Half of the field have yet to start their second round but Dustin Johnson is the clear favourite with those who set the odds to break his Major duck.
The American’s hugely impressive first two rounds of 67 and 69 may only have him tied for the lead, but he is as short as 9/4 with some firms to take the title.
Impressed by the way Johnson has negotiated the tough Oakmont track, having hit 31 of 36 greens in regulation and averaging more than 318 yards off the tee, he is the runaway leader in the market.
Sergio Garcia 51-foot bomb on his final hole put him into tied 4th, just two shots off the pace of Johnson, but you get prices as big as 19/2 on the Spaniard maintaining his challenge right to the line.
The bookies are clearly expecting players to move backwards when some of the top contenders finally get their second rounds under way later today.
Lee Westwood’s opening 67 was hugely impressive but the Englishman can easily be backed at prices as big as 12/1.
They are the same odds as defending champion Jordan Spieth, who was five shots worse off following his opening effort.
Andrew Landry – who shocked everyone as a first round leader following his 66 – is considered an afterthought by those who set the markets.
You can find him at odds as large as 80/1, with 20 other players considered to be better bets.
A star of the European Tour who is being similarly dismissed by those in the know is Andy Sullivan.
The Englishman posted an impressive 68 and that lifted him to one under for the US Open and into tied 7th.
But if you look around you can find odds as big as 50/1 and that is a price that may well prove attractive.
With Oakmont in scoring form yesterday – the worst player in the top 72 to complete their second round came in with 72 – it will be interesting to see how many contenders drop away as the greens get faster throughout Saturday and Sunday.
Keep an eye, though, on Bubba Watson and Adam Scott. Both are very much in the frame but can be backed at double figure odds
