Danny Willet made a strong start on the second day of the Open today as the contest on the old course at St Andrews heats up amid scattered showers leaving him -10 after 11 holes.

On the 12th hole, a deceptively difficult short par 4, Willett gained another birdie putt from roughly 35ft. It was a great hit but left him short for a gimme par.

For quality player Zach Johnson, though, it became clear that he was not on his A-game and a was instead a little frustrated, which became apparent when he hit 12 feet passed a hole on one occasion - though he had started to recover by the halfway mark.

Lots of long-range putts appeared to be falling short on day 2. Justin Rose fell to this theme on the 6th when failing to strike hard enough for a birdie.

Phil Mickelson meanwhile, who has previously won a Masters title, got his wood out on the fairway on the par-five fifth, hitting a great second shot.

After the opening day yesterday, Dustin Johnson finished by posting a seven-under-par 65, leaving him ahead of the pack, which included Scotland's 1999 Open champion Paul Lawrie, and England's Danny Willett by one shot.

He also left ahead of his playing partner, American Jordan Spieth on day one, gaining a subtle revenge after last month's US Open, where Johnson finished second behind Spieth.

Master's winner Spieth, the odds on favourite to win the Open title, carded 67, so was two shots off the lead as he continues in his quest for the grand slam.

“Nothing bad happened at Chambers Bay, so I wasn’t disappointed, really,” Johnson insisted. “I played really well, did everything I was supposed to. I couldn’t control what the ball was doing on the greens there.

Jordan Spieth continued “There’s really no bad feelings from that, only good. I played really well and then it carried over to today. I played really well today.”

Three times champ Tiger Woods has so far put in a miserable performance.

Does Johnson have scar tissue from Chambers Bay exit?

It will take until Johnson is on the 72nd green again and in position to win a major championship to determine whether mental scar tissue from Chambers Bay exists. 

Johnson opened with only the third bogey-free round of his major career, which he has never bettered 65 in a major tournament.
