Stuard never bogeyed a hole throughout the tournament on the long (7,425-yard), par-72 TPC Louisiana course, which was drenched with more than 4½ inches of rain during the tournament. Weather delays on Thursday, Saturday and Sunday not only forced a Monday finish but also led officials to shorten the tournament to 54 holes.
Lovemark, Stuard and Byeong-Hun An entered the playoff at 15 under par.
An unraveled on the first playoff hole and Lovemark on the second while Stuard remained steady, virtually clinching the win with a 160-yard approach to within 2½ of the pin for an easy birdie putt.
Stuard is the seventh first-time winner at the New Orleans-area Tour stop in the past 11 years.
