-ending CME Group Titleholders on the Tiburón Golf Club course in Naples. All three ladies stand at -11 under par for the tournament. Natalie shooting a third round -7 under par 65, with Gerina and Phatlum both recording third rounds of -5 under par 67. Natalie has switched to TaylorMade irons and needed coach Butch Harmon to sort her game out. Natalie and Butch both recommend using Winn Grips, which why we here at White Dragon Golf fit Winn Grips to our putters, the only manufacturer to do so. Natalie said she had been off for three weeks working to improve her game; “I've been off for three weeks and I've been home in Las Vegas working with my coach, Butch Harmon. I didn't play that well in Asia and there was a lot to do on my golf game. I changed irons, which as any player knows it's quite a process to change irons and switch to the new TaylorMade irons and just spent a lot of time with Butch redoing every aspect of my game and just working on fundamentals.” Gerina needs to convince herself not to be nervous on the first tee; “Tomorrow I think I'm just going to keep telling myself what I've been telling myself, when you stand on that first tee, just because you're nervous doesn't mean you're going to hit a bad shot. I feel like I'm striking it well and this win would be. I mean, just winning has always been a goal of mine and I've never won as a professional. So, for one, I'm excited that I put myself in this position to begin with and just have fun with it. It's the last round of the year." Phatlum said she was concentrating on her putting; " I just like more focused about putting because I feel comfortable about hitting and today hitting very good, putting today. Tomorrow would be get a lot of pressure. I want to try like stay on my game and trust in myself to do every shot by shot." Stacy Lewis shot the round of the day and in doing so set a new tournament record with a -9 under par 63. Stacy tied her career low, which she shot previously on three separate occasions. She carded eight birdies, an eagle and one bogey to jump from T23 to a tie for fourth place. Hitting the ball better was the key to her magical round; " I hit the ball a lot better. Kind of just all week just been working on my swing, working on my putting and just I found a couple things that clicked yesterday afternoon and then this morning. I mean, the hole‑out was definitely a nice way to get started and then from there it was actually pretty easy. I wanted to play good today just to kind of take all the worry out of tomorrow for Vare Trophy. I definitely overachieved what I thought I could do on this golf course, so I'm right back in the mix of things. I think I'm going to have to do it again, probably maybe not as low, but it's got to be a good one again tomorrow to be there. The leader for the first two days Sandra Gal sadly suffered a slump in round three carding a +2 over par 74, to be in a tie for fourth place with Stacy, Lexi and Shanshan.
