(CNN) -- England's John Parry claimed his maiden European Tour victory by winning the Vivendi Cup as Padraig Harrington tuned up for the Ryder Cup with a blistering final round 64 in Paris.
Parry, a former Walker Cup teammate of another Ryder Cup star Rory McIlroy, showed his pedigree in the paid ranks with a closing round 70 for a 17-under total of 271.
It gave him a two-shot winning margin over Swede Johan Edfors, who set the pace on the first day at Golf de Joyenval with a superb 61, but could not force home his early advantage.
Parry, who held the halfway lead at the Austrian Open before fading, avoided a similar slip up, but was briefly caught by another Swede Jarmo Sandelin.
But a run of three birdies saw him two ahead at the turn and he stayed clear in a tight finish.
"I felt nervous and just tried to control my emotions. I felt I was playing well, though, and my concentration was good," he told the European Tour official website.
Earlier, Harrington, who was picked by Ryder Cup captain Colin Montgomerie ahead of Paul Casey and Justin Rose, returned to his best form with an eight-under finish to claim joint eighth, having struggled to make the cut.
"I'm obviously happy," said the Dubliner.
"The week before a big event is all about seeing where your game is at and what needs working on.
"I am excited to get there and ready to go."
Former Ryder Cup star Sandelin finished joint third on 14-under with Danes Soren Kjeldsen and Mark Haastrup, France's Francois Delamontagne and Dutchman Robert-Jan Derksen.
