Let's make this birthday one to remember.

40 years old (Born on April 26, 1985)

Happy Birthday, John Isner! Wishing a grand celebration to the man whose matches sometimes need their own calendar. Your iconic Wimbledon marathon match is legendary—you're basically the reason they decided keeping track of tennis scores needed more numbers and daylight savings.

Congratulations on your remarkable achievements—including consistently dominating service games and setting ace records like it's just another Tuesday afternoon on court. Keep serving aces, chasing victories, and giving us thrills each season (we'll make sure the snack stand stays open). Here's hoping you enjoy your birthday with shorter rallies than usual and cake taller than you are!
