Langer finished with a 20-under-par aggregate of 264 to achieve his 37th European Tour win, climbing from fifth to fourth in the Ryder Cup points table.
His eight-under-par round yesterday consisted of eight birdies and 10 pars and he also shot 64 on Saturday with seven birdies and 11 pars - 15 under for the last two days with not a bogey in sight.
Almost as delighted as Langer was the Spaniard Ignacio Garrido, who had led overnight on 16 under par. Garrido could only manage a level par 71 yesterday to share second place with Sweden's Niclas Fasth, but by winning pounds 69,475 he clinched a Ryder Cup place at Valderrama next month.
It means that he and his father Antonio, who played in the 1979 Ryder Cup match at Greenbrier, West Virginia, will become the first father and son combination from the Continent to play in this famous competition.
Only Percy and Peter Alliss, who each played in the Ryder Cup when it consisted only of British and Irish players, have previously achieved this feat.
The US Open champion Ernie Els moved a step closer to his third victory of the year when firing an even-par 72 for a three-stroke lead after three rounds at the USPGA Buick Open in Michigan. The South African, who won the week after his US Open title as well, stood at 13-under-par on 203 in the pounds 1m event.Reuse content
