Roger Federer has withdrawn from next month’s Rogers Cup in Toronto as he continues to pick and choose events to prolong his career.
World number 2 Federer has played seven singles events so far this year as he looks to stay fresh for is favoured events.
The Swiss maestro, 36, became a 20-time Grand Slam at the Australian Open in January and also won titles in Rotterdam and Stuttgart.
But he lost in the finals at Indian Wells and Halle and was beaten in a dramatic Wimbledon quarter-final by finalist Kevin Anderson of South Africa.
“Unfortunately with scheduling being the key to my longevity moving forward, I have regrettably decided to withdraw from Toronto,” Federer said.
Nine of the top 10 ranked players in the world, including Rafael Nadal and Wimbledon champion Novak Djokovic, will play at the ATP World Tour Masters 1000 event, starting on 4 August.
Federer was beaten in the final of last year’s tournament in Montreal by German youngster Alexander Zverev.
