(corrects third-set score to 7-5 in first para)
PARIS May 31 (Reuters) - Roger Federer's French Open campaign gained momentum as the Swiss second seed eased past France's Julien Benneteau 6-3 6-4 7-5 to reach the fourth round in awe-inspiring fashion on Friday.
There was the usual array of running aerial forehands, gravity-defying drop shots and whipped backhands as the former world number one booked a meeting with American Sam Querrey, the 18th seed, or French 15th seed Gilles Simon.
Benneteau, the 30th seed, broke in the first game to open a 2-0 lead but 17-times grand slam champion Federer kept his cool and turned the situation around in no time.
Benneteau, who has been struggling with a groin problem, bowed out on the first match point when he could not retrieve yet another Federer forehand after 91 minutes.
