England's David Horsey recovered from a front-nine collapse to force a play-off against Damien McGrane before pushing on to victory at the Russian Open.
The 29-year-old from Alderley Edge shared the overnight lead with Peter Whiteford heading into the final round at the Tseleevo Golf and Polo Club in Moscow, but both men tumbled out of the top spots while McGrane was cutting through the pack with seven birdies.
The Irishman looked set to beat Scott Jamieson, who finished 12 under for the tournament, by two strokes, yet he bogeyed the 18th as Horsey found a birdie and an eagle in his last four holes.
Only one play-off hole was needed. McGrane found the greenside bunker on 18 before missing his putt from 10 feet, and Horsey duly wrapped up his third European Tour win by two-putting for the win.
Hampshire's Sam Hutsby finished particularly strongly in the Russian capital, the 25-year-old signing for a four-under 68 to take fourth place ahead of Whiteford, whose three-over final round saw him mix four bogeys with a birdie on 17.
Krister Eriksson of Sweden and Belgium's Thomas Pieters were tied for sixth place at nine under for the tournament while Italy's Andrea Pavan could not build on his Saturday score of 64, instead coming back to the clubhouse in 72 to take a share of eighth place with Maximilian Kieffer of Germany.
