Billy Horschel and Scott Piercy won the Zurich Classic team event Sunday, closing with a bogey-free 5-under 67 in alternate-shot play.
Horschel became a two-time winner at TPC Louisiana. He captured his maiden PGA Tour triumph at the 2013 Zurich Classic when it was a traditional every-man-for-himself event.
Horschel and Piercy surged into the lead with birdies on the 10th and 11th holes. They followed that with seven pars to hold off Jason Dufner and Pat Perez by a stroke. Dufner had a 14-foot putt for the tie on 18, but left it a foot short.
This was the second year of the Zurich's switch to a two-player team format.
The victory was Horschel's fifth and Piercy's fourth.

Adrian Otaegui of Spain, who had moved into a share of the third-round lead with England's Matt Wallace after shooting 67 on Saturday, matched that score on Sunday to finish in second. Wallace finished tied for third with two others after a 68, two strokes behind.
Lydia Ko wins at Lake Merced with playoff eagle
Lydia Ko hit a 3-wood to 3 feet for eagle to finish off Minjee Lee on the first hole of a playoff Sunday in the chilly LPGA MEDIHEAL Championship
Ko won her 15th LPGA Tour title and first since July 2016, a 43-event stretch marked by changes in instructors, caddies and equipment and a large weight loss. Five days after turning 21, the New Zealander won for the third time at Lake Merced after taking the Swinging Skirts LPGA at the tree-lined layout in 2014 and 2015.
Twenty yards behind Lee in the fairway on the par-5 18th in the playoff, Ko hit a soaring 3-wood that cleared the tree limbs on the right, landed in front of the green and rolled inches by on the right side.
Lee, the 21-year-old Australian who won the 2012 U.S. Girls' Junior winner at Lake Merced, hit her second shot into the rough near the right greenside bunker and made a 10-foot birdie putt.
Ko closed with a 1-under 71 to match Lee at 12-under 276. Lee had a 68.
