Bernhard Langer rode a putting streak to a second 65 and a two-stroke lead over Wayne Levi after yesterday's second round of the $700,000 Sammy Davis Jr.-Greater Hartford Open golf tournament in Cromwell, Conn.

The West German birdied four of his last five holes to pull ahead at 12-under-par 130 after two rounds over the par-71, 6,786-yard Tournament Players Club of Connecticut.

Langer, who has six top-10 finishes in the United States this year, made a 60-foot putt for a birdie on the par-3 fifth hole, his 14th hole of the day. Then, after scrambling for par on the sixth hole, Langer finished his round with three birdies.

Levi, who shot a 7-under 64 to lead the opening round, started in the afternoon when a steady rain hampered playing conditions. He managed a 68, including birdies on three of his final four holes.

Tom Watson shot a 68 for 135.
