Introduction

John Robert Isner (born April 26, 1985) is an American former professional tennis player whose career was defined by power serving, endurance in long matches, and a late-blooming path through college to the global stage. At 6 ft 10 in (2.08 m) and with one of the most lethal serves in the history of the game, he became one of the most recognizable figures in modern men’s tennis.

Early Life and Background

Isner was born on April 26, 1985 in Greensboro, North Carolina, U.S.

He didn’t start playing tennis intensely until around age 9 or 10, having a more gradual introduction to the sport.

For college, he committed to the University of Georgia, where he had a standout collegiate career.

His time in college delayed his turning-professional, relative to many tennis players, but also allowed him physical and mental maturity before entering the pro circuit.
