'This is the best,' said Doyle, who collected $225,000 for the victory. 'I just can't put it any better than this. I still consider myself a New Englander.'
Doyle, who was born in Rhode Island, picked up his first win in 2003 and became the 19th different winner in 20 events on the Champions Tour so far this year. The win was Doyle's eighth since joining the elder circuit in 1998.
D.A. Weibring (65) and Tom Purtzer (67) shared fourth place at 11-under-par 202.
Doyle charged into the lead Saturday with an 18-hole-tournament-record 63 and began Sunday's final round with a two-stroke lead. He added a birdie at the par-4 third when he knocked a 9-iron to 25 feet and rolled home the putt.
Doyle essentially put the tournament out of reach for the rest of the field at the par-5 fifth at Nashawtuc Country Club. He played a 3-wood to two feet and tapped in for eagle to get to 14-under par.
'I felt really comfortable after the eagle,' said Doyle.
Doyle birdied the par-3 eighth hole when he drained a 25-footer and from there Doyle hung on with pars until thunderstorms hit. For the third day in a row, storms caused a suspension of play, this time for over 90 minutes and when Doyle was on the 15th hole.
'I was not too thrilled about the rain delay,' said Doyle. 'I don't like playing conservatively as I did down the stretch. It felt like I might try too hard.'
Doyle came back to the course with a three-shot lead and did nothing to lose it. He parred the final three holes and cruised into the clubhouse with the win.
'I show up each week and think I can win,' said Doyle. 'I've got a good year going now.'
Doyle may have only picked up his first win of 2003 but he owned 11 top-10s heading into the event. The $225,000 first-place check moved him over the $1 million mark for the fifth consecutive year.
Fleisher mounted the closest charge to Doyle Sunday and reached 13-under par thanks to six birdies in his first 14 holes. He hit a poor chip at the 15th and bogeyed the hole to fall into the tie for second.
'I got within two but hit the wall at No. 15,' said Fleisher, who carded a 5-under-par 66. 'Number 15 was the turning point. It's great for the tournament with Allen winning.'
Gilder birdied three holes in a row after a bogey at nine. He had a pair of 12-foot birdie putts at 16 and 17 but neither found the bottom of the cup and left with a 3-under 68.
'I was struggling all week but I'm very happy finishing second,' said Gilder. 'I put some pressure on him on 10, 11 and 12 but couldn't do anything after that.'
Doug Tewell and Ed Fiori carded matching rounds of 68 to tie for sixth place at minus-10. Jay Sigel and Morris Hatalsky shot 66s to join James Mason (71) in eighth at 9-under-par 204.
