Open Championship: Mickelson stays on top despite Scotland's foul weather

Phil Mickelson followed up his major championship record-tying round with a 2-under 69 on Friday for an early one-stroke lead in the 145th Open Championship at Royal Troon Golf Club in South Ayrshire, Scotland.

In blustery, rainy conditions, Mickelson controlled his game and scrambled to get to 10-under 132 midway through the British Open to lead Henrik Stenson, who shot a 65.

Keegan Bradley and Soren Kjeldsen are tied for third and three shots off the lead after each shot a 68. They are two strokes ahead of defending champion Zach Johnson, who bogeyed the last hole for a 70.

The 46-year-old Mickelson fired an 8-under 63 on Thursday in the opening round, coming within a lipped-out birdie putt on the final hole for a major championship scoring record.

Mickelson heads to the weekend trying to become the oldest Open champion since Tom Morris in 1867. Mickelson turned 46 last month and Morris was 46 years and 102 days old when he won at nearby Prestwick 149 years ago.

Mickelson, who got a break on the front nine before the steady rain came and made difficult conditions for players, birdied three of the first eight holes, including a near ace at the par-3 eighth.

On the back nine as rain came down harder, Mickelson made his first bogey of the tournament at the 12th, birdied the 14th and made bogey at the 15th.

Mickelson, a five-time major champion and 42-time winner on the PGA Tour, has not won since the 2013 Open at Muirfield.

"It's a lot easier having already held it," Mickelson said. "Winning the Open was the greatest challenge of my career, and I've already done it. I would love nothing more than to add another one. But knowing I've already done it takes the pressure off."
