In his 50th Masters final, the Swiss fourth seed produced some typically sublime groundstrokes and wrapped up the match in an hour and three minutes.
Tsitsipas elaborated on Twitter in response to a question from a Twitter follower, saying that despite Federer being his "favourite" the 20 time Grand Slam champion, along with the likes of Rafa Nadal and Novak Djokovic, are protected by umpires.
Isner double faulted for the second time and when he hit hopelessly long once again, Federer had sealed the opening set without breaking sweat.
In a matchup of elite return against elite serve, Federer's return game gained him an advantage from the start.
Isner, ranked world No. 9 and whose only other ATP Masters 1000 victory was a year ago in Key Biscayne, entered Sunday holding serve 56 of 60 times (93 percent) during the tournament.
"It's a awful feeling, because you're on an island out there".
"It was just important to keep on doing what I was doing, and if he's hurt, well, then so be it, and bad luck for him", Federer said. With Juan Martin, I think he will find a way back which I'm confident he will."Roger Federer said".
Tebbutt: Night school for Denis
After just five games of the first set, Isner already had his work cut in trying to halt Federer's charge to the title, down two breaks with the Swiss on control.
One telling statistic makes that clear, the record for number of matches in ATP tourneys. So they should just, based on what happens, take those decisions and I really feel the umpires do that.
"Roger Federer is always going to be my favourite player no matter what". The Swiss star has made a giant leap since, first earning 600 points for his runner-up showing in the California desert and then adding 1,000 points on Sunday after lifting his 28th Masters 1000 title in Miami. He won the title in 2005, 2006 and 2017 before it moved from Key Biscayne to its new home this year in the Dolphins' complex.
The duo of Elise Mertens of Belgium and Aryna Sabalenka of Belarus won the women's doubles final over Australia's Samantha Stosur and China's Zhang Shuai, who were seeded sixth, 7-6 (5), 6-2 on stadium court later Sunday afternoon. They combined for six aces.
