Playing with Reed in the final group on Saturday, Leishman struck the ball beautifully but a cold putter cruelled his chances at donning the green jacket this week.

World No.16 Leishman carded a one-over-par 73 to fall to six under and a distant eight shots off the pace.

Overnight leader Reed showed no signs of nerves atop the famous white and green leaderboards during a round of 67, which catapulted him to 14 under.

Leishman started moving day just two shots behind Reed and gave himself every chance, hitting 14 of 18 greens in regulation.

But a series of missed birdie putts from short range stalled his charge.

"I hit a lot of good putts; they just weren't going in ... it wasn't my day," Leishman said, settling for a share of sixth.

"That was pretty much the story of the day; I hit it well enough to shoot a really good score, but it just wasn't meant to be."

Queensland’s Cameron Smith was climbing the leaderboard and almost aced the par-3 16th, his tee shot leaving him a tap-in birdie.

But bogies on the 17th and 18th left the 24-year-old at three under after a 70.

"Yeah, it's pretty frustrating," Smith said.

"I feel as though I played really solid golf for 16 holes but the driver let me down those last two holes and put me in positions you really don't get away with."
