MIAMI GARDENS, Fla. — No matter how smooth and imperious Roger Federer looked in the Miami Open final, whipping winners seemingly on demand and breaking big John Isner’s serve on four occasions, Federer knows all too well how fragile this all is as the shadows lengthen.
There can be no doubt that Federer is back near top gear at 37. He is moving like a man 10 years younger and has a sparkling 18-2 record this season. After his 6-1, 6-4 victory on Sunday, he is the first man or woman to win more than one singles title in 2019.
