Smith enters the BMW Championship starting on Thursday in third spot in the race for the $US15 million jackpot awarded to the season-long FedExCup champion.

"I don't know, I'm pretty set, to be honest," the Australian men’s No.1 said when asked what he'd do with such riches.

"I'm good. I'm good with what I've got. I don't know what I'd do, to be honest. Maybe some more fishing equipment."

What Smith craves is the trophy after letting The Northern Trust honours slip through his fingers on Monday when he sliced his tee shot out of bounds on the first playoff hole, gifting victory to American Tony Finau.

"It's just added motivation," Smith said.

"Obviously in those situations you want to come out on top, and that's not always the case.

"Sometimes the guy just plays better, and I feel as though I kind of just let that one slip away, so it's a bit of a different feeling.

"Yeah, definitely more added motivation to try and sort this thing out."

Smith also drove into the trees while leading up the final hole at the WGC-FedEx St Jude Invitational two weeks ago, allowing Abraham Ancer to win a three-man playoff.

"I've been playing some really solid golf so I'm not really satisfied with how my year has gone. I feel as though I could have done so much more," he said.

"The last couple weeks especially, I've been very frustrated with my driver. It's always been kind of a weakness of my game. It's cost me a few runs at tournaments this year.

"I spent a bit of time on the range this morning hitting some drivers, trying to sort some stuff out.

"It's nothing too major. I don't need to go through a whole swing redo or anything.

"It's just a couple of technical things, and hopefully I can sort them out and have a couple nice runs at the last two events.

"I feel like my game is in a really good spot, and it's a good time of the year to have your game in a good spot."

With players grouped according to their FedExCup standings, Smith will tee off for the first two rounds at Caves Valley alongside series leader Finau and World No.1 Jon Rahm, who he out-duelled during Monday's delayed final round in New Jersey.

Fellow Australians Marc Leishman and Cam Davis, in 35th and 36th positions respectively, will play together alongside American Cameron Tringale.

Matt Jones, in 42nd spot, has been grouped with major winner Lucas Glover and Swede Alex Noren.

Only the top-30 in the standings will advance to the Tour Championship in Atlanta from September 2-5.
