Michael Allen shot a 2-under 69 for a share of the second-round lead with Fred Couples and David Frost on Friday in the Champions Tour's season-ending Charles Schwab Championship.
Second in the event last year, Allen saved par on the final hole after hitting his approach shot between the grandstands surrounding the green. He was given a free drop, chipped to 8 feet and made the putt.
Couples, tied for the first-round lead with Jay Haas after a 68, rallied for a 70 after a double bogey on the opening hole. Frost had a 69 to match Couples and Allen at 4 under at TPC Harding Park.
Mark Calcavecchia, Jay Don Blake, Bernhard Langer and Kenny Perry were a stroke back. Calcavecchia, Blake and Langer had 68s, and Perry shot a 69. Haas was 2 under after a 72.
Charles Schwab Cup points leader Tom Lehman had a 72 to fall four strokes behind the leaders.
Allen hasn't won on the tour since the Senior PGA Championship in May 2009 - the first tournament he played in on the 50-and-over circuit...
