Padraig Harrington showed signs of getting his game in shape before next week's Ryder Cup with a third round of 69 in Paris on Saturday.
Harrington only made the cut at the Vivendi Cup right on the mark of two under par courtesy of three birdies in his last six holes.
But the Dubliner recovered from a shaky start on Saturday to card a total of eight birdies on the Marly course.
Harrington dropped a shot at the first and birdied the third, but then ran up a double bogey on the fourth and bogeyed the fifth to no doubt leave European Ryder Cup captain Colin Montgomerie a worried man.
However, the 39-year-old - one of Montgomerie's three wild cards for Celtic Manor - rediscovered his composure to par the sixth and then birdie four of the next five holes.
Further birdies followed at the 13th and 16th and, after a bogey on the 17th, Harrington finished in style with a birdie at the last.
At five under par, the triple major winner is 10 shots adrift of leader John Parry.
