Jason Day’s push towards a maiden major title has been thwarted by a cold putter midway through the final round of the US PGA Championship at Valhalla Golf Club.

In wet conditions after an earlier rain delay, Day had countless chances to push towards the lead but instead sits four shots off the pace.

Day is even through the opening nine holes of the final round to be 10 under for the tournament, now four shots back from American Rickie Fowler (eight holes) and Swede Henrik Stenson (nine holes) who lead at 14 under.

Phil Mickelson holds third spot just a shot behind at 13 under through eight with world No.1 Rory McIlroy fourth at 12 under through seven.

Five different players have already held a share of the lead on a wild Sunday.

It was a front nine of crucial misses on the greens for Day as he missed three birdie putts inside 11 feet and also a four-foot par putt.

Combined with a butchered bogey on the par-five seventh the 26-year-old faces an uphill battle to claim the Wanamaker trophy.

If not for making birdies on the fifth and eighth holes the Queenslander would be out of contention.

Day has struggled with his putter all week and could have easily been comfortably in the drivers seat had he been able to bury countless short chances.

He missed from 11 feet for birdie on the first and third holes and couldn’t knock in one from nine feet on the fourth hole before missing the short-par chance on the sixth.

Adam Scott’s dreams of making a big push died on the opening hole when he missed the fairway right and the green long, failing to get up and down and making bogey.

While he grabbed birdies on seven and eight he is still six back at eight under through 11 holes.

Matt Jones and Geoff Ogilvy finished up their tournament with a round of 71 to be one under for the week, while Marc Leishman (69) posted his first under-par round of the week to join his countrymen in a tie for 47th.
