The most touching part of Alexander Zverev's 1st #USOpen victory speech
"I want to thank one more person who is never actually watching my matches but is the most important person in my tennis life and in my life in general. Because when your 4-year-old son gets diagnosed with diabetes and doctors in the office tell you that life and sports will be very, very limited for that child it takes a very, very strong mother to walk out of those offices and say, 'My son will be whatever he wants to be, if he wants to be a tennis player he will be a tennis player, if he wants to do something else he will do something else. But this illness will not define us.'"
