DUSTIN JOHNSON and Rory McIlroy were among two stars to bite the dust on a dramatic day 2 at Baltusrol.
Tournament favourite Johnson's driven poorly and Rory's putted badly and that's cost the big guns.
First-round leader Jimmy Walker has been joined at the top on nine under by Robert Streb but it's Jason Day and Henrik Stenson who lead the betting.
World No.1 and defending champion Day, two off the pace, is 5-2 with Ladbrokes and McBookie despite writing himself off at the start of the tournament.
Open champion Stenson, who has fired two 67s, is 9-2 with most firms and that will please Ace Venturer who tipped him to win at 16-1 pre-tournament.
Walker is 7-1 with Ladbrokes and others and the big American shouldn't be written off while lesser known Streb is 12-1 at Ladbrokes.
My mythical twoballs saw just one of three yesterday but today we start proper twoballs and hopefully I'll fare better.
