DES MOINES, Iowa (AP) -- Duffy Waldorf shot a 5-under 67 on Saturday to take a one-stroke lead after the second round of the Champions Tour's Principal Charity Classic.
Waldorf had an 8-under 136 total. Bart Bryant and Jay Don Blake were tied for second. Bryant had a 64, and Blake shot a 66. Russ Cochran was 6 under after a 67.
The 50-year-old Waldorf is winless in 12 career starts on the 50-and-over tour after winning four times on the PGA Tour. He took advantage of calm conditions at the Wakonda Club to post a bogey-free round after opening with a 69 for a share of the first-round lead.
Jay Haas, a three-time winner in the event, was 3 under after a 70. Points leader Bernhard Langer shot a 75 to drop 11 strokes back.
