'I'm delighted to win,' said McNulty, who pocketed $240,000 for the victory. 'I have been playing well and had my chances this year. I would not miss this tournament again.'
The first playoff hole was the par-5 18th at Nashawtuc Country Club. Pooley made a mess of the hole from the start as he drove into a fairway bunker and was forced to pitch down the fairway. The others drove into the short grass, but had problems with their second shots.
McNulty's second came up short and right in a bunker. Purtzer nailed his approach over the green in the rough. Pooley knocked his third to the back fringe, so it was down to a short-game contest.
Neither Pooley, nor McNulty hit good shots as McNulty's blast from the bunker never reached the putting surface. Pooley pitched his fourth to the front fringe. McNulty hit a good fourth and tapped in for par. When Pooley's chip did not fall in the cup, he was eliminated.
Purtzer had the advantage as his third stopped 7 feet from the flag. He missed the birdie putt, but tapped in for par and headed with McNulty to the 17th for their second playoff hole.
Mother Nature intervened on another hot day at Nashawtuc Country Club. Lightning was spotted in the area, so officials took the pair off the course for about an hour.
When the duo came back out, McNulty hit a 7-iron to 20 feet. Purtzer used the same club, but was 5 feet closer. McNulty drained his birdie putt, and Purtzer missed his, giving the title to McNulty.
'There's no better feeling than going to the 17th hole after an hour break and hitting a cut 7-iron close to the pin,' said McNulty, who collected his first win of the year and fourth in less than two full years on tour. 'I always felt it would be close and I'd need to do something at the last couple of holes.'
McNulty got into the playoff when he got up and down for par at the 17th in regulation. He landed in a bunker with his second at his 54th hole, but blasted inside 3 feet to set up birdie.
For Purtzer, it will be more unanswered questions. He was tied at 12 under when he played 17, but hit an awful chip and walked off with bogey to fall one back. He rolled in a 3-footer at 18 to get into the playoff.
Purtzer held the 36-hole lead last year until Craig Stadler blew by him in the final round.
'My short game let me down again,' admitted Purtzer. 'I don't make putts like I need to. It just didn't happen today. One of these days something good will happen here.'
D.A. Weibring (69), Bruce Lietzke (69) and John Bland (70) shared fourth place at 9-under-par 207.
Hale Irwin (70), Jerry Pate (71), Des Smyth (66), David Eger (69) and first- round leader Leonard Thompson (71) tied for seventh place at 8-under-par 208.
Stadler finished in a tie 12th at minus-7 after a final-round 69. The tour's leading money winner, Dana Quigley, also tied for 12th thanks to a 59 on Sunday.
