Glance at first round of British Open

A glance at Thursday's opening round of the British Open at 7,192-yard, par-71 Muirfield.

Leading: Zach Johnson, who made only one bogey en route to a 5-under 66.

Trailing: Mark O'Meara, who won this major championship in 1998, and Rafael Cabrera-Bello. Both shot 67.

Where's Tiger?: Woods was three shots back at 69.

Notable: A dozen players broke par in the morning tee-time groups, but only eight in the afternoon as unseasonably warm temperatures and sunshine produced faster, firmer conditions throughout the day.

Quotable: "Sometimes I feel like I'm walking out there and I'm unconscious." Rory McIlroy after shooting 79.

Television: Friday, ESPN, 4 a.m.-3 p.m. EDT.
