Colin Montgomerie took the third-round lead Saturday in the Senior PGA Championship, making a winding, 30-foot birdie putt on the final hole for a 3-under 68.

Trying to win his first major championship, the 51-year-old Scot took a 7-under 206 total into the final round at Harbor Shores.

Bernhard Langer, the 56-year-old German star who has won twice this season on the Champions Tour, was a stroke back after a 70. He will play alongside Montgomerie for the fourth consecutive round Sunday.

Marco Dawson, Bart Bryant and Kiyoshi Murota were tied for third at 5 under. Dawson had a 64, the best round of the tournament. Bryant and Murota shot 70.
