SOUTHPORT, England -- Mark Wiebe of the United States shot a 5-under 65 Friday to share the lead with
Wiebe had four birdies on the back nine. Langer, the 2010 champion at Carnoustie, shot a 67 and made five birdies. Both players finished at 5-under 135.
"I really got my irons zoned in on the back nine," Wiebe said. "I know there's a long way to go, but I'm tickled to be where I am. It was unbelievable and great to shoot the low round."
Wiebe moved to 1 under by the turn with two birdies and a bogey. He had three birdies in four holes from the 13th and added another with a 15-foot putt at the last.
The German dropped two strokes at No. 6 when he double-hit the ball.
"The ball was sitting up in the long grass and I caught it high on the clubface and again on the follow through," said Langer, a two-time Masters champion. "But that was my only blemish. Most of it was impressive and good, and I putted a little better today."
"It was a bit of a shaky round," Frost said. "I didn't feel comfortable with the club in my hand. I hit some wayward shots, but managed to hit good irons into the greens and the putter was my savior."
Overnight leader Gene Sauers shot a 70 for a share of fourth place with
