GULLANE, Scotland (AP) - Zach Johnson took advantage of early conditions conducive to low scores by shooting a 5-under 66 in the opening round of the British Open at Muirfield. Overall scores in the morning were much better than the ones in the afternoon when the course dried out.
Johnson holds a one-shot lead over 56-year old former British Open champ Mark O'Meara and Spain's Rafael Cabrera-Bello.
Tom Lehman, Dustin Johnson and Brandt Snedeker are in a group two shots back.
Tiger Woods was one of the few that weren't adversely affected by playing later in the day. The three-time champ shot a 2-under 69 to join a group that includes Phil Mickelson and 19-year old Jordan Spieth (speeth) who qualified for the major after scoring his first PGA Tour win last week in the John Deere Classic.
In other scores of note, defending champion Ernie Els shot a 74, Bubba Watson opened with a 70, Tom Watson and Fred Couples shot 75's, and Nick Faldo and Rory McIlroy finished with 79's.
