With one great shot, Camilo Villegas turned a solid ground into his lowest start in more than a year.
Villegas drilled a 3-wood into 8 feet on the par-5 18th hole and made the eagle putt for a 6-under-par 64.
That gave him a one-shot lead over Rickie Fowler, Branden Grace, Graham DeLaet and Robert Streb after the first round of the Honda Classic.
Defending champion Rory McIlroy and Tiger Woods each shot even-par 70 and walked off PGA National with different emotions. Woods was thrilled it wasn't worse. McIlroy was disappointed it wasn't better.
Villegas lost his card last year and is playing on sponsor exemptions.
