Via Nike Tennis June 20 #ENDLESSTENNIS Open Challenge 9: Favorite Fan You didn't get where you are by yourself. Today's challenge is all about knowing that behind every great player is an even better team of supporters. Has your coach pushed you further than you thought you could go? Has your best friend or parent been to every match you've ever had? Whoever it may be, they've supported you through it all and shaped your game; it's time to give them some love.
