Novak Djokovic cruised to a 6-3, 6-3 win over Brit Kyle Edmund Friday night in his Miami title defense. The Serb improved to 23-1 on the season as he bids for his sixth Miami title and third straight.
The big story of the day was the withdrawal of Roger Federer who was beset by a stomach virus. But his opponent, Juan Martin del Potro, couldn’t capitalize as the Argentine was stunned by countryman and lucky loser Horacio Zeballos 6-4, 6-4.
At one point during the match, del Potro had the trainer look at his left wrist.
“He played well,” said del Potro of his opponent. “He’s a lefty, he can play to my backhand easier than anyone else. He played very smart.
“I was suffering a little bit. It was worse than in my first match, but I hope it’s nothing dangerous. I will see what’s going on after today and see if I can practice tomorrow, if I can hit a few backhands. It’d be a surprise for me to win a match at this moment because I’m not 100% yet. But I’m here playing tennis. That’s good for me.”
Former finalist David Ferrer survived a couple of set points in the first to deny 18-year-old future star Taylor Fritz 7-6(6), 6-1.
Another 18-year-old also went down as the struggling Steve Johnson Knocked out Alex Zverev in two breakers.
Marin Cilic and Gilles Simon advanced to a third round meeting. Richard Gasquet, Dominic Thiem and Tomas Berdych who earned a walkover also reached the third round.
On tap Saturday are debuts from former champion Andy Murray along with Rafael Nadal, John Isner, Kei Nishikori and Stan Wawrinka.
