Jason Day's lacklustre and turbulent PGA Tour season is over with the former World No.1 bundled out of the PGA Tour's finals series on Sunday.
The Australian star shot a two-over-par 74 to finish the BMW Championship at four under and he will not make the top 30 on the FedExCup standings who advance to the Tour Championship.
It will be the first time in seven years Day has missed the PGA Tour’s Playoffs finale in Atlanta, Georgia.
The 31-year-old cut a frustrated figure as he walked off Chicago's Medinah Country Club.
"It was just a very, very below average season," day told AAP on Sunday.
"It's been a while since I missed Tour Champs, so that's disappointing."
Day put together some solid results despite sacking three caddies and managing chronic back injuries.
The Queenslander finished in the top 10 in six of the 21 events he teed up in – including a tie for fifth at the Masters – while earning more than US$2.6 million in prize money.
But Day judges his seasons on wins and performance in golf's majors.
Day earned top-25 results at the US PGA Championship and US Open, but was never in contention in those events, while he missed the cut at The Open.
Even at the Masters, Day shared the 36-hole lead only to shoot himself out of contention with a poor third round.
Day failed to record a win this season after claiming two victories last season.
His frustration contributed to splitting with caddies Luke Reardon and Rika Batibasaga in June.

Day hired Tiger Woods' former caddie Steve Williams before the US Open but in six events the pair missed two cuts and recorded just one top 10.
Day slid out of the top 20 on the world rankings for the first time since mid-2013.
Adding insult to injury, he was unable to climb inside the top eight on the International team standings for the Presidents Cup which are finalised after the BMW.
He will now need a captain's pick from skipper Ernie Els to play the biennial teams event being held at Royal Melbourne in December.
Day vowed to take six weeks off and mentally refresh in an effort to start his quest back to World No.1 next season.
"I'm looking forward to having some time off; I need to get away from golf and regenerate everything and move on to next season," Day said.
Day confirmed close friend and fellow pro golfer David Lutterus would caddie for the remainder of the year.
"It went well; Dave did a great job and I putted a lot better and I struck the ball okay," he said.
"We're going to work for the rest of the year and we'll go from there."
