Impossible to call a winner
With everyone struggling with the conditions, this is a real lottery as to who will win the trophy.
This is thhe sort of finish every fan dreams of on a final round.
For the players, this could be the biggest three holes of their careers.
Four players sharing the spoils
After a bogey on fourteenth, J J Spaun is now back to +1.
He shares the lead with Burns, Hatton and MacIntyre.
The Scot has come from nowhere to get himself in the mix to potentially win the tournament.
And then there were three
With shots being dropped all over the place, Spau has just sent his second shot into the heavy rough.
He still has a one shot lead but plenty to do to save par.
Hatton has just played a brilliant approach to the fifteenth green with a chance for birdie.
He is in joint second on +1 with Burns currently.
American takes outright lead
J J Spaun has just sunk a monster putt for birdie on the thirteenth green.
He moves to even par and is the outright leader.
We can expect to see things change dramatically from one hole to the next on the run-in.
Conditions testing golfers
Nobody is finding it easy out there.
Ortiz found himself in the heavy rough and did well to get out in one shot and find the fairway.
Now it means an incredible approach shot is needed to keep his share of the lead.
Drama contiues at Oakmont
With the leaders only a hole apart, the action is fever-pitch.
Five players are all on +1 and par putts are being cheered like birdies.
It is so tight, one fantastic shot could decide the winner.
