CONCORD, Massachusetts (Ticker) -- Bob Gilder is getting the hang of this playoff thing.

Gilder won a Senior PGA Tour event in a playoff for the second straight week, tapping in a birdie putt on the third extra hole Sunday to defeat John Mahaffey and claim the FleetBoston Classic.

Last week, Gilder won the SBC Senior Open by beating Hale Irwin -- the best player on the tour -- on the first playoff hole. On Sunday, it took him two holes longer to dispatch Mahaffey, who caught Gilder with a final-round 65.

The duo played evenly through the par-5 18th and par-3 17th before returning to the 18th. Gilder's second shot landed scant feet from the green, while Mahaffey still needed more than 100 yards to the hole.

Mahaffey reached the green, but his ball settled below the pin, leaving a 30-foot birdie attempt. Gilder executed a perfect pitch-and-run that stopped 18 inches from the cup.

After Mahaffey just missed his long putt, Gilder tapped in to claim the $225,000 first prize.

Gilder held or shared the lead after each trip over Nashawtuc Country Club. However, he was a bit lucky Sunday, when a 2-under 70 left him with a 54-hole total of 13-under 203.

"I missed a lot of putts, but I made a couple I needed to make," he said.

Jim Thorpe missed a pair of putts on the final hole of regulation that cost him the tournament. With a chance to win outright, he rolled a seven-footer too fast past the cup, then missed the comeback three-footer for a bogey that dropped him to 70-214.
