New York (Reuters): After two marathons, Roger Federer had the after-burners on, sprinting past Spaniard Feliciano Lopez 6-3 6-3 7-5 and into the fourth round of the US Open on Saturday.

Chasing a sixth US Open title, Federer needed just one hour and 46 minutes under a closed roof at Arthur Ashe Stadium to put away the 31st seed Lopez, leaving plenty in the tank after being forced to go the distance in his opening two matches.

It has been a far different start to the US Open than Wimbledon where an economical Federer stormed to his 19th grand slam title without dropping a set.

In his opening two matches at Flushing Meadows, a misfiring Federer had been forced to five sets, first by American young gun Frances Tiafoe then Russian veteran Mikhail Youzhny.

After being broken eight times and committing a whopping 124 unforced errors in those first two contests, a focused Federer tightened up his game against Lopez, operating with his hallmark efficiency.
