England's Nick Job survived a late challenge from close friend and adversary Carl Mason to win his first tournament of the year - the Weston Homes PGA International Seniors at Stoke by Nayland.
It was Job's fifth European Seniors Tour title and his first success since victory in The Gloria Classic in May 2007.
The 59-year-old, who was co-leader after day and outright leader by three shots going into the final round, secured his first wire-to-wire victory with a final round 69 to finish on 14 under 202 for the tournament - two clear of Mason.
Mason had closed to within one shot going into the final hole of the tournament, but a birdie from Job on the last sealed the win.
"It's a great win to beat to Carl and to finish with a birdie at the last on such a tough hole is only a pleasure," said Job, who collected a cheque for £26,250.
"He was creeping up and once that long putter starts rolling puts in you can't stop him, so I got very lucky.
"The last couple of holes were playing tough with the wind so you were under the cosh all the time, not only because of Mase but because of the course.
"The final hole is one that brings all sorts of worries and we were waiting quite a long time, so it was a bit scary.
"But it's lovely to win wire-to-wire, which I think is the first time I've done it.
"The course was in brilliant condition and these have to be the best greens in the world. So much so I'm want to take them home with me.
"I'm looking forward to coming back next year as every time I've won, we've never gone back to the place again."
Job, who had the luxury of opening up a three-shot lead on the final hole of day but instantly surrendered some his advantage with a bogey at the first after an errant tee shot.
However, he recovered from the glitch with back-to-back birdies and even stretched his lead to five shots before Mason started to haul himself back into the tournament on the back nine to put himself in the frame by the final hole.
Mason, carded his third sucessive 68 of the week and earned £17,500, was more than gracious in defeat but was pleased to have made Job sweat for the title.
"I'm glad I came at him at the close," he said.
"I was disappointed with my front nine, I was hitting the ball that well and hanging on at that point. But I hit some good shots, got some birdies and an eagle at the 16th to give Nick a good run for his money. I didn't want him to have it easy.
"I was five behind at one point, so I'm pleased came through, despite not playing the way I would like."
Scotland's Bill Longmuir, who began the week contemplating pulling out with a bad back, fired a third successive 69 to finish third on nine-under par 209 and earn £12,250.
The tournament also saw a sighting of that very rare bird - an albatross - England's Tony Charnley down in two at the 553-yard par five 14th.
