David Horsey held his nerve to beat Ireland's Damien McGrane to claim the Russian Open in a play-off at the Tseleevo Golf and Polo club in Moscow.
England's Horsey had shared the overnight lead with Scot Peter Whiteford but they both endured a disastrous front nine and dropped off the top of the leaderboard with McGrane cutting through the pack with seven birdies.
But the Irishman bogeyed the 18th hole to give the chasing pack a chance of catching him on 13 under for the tournament.
Scott Jamieson was unable to do so as he finished one stroke behind McGrane but, thanks to a birdie and an eagle on the last four holes, Horsey was able to draw level with the clubhouse leader.
Horsey only needed one play-off hole to triumph as McGrane found a greenside bunker on the 18th and missed a 10 foot putt meaning Horsey was able to two putt his way to victory. The win represented Horsey's third European Tour win and his first for over three years.
After only managing a level par 72 during his final round, Horsey admitted that he thought he had blown his chance of victory. However, a brilliant chip in from off the green for an eagle on the par five 17th gave him the opportunity to take the tournament into a playoff.
Relief for Horsey
Asked how he felt after winning his first trophy since April 2011, he told Sky Sports: "Relieved is the word that sums it up.
"I had a bit of a mare on a couple of holes over the back nine and didn't really know where I was in the tournament until 17.
"I suddenly realised I was only three behind but needed to do something drastic quite quickly. I managed to chip in and, while I was trying to make birdie at the last, I didn't realise he'd dropped one.
"I got up and down to get in the play-off and I was fortunate to win that."
Horsey could now move into the top 120 in the world rankings from his current position of 198 as he continues his fine campaign which now stands at five top 10 finishes in 16 events.
England's Sam Hutsby had an impressive final round as he carded a four under par 68 to claim fourth ahead of Whiteford who will be disappointed with a three over par as he threw away his share of an overnight lead with four bogeys and a birdie.
Sweden's Krister Eriksson and Belgium's Thomas Pieters finished on nine under for the tournament and a tie for sixth place.
Italian Andrea Pavan couldn't replicate his third round of 64 and he had to settle with a level par 72 for his final round to take a share of eighth with Germany's Maximillian Kieffer.
