Colin Montgomerie will go to the Open Championship on the back of a missed cut for the first time after crashing out of the Scottish Open.
Five days after victory at the European Open ended 19 months without a victory, Montgomerie hit a second-round 74 to finish on 143 along with Retief Goosen.
Gregory Havret of France and Spain's Jose Manuel Lara held the lead
Phil Mickelson was one stroke off the lead after a 68, with Ernie Els and Sergio Garcia hovering in the shadows.
Havret, one of the early starters, blitzed his way to a seven-under 64 for a 10-under total of 132 in perfect conditions.
Lara shrugged aside the heavy rain later in the day to shoot 65.
Els (66) was among four players on seven-under 135, with Garcia (65) among another group on 136.
Montgomerie finished at lunchtime, but it was 1900 BST before his exit from the event was confirmed.
He had resumed on two under par, only four off the lead, and was three under after seven holes before bogeys on the short 17th, first, third and fifth.
"I hit 27 out of 28 fairways but I just didn't putt well at all," he said.
