TURNBERRY, Scotland (AP) -- Bernhard Langer fired a first-round, 6-under 64 on Thursday in his bid to add a second Senior British Open championship to the one he won at Carnoustie two years ago.
He picked up six birdies with putts of 12 feet, 15 feet, 18 feet and 16 feet at the par-4 second, third, 11th and 12th holes, and was on the two par-5s in two, and two-putted both from distance for birdies at Turnberry.
"I was very pleased with the way I played," said Langer, who is third in Charles Schwab Cup points. "Played smart. Hit some good drives, good iron shots and sank a few putts. Maybe left a couple of putts out there as well."
Zimbabwe-born McNulty, like Langer, played flawless golf with five birdies at the first, second and seventh on the way out and the 10th and 17th on the way home and no dropped shots.
Allen was having an impressive season on the Champions Tour, topping the money list with two wins this season. He's fourth in Schwab Cup points.
"I played beautiful on the front nine, made a few mistakes in the middle then had a great finish," said Allen, who eagled the par 5 17th and birdied the 18th to pick up three of his four strokes.
"Out here in a short-sleeved shirt in Scotland playing this wonderful course is as good as it gets," he said.
Lehman opened with a bogey 5 at the first but then bagged six birdies, including 2s at the short fourth and sixth holes, before dropping his only other shot with a bogey 5 at the 16th.
Mast was 3 under par after four holes, dropped one at the sixth before a birdie at the ninth took him to the turn in 32. He picked up two more birdies at the 11th and 14th, but then dropped strokes at 15 and 16 before a birdie at the last.
It was a similar story for Blake, who had three birdies on the way out and two on the way home dropping just one shot at the par-4 12th, while Frost picked up four strokes in three holes when he birdied No. 6, eagled 7an d birdied 8 to be out in 32.
"It was like a garden out there, a beautiful garden," Frost said. "Like playing in Hawaii."
Lu had no less than six 3s in a best-of-the-day first nine holes of 30. He birdied the opening three par 4s, parred the two par 3s, got his fourth birdie at the long seventh then yet another birdie 3 at the eighth.
He couldn't quite sustain it on the way home, dropping two shots and picking up just one more birdie.
Three players were at 67 and four more at 68, including American Loren Roberts, who won the Senior British Open the last time it was at Turnberry in 2006.
Tom Watson, bidding for his fourth Senior British title and his second at Turnberry, was in a large group at 69.
He started his round with eight straight pars, bagged two birdies round the turn then dropped just one shot at the 13th before parring his way home.
"The course is there for the taking on such a beautiful day and Bernhard did that. He's that good of a player and he's in good form," Watson said. "He and his caddie Terry really work out how the course should be played. That's why he's so successful."
