A Georgia resident who grew up in nearby Norwood, Mass., and attended high school in West Roxbury, Doyle recorded his eighth win since joining golf's elder circuit in 1998. He shot a 4-under 67 for a 54-hole total of 15-under 198.
Fleisher, the first-round leader, made up a stroke with a 5-under but failed in a bid for his second win of the season. Gilder carded a final-round 68.
Another shot back were D.A. Weibring and Tom Purtzer.
Under a new format this year, former Edmonton Oilers goaltender Grant Fuhr captured the NHL Drive Fore the Goal. Three months before being enshrined in the Hockey Hall of Fame, Fuhr shot a 7-over 78 to win by two shots.
