Fresh off his victory at Wimbledon, the No. 1 player in the world returns to Toronto, where he won the 2012 tournament. With defending champion Rafael Nadal out because of a wrist injury, Djokovic is the favourite to win the Rogers Cup this time around.
Federer hasn't won this event since 2006, but his run to the Wimbledon final showed he's still got something left in the tank at the age of 33. He lost the Wimbledon final in five memorable sets to Djokovic. How the Swiss star fares on hard courts in Toronto could shed some light on his hopes at the U.S. Open.
Canada's favourite son has made significant strides in his game this year, culminating with a trip to the semi-finals at Wimbledon. Raonic, who grew up in Thornhill, Ont., said he was "still pretty angry" about losing in those semi-finals but has faced some of the best this year in getting beaten by Federer, Djokovic and Nadal.
Murray, who won this tournament in 2009 and 2010, doesn't have a title in 2014 after winning Wimbledon as a home-country hero last year. Being back on hard courts could be just the ticket for the 27-year-old.
Ranked 183rd in the world at the start of the year, the 19-year-old Australian is all the way up to 69th. Kyrgios lost to Raonic in the quarter-finals at Wimbledon, and this will be a test to see if he has the game to win on hard courts.
