Billy Horschel battles on at the top of the leaderboard at the Valero Texas Open at TPC San Antonio, AT&T Oaks Course. Billy Horschel / Cohen / Getty Images Billy Horschel shot a third round -2 under par 70, to lead the field at the Valero Texas Open by a comfortable two shots with a -10 under par total. Billy is full of confidence, and is no shrinking violet when it comes to making statements about his ability; " I've never been star struck out here, I respect all the veterans out here. I respect everyone that's put their time in out here. But at the same time, I'm as confident as I've ever been, and I feel just as good as anyone else in the world right now. I didn't even know I fell out of the lead until someone just told me, I couldn't care less whether I was leading after eight holes or whether I'm leading right now. I knew that I was playing well. I'm trying to stay loose, I think I've learned in the past that the looser I am, the more it helps." Tied in second place at -8 under par are Jim Furyk and Charley Hoffman, Jim with a third round of -3 under par and Charley had a -2 under par score on the day. Jim will partner Billy for the final round, thanks to the former U.S. Champion's consistent form from tee to green, Jim hit fifteen greens in regulation, a remarkable feat as the San Antonio wind switched to the South for the first time during the tournament. "It was funny to wake up and have the wind the dead opposite. What I was hitting hybrid into Thursday and Friday, I'm hitting 9-iron today. I'm glad I got a couple rounds under my belt before that wind switched." Sharing fourth spot at -6 under par, are Ryan Palmer, with a -4 under par 68 round today; Bob Estes, -3 under par 69, and World Number two Rory McIlroy, scrambling home with -1 under par round of 71. Rory is now four shots off the lead and will need a really low round tomorrow if he is to contest this title. It seems unlikely as he only managed to get on seven out of the fourteen 14 fairways, this was for the second time in the tournament, continuing his trend of up-and-down play this year after an off-season equipment change. " It was a tough scoring day, It was hard to really go low under par. I probably should have been a couple better, but at the end of the day, it's still a solid round, and I still have a chance coming into tomorrow." Bob Estes is not even thinking about the Masters, just tomorrow; " I don’t like talking about it, I’m just thinking about tomorrow. There’s plenty to stress out about, think about, playing in this wind. It’s just course management, a lot of guys, when the wind is blowing, they have trouble keeping it down or playing the right shot, and sometimes you have to play some pretty good defense. You play too aggressively in certain places and you hardly have a chance to two-putt or get it up and down." If the wind does blow at up to 25 mph tomorrow, I guess anything could happen, but I don't expect Billy Horschel to let another victory chance slip through his fingers.
