KEY BISCAYNE, Fla. (AP) Now things will get a little more challenging for Frances Tiafoe at the Miami Open.
Tiafoe, a 19-year-old from Maryland, set up a second-round meeting against 18-time Grand Slam champion Roger Federer at the hard-court tournament by beating Konstantin Kravchuk 7-5, 5-7, 6-1 on Thursday.
Tiafoe hit 12 aces and accumulated 14 break points, converting five, on the 32-year-old Kravchuk's serve. This was Tiafoe's third career match victory at a Grand Slam or Masters event. Kravchuk, meanwhile, dropped to 0-7 overall this season.
