Billy Horschel got his first career win Sunday, capturing the Zurich Classic of New Orleans by a stroke after a final-round 64 that included a birdie on the last hole to win by one.

Congratulate Horschel below, and we'll pass along your comments.

After three straight top 10s, including a runner-up, Billy Horschel did one better Sunday at TPC Louisiana.

Horschel shot a course-record tying 64 to get his first career victory, winning the Zurich Classic of New Orleans.

D.A. Points shot 65 to finish second, one shot behind.

Afterward, Horschel fell to the ground and broke down.

"I let it go," he said. "It all came out."

With the win, Horschel earns 500 FedExCup points and moves to third in the standings.

After being sidelined with a wrist injury early in 2010, Horschel, 26, has been knocking on the door over the last month.

He finished second to Points in Houston then tied for third a week later in San Antonio.

Horschel again had a chance to win last week, too, at the RBC Heritage but shot a final-round 74 to finish ninth.

Sunday, was a different story.

Entering the week 108th in final-round scoring average, Horschel was nearly flawless, making nine birdies and one bogey.

In the end, he needed every one of them.

Horschel at one point made six in a row in the middle of his round -- matching the longest streak on the PGA TOUR this season -- before adding the clinching birdie on the final hole.

Following the second of two weather delays and some nine hours after they began their round, Horschel and Points returned to hit their final shots.

Horschel landed 27 feet away before Points splashed out of a greenside bunker to 6 feet.

It didn’t matter.

Unlike in Houston, where he watched Points make a putt to win, it was Horschel who made the winner this time.

Horschel rolled in the long birdie putt to finish his week at 20 under and secure the win.

Overnight leader Lucas Glover, meanwhile, never got any momentum on Sunday.

He parred each of his first five holes before the horn sounded for dangerous weather in the area.

After a three-hour delay, Glover returned to the course only to bogey his next hole. He never challenged the lead again, shooting a 71 to finish five back.

The final round has resumed at the Zurich Classic of New Orleans, where play was halted for a second time just after 5:30 p.m. ET.

Billy Horschel has a one-shot lead over D.A. Points as the two play the 18th hole.

Horschel is looking for his first career win.

Leader Billy Horschel will have to wait to his approach shot at the 18th hole.

The horn has sounded, signaling dangerous weather in the area. Play was suspended at 5:35 p.m. ET and players were brought in off the golf course.

While it was initially expected the delay would last perhaps 20 to 30 minutes, it appears that storm cells are building. Play is not expected to resume until at least 7 p.m. ET.

CBS' coverage, meanwhile, has switched to Golf Channel.

AVONDALE, La. -- TPC Louisiana seems to bring out the best in Aaron Watkins.

The 30-year-old journeyman guaranteed himself his best payday on the PGA TOUR this season with a final-round 65 and 13-under finish Sunday at the rain-soaked Zurich Classic of New Orleans.

Watkins' best previous finish on TOUR came in the 2009 Zurich Classic when he finished T7 and won $203,175.

He had missed the cut in five of six events this season with his only payout coming at the Puerto Rico Open presented by seepuertorico.com when he tied for 30th.

"My scores didn't show it,'' Watkins said. "But I felt it was right around the corner. It's just a matter of getting some putts to drop. I felt like I've been hitting the ball well, just not scoring that well.''

Watkins' bogey-free round featured seven birdies, including a 20-footer on the 191-yard, par-3 ninth, his finishing hole.

"That was big,'' he said. "I putted good all day today. It was nice to see 'em fall. I gave myself opportunities and took advantage of them and got one on the last.''

Unaccustomed to being in the top 10 in a TOUR event, Watkins said he felt some angst on his finishing holes.

"I kind of got a little nervous because I saw myself getting a little closer to the lead,'' he said. "But then (Billy) Horschel took off. Hopefully, my score stays where it is. But I got a feeling with the course playing as soft as it is with lift, clean and place, the guys are going to continue making birdies.

"But regardless where I finish or how much money I make here, the way I've been playing and to play like I did this week, it shows my game is moving in the right direction. It's nice to see it all come together.''

In the final round of the 2013 Zurich Classic of New Orleans, we take a closer look at Jimmy Walker’s swing off the tee on the 372 yard, par-4 eighth hole.

Billy Horschel leads by two at the Zurich Classic of New Orleans, where he's six holes away from his first career victory.

With his sixth straight birdie (on No. 12), Horschel has also matched the longest streak on the PGA TOUR this season. The record for most birdies in a row is nine, set a couple of years ago at the RBC Canadian Open.

Horschel came into this week 108th in final-round scoring average. So far, he is tied with the lowest round of the day so far (Arron Watkins is already in with a 7-under 65) and hasn't missed a green in regulation.

Meanwhile, D.A. Points has done well to keep pace, playing his first dozen holes in 5 under. But every time he's birdied, so has Horschel.

Lucas Glover is alone in third, four off the lead, while four others are five back.

The final groups are on the back nine at TPC Louisiana, where Billy Horschel now has a two-stroke lead after his fourth straight birdie and fifth in the last six holes.

D.A. Points is alone in second.

A victory Sunday would be the first in the career of Horschel, who seems to have turned a corner in his career.

After being sidelined by a wrist injury in his first full year on the PGA TOUR in 2010, Horschel has finished in the top 10 in each of his last three starts. Two of those were top-three finishes for the former University of Florida product.

Meanwhile, three others, including Jimmy Walker, also looking for his first win, are three shots back.

Jimmy Walker makes a 27-foot putt for eagle on the par-5 seventh hole.
