England's Simon Dyson credited "constant nagging" for taking his career to the next level after claiming his second European Tour title of the season in the KLM Open.
Dyson beat Australian Richard Green at the first hole of a play-off after the pair had finished tied on 14 under par here at Kennemer GC.
The 28-year-old from York rolled in a 10ft birdie putt to claim the £180,000 first prize after Green failed to hole his birdie attempt from long range.
Ireland's Damien McGrane, who took a three-shot lead into the final round, carded a 70 to miss out on the play-off by a shot in third place.
France's Christian Cevaer took fourth on 12-under with Wales' Garry Houston another stroke back in fifth. Colin Montgomerie finished in a share of 14th after a closing 69.
Dyson, who birdied three of the last four holes in a flawless final round of 66, won the Asian Tour Order of Merit in 2000 but it took until the Indonesia Open in Jakarta in March for him to win on the European Tour.
"I've dedicated myself a lot better this year," he admitted. "I've been working out in the gym and also working a lot with (psychologist) Jamil Qureshi.
"I used to get annoyed a lot and it would cost me shots but now you almost wouldn't know if I'd made bogey or missed a short birdie putt.
"I am a different player and a different person compared to last year and it has has just been down to hard work and constant nagging from my coach and parents.
"It feels fantastic. To win once is a great achievement, to do it again in the same year - it just keeps getting better and better."
Dyson has also recorded six other top-10 finishes in 2006 and moves from 24th to 14th on the Order of Merit. He will also climb well inside the world's top 100 after starting the week at 110th.
He started the day three behind McGrane and still trailed Green despite a front nine of 34 with birdies at the seventh and ninth.
Five consecutive pars seemed to have ended his chances but the former Walker Cup star then birdied the 15th, 16th and 17th to catch Green on 14 under.
Green only made the cut right on the mark of one over par and, at that stage, was eight shots off the lead.
But the left-hander played the last 36 holes in 15 under par, carding a course-record 62 on Saturday and closing with a 65 yesterday which contained eight birdies and two bogeys.
The 35-year-old from Melbourne's sole Tour victory remains the Dubai Desert Classic in 1997 - when he pulled off a shock play-off win over Ian Woosnam and Greg Norman - and he has now finished second five times since.
"If you had said to me at the start of the week this is where I was going to finish, coming from the cut line to a play-off, I'd have been pretty happy with it because I haven't been playing that great and my putting has been pretty ordinary," Green said.
"But the weekend was very encouraging. My 62 will be something to remember as well - that's my new number on my race car (Green owns a V8 touring car).
"I've given it as good an effort over the weekend as I could have and I am pretty happy with that. I definitely know that I am playing good enough to win another golf tournament soon."
The best of the three Midlanders to play the whole tournament was Tom Whitehouse. The Birmingham man had lifted himself up the lead-erboard with Saturday's round of 65 and a 70 yesterday left him on six-under par and 90th in the European Tour rankings. The top 115 players keep their playing privileges at the end of the season.
Hereford's David Park finished one-over after weekend rounds of 71 and 72, but Robert Rock's early optimism completely fell away.
Having carded a 66 on Thursday, then slid to a 76 on Friday, the Staffordshire professional could do no better than 73 and 74 over the weekend, to finish five-over par.
Players and caddies wore black ribbons as a mark of respect following the death of Darren Clarke's wife, Heather and McGrane admitted: "It was tough out there.
"Everyone knew it was a matter of time but the two of us were out there with a chance to win the golf tournament and we get news like that."
