AVONDALE, Louisiana — American Billy Horschel charged ahead with six consecutive birdies, then held his nerve down the stretch to win his maiden PGA Tour title by one shot at the Zurich Classic of New Orleans Sunday.



Two strokes off the pace going into a weather-disrupted final round, Horschel took advantage of rain-softened conditions and preferred lies at the TPC Louisiana as he sealed his long-awaited breakthrough victory with an eight-under-par 64.



The slim 26-year-old, who had recorded top-10s in his three previous starts on the US circuit, stunningly drained a 26-foot birdie putt at the par-five last to post a 20-under total of 268.



Horschel repeatedly pumped his right fist in delight after his ball disappeared into the cup for his ninth birdie of the day, then removed his cap to acknowledge loud cheers from the gallery packed around the 18th green.



"Oh man, it's something I have worked so hard for and there are so many people I need to thank. And they all know who they are," an emotional Horschel told Golf Channel after coping with two weather delays during the final round.



Fellow American D.A. Points, playing with Horschel, had been tied for the lead with three holes remaining but settled for second place after closing with a seven-birdie 65.



Kyle Stanley shot a 5-under 67 to finish third, while Chinese 14-year-old amateur Guan Tianlang finished 71st after making his second cut in two PGA events, the first coming famously at the Masters.



Overnight leader and 2009 US Open champion Lucas Glover, bidding for his fourth PGA Tour victory, fell back with an early bogey on the way to a 71 and a tie for fourth at 15-under.



Although Horschel had never won on the Tour, he had been playing the best golf of his young career lately, with three top 10 finishes in his past three tournaments — tying for second in Houston, tying for third in San Antonio and tying for ninth in Hilton Head Island, S.C., a week ago.



He has also made a PGA Tour-leading 23 straight cuts, and had already earned $1.3 million this year. Now he has nearly doubled that, thanks to a final round which tied a single-round course record that has been matched several times, including by Rickey Barnes in Thursday's first round.



British world No. 4 Justin Rose, the highest-ranked player in the field, closed with a 69 to tie for 15th at 12-under, level with 2012 Masters champion Bubba Watson (66) and four-time major winner Ernie Els (68).



Park wins North Texas



World No. 1 Park In-Bee drained a birdie putt at the final hole Sunday to win the inaugural North Texas LPGA Shootout, holding off Spain's Carlota Ciganda by one stroke. Park claimed the sixth LPGA title of her career and her third this year, a run of success that saw her rise to No. 1 in the world this month — one week after her major victory at the Kraft Nabisco Championship.



The South Korean played steady golf, posting four birdies without a bogey, her four-under 67 at Las Colinas giving her a 13-under total of 271.



Ciganda, who kept the pressure on Park with her own birdie at 18, finished with a one-under 70 for 272.



Norway's Suzann Pettersen carded a final-round 66 to claim third place on 274.



South Koreans Park Hee-young and Ryu So-yeon shared fourth on 275, Park after a blazing seven-under 64 that included seven birdies with no bogeys and Ryu with a 68.



South Korean I.K. Kim finished alone in sixth after a 68 for 276. — Agencies
