GULLANE, Scotland (AP) — Iowa native Zach Johnson takes a one-shot lead over 56-year old former British Open champ Mark O’Meara and Spain’s Rafael Cabrera-Bello into today’s (Friday’s) second round at the British Open at Muirfield. Tom Lehman, Dustin Johnson and Brandt Snedeker are in a group two shots back.

Three-time British Open champ Tiger Woods shot a 2-under 69 to join a group that includes Phil Mickelson and Jordan Spieth, the 19-year-old 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.
