Eight of the final sixteen in Key Biscayne have been determined after Sunday’s exciting day of tennis.
No. 19 seed Hyeon Chung booked the first ticket to the fourth round with a dominating win over American Michael Mmoh 6-1, 6-1. He will take on Joao Sousa, who came back from a 1-6 first set loss to Jared Donaldson to take the match 6-3, 6-4.
Joining him not long after is 2014 US Open champion Marin Cilic, who fought off Vasek Pospisil 7-5, 7-6(4). The Croatian is the top remaining player in the draw after Roger Federer’s stunning upset the day before, and he will take on American John Isner. Isner sealed his first round of 16 appearance at Crandon Park since 2015 with a 6-4, 6-3 win over Russian Mikhail Youzhny.
Juan Martín del Potro, the 2009 US Open champion, outplayed Kei Nishikori for a 6-2, 6-2 win, a raucous crowd cheering on the Argentinian with chants of “Ole!” between games.
Del Potro now has a date scheduled with No. 22 seed Filip Krajinovic, who avenged his compatriot Novak Djokovic’s loss by defeating Benoit Paire – the man who knocked out Djokovic – 6-3, 6-3.
The biggest upset of the day was pulled by Frenchman Jeremy Chardy, who ended No. 3 seed Grigor Dimitrov’s title hopes in straight sets by a final score of 6-4, 6-4.
The night ended with a fierce battle between No. 13 seed Diego Schwartzman and No. 20 seed and 2016 Wimbledon finalist Milos Raonic, with Raonic coming out on top. The Canadian moves on to a matchup with Chardy in the fourth round.
