Langer leaders in Pittsburgh

Bernhard Langer hit a sparkling six-under-par 64 to take a stranglehold of the Senior Players Championship at Fox Chapel Golf Club in Pittsburgh.

The German two-time Masters champion eagled the par four seventh and added five more birdies against just one bogey to record a two-round total of 129 - 11-under for the tournament.

His round was enough to give 56-year-old Langer a two-shot lead over the field as he chases his third major title on the Champions Tour for the over-50s.

Langer leads American duo Bill Glasson and Doug Garwood by two after they shot 64 and 67 respectively to move to nine-under.

With ideal scoring conditions in Pennsylvania, Langer's only major problem in the round on the final hole when he broke his driver after teeing off at the par-five closer.

"I hit a good tee shot and as I picked up my tee, I heard it rattle in my driver head," Langer said. "And I'm going, 'Wow, what's that rattling for?'

"Then I grabbed the head, and it was loose. Something broke inside the screw that holds the shaft in. I have to go and see the tour rep down there or the guy that repairs the clubs and see if he can fix that one or I have to go to my backup driver."

Americans Joe Durant, John Riegger and Michael Allen join Ireland's Mark McNulty (66) a shot further back on eight-under, with defending champion Kenny Perry just one stroke behind after a sparkling 63, playing alongside Langer.

"I saw Kenny Perry go low so I figured if him and I go low, there's going to be others that could go low too," Langer added. "So I am trying to keep making the best shots I can and make more birdies."

Perry won his first senior major in last year's event, but knows it will be tough to reel in Langer over the weekend.

"I don't know if they're going to be able to fix that driver so it may give us a shot," Perry joked. "(Langer's) playing flawless golf. The only reason he made bogey on that 14th hole, he had a mud ball that shot it way left of the green.

"He's hitting it perfect, so he's going to be a hard man to catch. I'm going to have to keep shooting 63s to catch him."

Senior PGA Championship winner Colin Montgomerie is nine shots behind after a second round 69.
