Miami: Roger Federer survived a brave challenge from American qualifier Frances Tiafoe before emerging with a 7-6 (7/2) 6-3 victory as he got his Miami Open title bid under way on Saturday.
Tiafoe, ranked 101st in the world, struggled against Federer’s serve but was strong on his own and forced a first set tiebreak in which the Swiss came out on top.
The 19-year-old son of immigrants from Sierra Leone then broke Federer’s serve in the first game of the second set only for the 18-time Grand Slam winner to break back twice and run out a comfortable winner in the end.
Federer was full of praise for his opponent and said he would have gained valuable experience from the contest.
“I hope he’s going to learn a lot from a match like this just because playing on a centre court with a lot of people, under pressure, saving break points, making break points, playing breakers. That’s what it’s about, and it should feed a player like him with a lot of energy moving forward,” he said.
Federer is in fine form having clinched the Australian Open and Indian Wells so far this year and extended his record to 14-1.
The 35-year-old is looking for his third Miami title following wins in 2005 and 2006.
Federer should have met Del Potro in Miami last year but the Swiss had to pull out with an illness and he says he is looking forward to renewing his rivalry with the South American
“We’ve had some epic matches against each other: Semis at the French, Olympic semis, finals at the US Open. You name it, we’ve had some really good ones,” he said.
Reigning US Open champion Stan Wawrinka got off to a solid start, beating Argentina’s Horacio Zeballos 6-3, 6-4 at Crandon Park on Saturday.
In the absence of Andy Murray and Novak Djokovic, the top two ranked players in the world, Wawrinka is the No. 1 seed and is fired up after reaching the final at Indian Wells last week, where he was beaten by Federer.
“I’m playing better tennis. I feel that I’m playing good here. I took the confidence from Indian Wells. So let’s see... When I’m playing well, when I am confident with my game, I know I can beat anybody,” said Wawrinka, who turns 32 on Tuesday.
“It has been quite tough conditions these last few days here. Raining, really windy today. It’s really windy on the court, so it’s never easy.
“I’m happy the way I was moving, the way I was playing, and my attitude in general was really positive,” added Wawrinka, who next faces Tunisia’s Malek Jaziri, a 6-3, 4-6, 6-3 winner over Spain’s Feliciano Lopez.
Wawrinka will face either Malek Jaziri next after the Tunisian beat Feliciano Lopez 6-3, 4-6, 6-3.
Australia’s Nick Kyrgios also progressed on Saturday enjoying a 6-4, 6-3 win over Bosnian Damir Dzumhur.
Fifth-seed Agnieszka Radwanska had her bid to repeat her 2012 success at Miami ended by Croatian veteran Mirjana Lucic-Baroni at Crandon Park on Saturday.
But second-seed Karolina Pliskova fought past Yulia Putintseva of Kazakhstan 7-5, 6-3 to move into the last 16 and Slovak Dominika Cibulkova also progressed with a comfortable two sets win over Belgium’s Kirsten Flipkens.
Lucic-Baroni is enjoying an unexpected upturn in her fortunes at the age of 35 and in January reached the semi-final of the Australian Open — 18 years after her previous appearance in the last four of a slam, in 1999 at Wimbledon.
The Croat was a teenage prodigy who appeared to have disappeared from the top tier of the sport but has fought her way back impressively in recent years and is now ranked 29th in the world.
The 6-0 6-3 scoreline emphasised her dominance over her Polish opponent on Saturday, as Radwanska acknowledged.
