After making an impressive start to the year and finding himself in a tie for the lead with 18 holes remaining at the AT&T Pebble Beach Pro-Am, you could be forgiven for putting a house on world-number-one Dustin Johnson walking to another title.

A substandard final round, though, was not what Johnson was after as he could only manage a tied second finish, three shots off Ted Potter Jr’s winning total.

DJ began 2018 by bolding claiming he could win up to 10 times on tour this season.

He walked-the-walk immediately by winning the Sentry Tournament of Champions by an unassailable eight-shots.

That was followed up by a respectable tied ninth at the Abu Dhabi HSBC Championship despite being far from top gear.

The world-number-one looked to continue his impressive start to the 2018 campaign with a start at the AT&T Pebble Beach Pro-Am this week.

An opening five-under 67 put Johnson into a heaped tie for sixth before a second-round of 64 shot him into a tie for the halfway lead at 12-under.

A slower 70 on moving day was enough for Johnson to ensure he still took a share for the lead, now at 14-under, with Potter Jr into the final round at Pebble Beach.

Johnson failed to get moving early during the final round, the story of his entire round really, as he matched every front-nine birdie with a bogey to go out in a level-par 36.

In that time, despite an opening hole bogey, Potter Jr carded four birdies between the second and the seventh holes to move into an outright three-shot lead.

Johnson’s back-nine was no improvement with a birdie on the 13th sandwiched between two bogeys before a finishing birdie as the American slipped down the leaderboard to a final position of tied second at 14-under, as Potter Jr strolled to three-shot victory with a bogeyless back nine.

Given his promising position heading into the final round in California, Johnson may be disappointed to have faltered as he did on Sunday but a tied second added to his win and tied ninth so far this season is certainly enough to back up his brazen affirmation at the year ahead.
