Roger Federer sauntered into the second round of the U.S. Open on Tuesday with a straight-sets triumph over Leonardo Mayer.
Top-ranked Novak Djokovic had dropped just three games in winning his opening match 24 hours earlier and Federer was similarly comfortable as he made light work of the world's 34th-ranked player.

Federer, a five-time winner at Flushing Meadows, eased through in 1 hour, 17 minutes, triumphing 6-1, 6-2, 6-2 to set up a meeting with Marcos Baghdatis or Steve Darcis.
Given his position as one of the highest-ranked non-seeds at Flushing Meadows, Mayer could have been expected to provide a stiff test to the veteran Swiss master.
But Federer was in control from the start, breaking at the first opportunity and swiftly moving into a 4-0 lead courtesy of a running forehand pass down the line as his opponent struggled badly.
Mayer earned a break point in game five, only for the second seed to respond with successive aces on his way to a hold.
The first set was duly secured in 22 minutes with a love service game and Federer was similarly dominant in the second, giving up just four points on serve and breaking Mayer again at 2-2 and 4-2.
When Mayer dropped serve again early in set three, it was clear there was no way back for the Argentinian.
Yet another break put Federer 4-1 ahead and the match was soon brought to a swift end.
