SOUTHPORT, England — Bernhard Langer seized a three-shot lead after the third round of the Senior British Open on Saturday, mastering Royal Birkdale with superb links play for a 4-under 66.

Langer shared the overnight lead with American Mark Wiebe but birdied three of his first seven holes to jump in front on his own. David Frost of South Africa shot his third straight 68 to sit alone in second place, while Wiebe only managed a 70 to drop into third, four shots back.

Langer says "that was as good as I can play. My ball striking was almost perfect and I played really well."
