Endycott had to sleep on the third-round lead for two nights after thunderstorms and water-logged courses forced a Monday finish.

But the 27-year-old held his nerve to convert a two-shot advantage into a four-stroke victory with a final-round three-under-par 67 at TPC Sawgrass' Dye's Valley Course.

With the top-five finishers and ties earning cards, Endycott secured his ticket back to the big time after he had finished 139th in the FedExCup standings in his rookie PGA Tour season.

The Q-school triumph was nothing but deserved after Endycott recorded just three bogeys in 72 holes this week to prevail at 16-under, well clear of American Trace Crowe at 11-under.

Blaine Hale Jr was third at nine-under, one shot ahead of American Hayden Springer and Mexican Raul Pereda, who shared fourth to wrap up the remaining PGA Tour cards.

Endycott's success vindicates the Sydneysider's decision to roll the dice and buy a house in Nashville recently despite his uncertain future.

He had been guaranteed status on the secondary Korn Ferry Tour but now has automatic entry to full-field PGA Tour events for 2024.

The 40 next best players and ties at Q-school earned Korn Ferry Tour cards but unfortunately fellow Australian John Lyras missed out by one shot.

Lyras closed with an even-par 70 at Sawgrass Country Club to tie for 54th at one-over.

It was a rough day also for countryman Tom Power-Horan, who started well positioned in a share of 24th but ended joint 64th at two over following a closing 74 at Sawgrass Country Club.
