Johnson leads, Woods lurking, everyone trying to cope with perilous test at sunny Muirfield

GULLANE, Scotland – Another sunny day along the Scottish coast. Another perilous test on the links of Muirfield.

Zach Johnson heads into the second round of the British Open with a one-shot lead Friday, the first time he's been atop the leaderboard at any major since he rallied to win the Masters six years ago. He opened with a 5-under 66.

The weather has been unseasonably warm and dry, the fearsome wind not much more than a gentle breeze. It's expected to stay that way through the weekend. Even so, there weren't many chances for going low, not on a course that is more brown than green, with pin conditions that some players complained were downright unfair.

First-round surprise Mark O'Meara has tumbled off the leaderboard after making two bogeys and a double-bogey.
