Federer took control of the match from the get-go and promptly proceeded to dismantle Del Potro's offensive. The Swiss maestro hit 12 aces and 35 winners, making 75 percent of his first serves and winning 83 percent of them.
In winning this match, Federer has avenged what he refers to as "one of the bigger losses in my career". Next up for Roger Federer is former top-10 player James Blake. The world No. 3 has an impressive 9-1 head to head record against the American.
In other news, Jo Wilfired Tsonga, the world No. 10, defeated Marin Cilic 6-3, 6-4, advancing to the second round and Ivan Dodig—Rafael Nadal's conqueror in Montreal last week—caused another upset by defeating Latvian Ernest Gulbis in straight sets 6-3, 7-6 (3).
Elsewhere, Kazakhstani Andrey Golubev recorded a confidence-boosting 3-6, 6-4, 6-1 win over No. 16 seed Stanislas Wawrinka of Switzerland. It was Golubev's first tour-level match win since March. He had lost 18 straight matches and dropped outside the Top 100 of the ATP World Rankings.
On the women's side, Serena Williams came through a testing match against Lucie Hradecka 6-3, 7-6 (5) to set up a mouth-watering second round encounter with Samantha Stosur whom she defeated in the WTA Toronto final last week. Maria Sharpova and Wimbledon ladies champion Petra Kvitova also won their respective matches.
