World No. 3 Jason Day will return to action this week at the BMW Championship as the FedEx Cup Playoffs heads at Conway Farm golf club. Despite leading the overall standings ahead of the season finale tournament, Day is expected to have a close fight with World No. 2 Jordan Spieth in the early group round. But Day appears to be the favourite to win the third leg of the four-event tournament according to oddsmakers.

According to The Spread, oddsmakers from BetDSI gave Day an 11/2 odds to win the BMW Championship. Day is followed by Rory McIlroy at 15/2, Jordan Spieth at 10/1, and Henrik Stenson at 11/1.

CBS Sports also reported that Day is the favourite to win in Lake Forest based on the odds of Westgate Las Vegas Superbook. The report stated that Day is at 2-1 to win the tournament this week, while Spieth lurks behind at 3-1.

Day, who won this year’s US PGA Championship at Whistling Straits earlier last month, will have a tight competition in the early round of the BMW Championship. For the third event in a row, FedEx Cup leaders Day and Spieth will spend some time together, along with Rickie Fowler, who jumped to No. 3 in the FedEx Cup standings with his win at the Deutsche Bank Championship.

Day enters the leader in the points race after his victory three weeks ago at The Barclays, and will have the chance to climb atop the leaderboard of the world golf rankings for the first time with a win this week. Spieth, who has been World No. 1 for a couple of weeks, said there is no reason for the Australian golfer not to be at the No.1 spot.

"There's no reason why he shouldn't (be No. 1)," Spieth told the Chicago Tribune. "He's been the best player in the last month or last couple months, going back to really the end of the (British) Open."

Day had his chance of being world No. 1 at the Deutsche Bank Championship, but the 27-year-old Aussie failed to capitalize after playing poor in Boston. However, Day believes he is the “guy to beat“ if he could get the mentality he had when he won his first major title.

"That's the mentality I have to get to all the time," Day said, reports ABC News. "And I think once I get to that, then I'll be a lot more consistent."
