Since his Masters win Rory has been in terrible form, so with Oakmont considered by many to be the toughest of the US Open courses, it's not looking too good for him. He will probably either miss the cut by miles or end up winning his 2nd major of the year.
Obviously Scheffler is the favourite 11/4, DeChambeau 7, Rory 14, Adberg 16, Schauffle 20, Morikawa and Niemann 25 and Lowry 30.
