Golfer's excruciating hole-in-one near miss

American golfer Ryan Armour will be cursing his bad fortune after missing out on one of the greatest shots of his life by the narrowest of margins.

The 41-year-old hit a stunning tee shot at the par-three 17th during the opening round of the Pebble Beach Pro Am.

Armour's sumptuous shot hit the green, caught a slope and started tracking right for the cup.

But in a cruel twist of fate, the ball flirted with the outside edge of the hole before coming to rest agonising close to the cup.

A small consolation for Armour came in the form of the easiest birdie he'll ever make to move into the top half of the leaderboard at one-under par.

The American then grabbed another birdie on the last to sign off with a round of 70.

Coming off a win in his last US PGA Tour start at Torrey Pines, the Australian world No.10 carded a three-under-par 69 on the Spyglass Hill course in California.

Former world No.1 Day mixed five birdies with two bogeys to leave himself four shots off joint-leaders Kevin Streelman and Beau Hossler.

World No.1 Dustin Johnson got his tournament off to a flyer with a 67 at Spyglass Hill placing him at five under.

Defending champion Jordan a Spieth shot an even-par 72.
