Brian Stuard and the other leaders never hit a third-round shot Saturday as Zurich Classic of New Orleans was halted by thunderstorms, raising the chance of a Monday finish for the event. Stuard, seeking his first professional victory, finished off a four-under-par 68 in round two Saturday morning, making four birdies while closing on the front nine to take a one-stroke lead over Jamie Lovemark and Venezuela's Jhonattan Vegas. Lovemark carded a 66 and Vegas a 69 — both wrapping up their second rounds on Friday, when there was no weather delay but darkness stopped play in a tournament still trying to catch up from a delay Thursday. Stuard, who had a 36-hole total of 12-under par 132, said it was too soon to start thinking about a victory. "We have a long way to go. I'm just kind of focusing on the next shot, and we'll see what happens," added the American, who is playing in his 101st PGA Tour tournament with his best results second-place finishes in the 2010 and 2014 OHL Classic at Mayakoba. An Byeong-hun of South Korea, the 2014 winner in New Orleans, posted a second straight 68 and was three shots back in a tie for fourth with Harold Varner (67), Daniel Berger (65), Charles Howell (69), Patrick Rodgers (69) and Chad Collins (64). World No. 1 Jason Day of Australia was five strokes back in a group sharing 10th after a 68 for 137. More rain was forecast for Sunday, and tournament director Steve Carman said any further weather delays would result in a Monday finish. Piller leads LPGA American Gerina Piller produced another ball-striking clinic in the third round at the Texas Shootout Saturday to earn a two-shot lead and put herself in position for her first LPGA title. The world No. 20, in her sixth LPGA season, hit 18 greens in regulation for the second straight day, en route to a bogey-free four-under-par 67 at Las Colinas Country Club in Irving. Piller will start the final round Sunday at 14-under 199, with South Koreans Amy Yang (65) and Hur Mi-jung (66) her closest pursuers on 12-under. Piller began the third round with a one-shot lead over South Korean Ji Eun-hee, who carded 71 to drop back into a tie for sixth.
