Justin Rose birdied the last at the Turkish Airlines Open to make it back-to-back wins and move to within touching distance of Tommy Fleetwood at the top of the Race to Dubai Rankings presented by Rolex.
The Rolex Series events have brought high drama to the European Tour all season and it was no different at Regnum Carya Golf & Spa Resort as Rose and playing partner Nicolas Colsaerts were tied at 17 under stood on the 18th tee.
Both men put their approaches to eight feet but it was Rose who held his nerve to make a birdie, sign for a 65 and claim a tenth European Tour title to heap the pressure on fellow Englishman Fleetwood heading into the final two events of the season.
The Olympic champion leapfrogged Sergio Garcia into second in the Rankings and the gap is now just 134,839 points at the top as Rose aims to be Europe's Number One for the second time after winning the Order of Merit in 2007.
South African Dylan Frittelli finished alongside Belgium's Colsaerts at 17 under after a 64, a shot clear of three-time Major Championship winner Padraig Harrington and two ahead of defending champion Thorbjørn Olesen.
As well as that victory at the Olympic Men's Golf Competition - which was not a European Tour win - Rose now has a Rolex Series victory to add to the 2013 US Open and two World Golf Championships, the latest of which came at last week's WGC-HSBC Champions.
The win also makes Rose just the third player to follow up a World Golf Championships win with another victory the following week after Tiger Woods and Rory McIlroy.
Rose holed a 15-footer for birdie on the second but three-putted from the fringe on the next before taking advantage of the par five seventh and hitting a sublime approach to tap-in range on the ninth.
That put him in a four-way tie for the lead at the turn alongside Frittelli, Harrington and Kiradech Aphibarnrat.

Frittelli had made five birdies in a row from the fourth which incredibly included chip-ins on the fifth, sixth and eighth, while Harrington made a birdie-bogey start then chipped in on the sixth and hit a smart approach into the ninth.
Colsaerts also started birdie-bogey then holed a monster putt on the fourth before holing a ten-footer on the 11th to briefly make it a five-way tie at the top.
The par fives were proving key and Frittelli birdied the 12th before Rose got back alongside by doing the same and both men then made the most of the 15th along with Colsaerts.
Harrington made one of the par saves of the season on the tenth after putting his tee-shot in the trees and second in the water before holing from 60 yards. He went bogey-birdie over the next two holes but when he put his second into the 15th to 12 feet for an eagle, he was in a share of the lead.
A brilliant shot from a fairway bunker from Colsaerts set up a birdie on the 16th and a four-way tie but Rose followed him in from eight feet to take the lead on his own.
Colsaerts made it three in a row on the 17th thanks to an approach to seven feet and he and Rose headed to the 18th tee neck-and-neck where, ahead on the green, Frittelli holed a 12-footer to bring a fist-pumping celebration and help set up the late drama.
Dane Olesen produced a late surge with three birdies from the 15th in his 66 to finish a shot ahead of Thai Aphibarnrat who closed with a 71 and England's Eddie Pepperell who signed for a 67.
Ireland's Shane Lowry, American Julian Suri and Paraguayan Fabrizio Zanotti were then at 13 under.
