More accessible flag positions and tees brought forward in key areas had the golf course set up for excellent scoring and so it would prove. 23 players broke par on day three but do not be surprised if the USGA revert back to the set-up of earlier days and tomorrow's golf course will be a much tougher proposition.
Jason Day was the big mover, and in the right direction, his stunning round of 65 moving him his overnight score of 1 over and 25th position to share second position with Lee Westwood as he walked from the course. He would eventually finish the day in a share of third with Lee Westwood with whom he will play tomorrow.
Day took a while to get things moving but when he did there was no stopping him. He found the green at the par five 6th and two putted from 40 feet to get underway. He then hit a fine tee shot at the 7th to 12 feet for another birdie and one hole later he hit a delicate pitch from the right rough to a tight flag and holed from 4 feet.
At the 9th he had another great chance after a magnificent tee shot at the par five but his approach, while on line, was a little long and he was unable to get up and down from just off the green.
At the 10th, with the flag cut in the back of the green but the tee forward, Day all but holed his tee shot and made it from just behind the flag to move to 4 under for the day and 3 under for the tournament. He was in a share of 3rd at that stage but more was to come.
Importantly he handled the dangerous holes through the middle of the back nine,sometimes precariously, but he was able to pick up a birdie at the par five 16th, after being forced to play up,then another at the last when he holed from 35 feet for the closing birdie and his round of 65.
Day will play with Westwood in tomorrow's final round after it appeared at one stage as he might have been out in the final pairing with the leader. Yang's late recovery put an end to that but for the 23 year old it is but another great opportunity in front of a world stage.
John Senden recovered from a bogey at the first to be at 1 under for the tournament through twelve holes but then bogeyed three of his last six holes to be at 1 over.
Marc Leishman was frustrated with his ball striking but reached the turn in 2 under for the day and the tournament and at that point was right in the mix. Like Senden he struggled over the closing nine holes and he too is at 1 over and in a share of 27th position.
