Novak Djokovic eased to victory on his return to action, as he defeated Florian Mayer - losing just three games at the ATP Rogers Cup.
The world No 1 and top seed, needed just 55 minutes to reach round three as he came through 6-2 6-1 in his first outing since his defeat in the Wimbledon final to Andy Murray.
The Serb claimed four breaks of serve before saving a 0-40 deficit in the final game as he stretched his winning run at the event to 11 matches.
His conqueror at SW19, Andy Murray, takes to court later today as he begins his campaign against Marcel Granollers after the Spaniard defeated Grigor Dimitrov in straight sets.
Elsewhere on Tuesday, there were some surprise defeats for the seeds with Nicolas Almagro and Gilles Simon exiting the tournament, while John Isner was toppled by wildcard Jaroslav Pospisil, losing two tie breaks after he had taken the opening set.
Pospisil's victory means he joins fellow Canadians Milos Raonic, Jesse Levine, Frank Dancevic and Filip Peliwo in the second round, a tournament record for the Toronto event.
