He’s three shots off Jimmy Walker’s first round lead but Jason Day is the man the bookmakers fear at the PGA Championship.
They couldn’t split the Australian, Rory McIlroy and Dustin Johnson prior to the final Major of the year – the trio all locked together at 7/1.
But the struggles of the latter two, and Day’s solid opening 68, has seen him edge out in front and a new challenger take up the fight.
Day is as short as 9/2 to defend the Wanamaker Trophy and it is the Open champion Henrik Stenson who is considered his nearest challenger.
The Swede picked up where he left off at Royal Troon, a first round 67 installing him as second favourite at a general odds of 11/2 and a best priced 13/2.
Martin Kaymer already has a PGA Championship win in his locker and it is six years since the German lifted the trophy.
He’s been edging back into form in recent weeks and a superb 66 sees him just one adrift of Walker at the top of the leaderboard.
That consistency means prices as big as 11/1 in the odds charts may be tempting to some as could the 16/1 on Rickie Fowler.
The American cast aside some recent poor form with an opening 68 that has him installed in the top 10. Is it his time to finally pick up a Major in a year that has already seen three first time winners?
McIlroy’s four over 74 means you can get odds of 45/1 on him performing a miracle recovery while US Open champion Johnson, thanks to his seven over 77, is as big as 66/1 in places.
