Rogers Cup Standout: Milos Raonic

Age: 26

Rank: No. 10

Career Best Rogers Cup Performance: 2013 finalist

2017 High: A year after making the Wimbledon final with a stunning victory over Roger Federer, Milos Raonic was on the opposite trajectory entering the grounds of the All England Club this time around. But down two sets to one in the fourth round, the 26-year-old dug deep against rising phenom Alexander Zverev, finding a way to squeak out a tight fourth set before cruising in the fifth to earn his place in another Grand Slam quarterfinal, where he lost to Federer.

2017 Low: After losing to Rafael Nadal in the Australian Open quarterfinals, Raonic struggled with hamstring problems, playing just five matches between when he left Melbourne and May, withdrawing from tournaments in Delray Beach and Miami in the final and third round, respectively.

Best Social Media Moment: John McEnroe isn’t necessarily the first person you’d think of if in need of a therapist. But during the French Open, the Canadian posted a picture of himself on a Eurosport set lying in bed with his former coach, McEnroe, just a few feet away in a sleeveless shirt apparently putting a smile on his old pupil’s face. That is Instagram gold.

Summer Outlook: There is no doubt that Raonic will be a threat in Montreal and Flushing Meadows if he stays healthy. The Canadian has one of the biggest serves in the game, which will enable him to hold against virtually anyone else in the field. When you think of the best returners in the world, you think of Novak Djokovic, who will miss the rest of the season, and Andy Murray, who has struggled for much of this season.

Raonic has already beaten Rafael Nadal once this year—could he spring another upset? Also, under the radar, Raonic began working with former top-ranked doubles player Mark Knowles in June. While Knowles is not as big of a name as McEnroe, Richard Krajicek or Carlos Moya, he has won Grand Slams and been around the game for years.
