John Isner is known as a big Roger Federer's fan. The American player never hided his admiration for the Swiss, considered as the Greatest Player of All Time (GOAT) by many of his colleagues, including Isner. On Twitter, after winning his first Masters 1000 title ever, Isner, who defeated Alexander Zverev in the final, wrote: 'So this is what @rogerfederer feels like every other week.
@miamiopen . Happy Easter!!!' The 32-year-old beat Federer twice out of seven matches played. He prevailed at the 2015 Paris Masters on indoor hard in the third set tie-break, and in the 2012 Davis Cup between Switzerland and United States on clay in four sets.
