Federer rolls into fourth round at Miami Open

KEY BISCAYNE, FLA. >> Roger Federer took a look around as he entered the stadium court at the Miami Open, already feeling the energy of the crowd. He gave them quite the show. Federer advanced to the fourth round at Key Biscayne on Monday, the No. 4 seed beating Juan Martin del Potro 6-3, 6-4 on Monday. Federer, who was facing the 29th-seeded del Potro for the first time since 2013, never lost serve and improved to 15-1 this year.

He broke del Potro twice, once in each set, and that was all he needed.

“I feel like I earned it more,” said Federer, the 2005 and 2006 champion on Key Biscayne. “I was more the aggressor. It was more my racket, and I like it that way.”

The first break put him up 5-3 in the first set, and Federer then fought off four break points in the ensuing game before closing out the set.

Another break for a 3-2 lead in the second set, not long after del Potro got his oft-problematic left wrist taped on a changeover, put Federer in full control.
