Isner used his big serve to upset world No.1 Rafael Nadal in the inaugural Laver Cup in Prague, reaffirming his reputation as a dangerous opponent. Returning for Team World in 2018, the 33-year-old American is in career-best form. He set a career-high ranking of No.8 in July, following a run to his first Grand Slam semifinal at Wimbledon.
The son of a builder and real estate agent, Isner started playing tennis when he was nine. A talented basketballer too, he opted to focus on tennis when he was 16 and played college tennis for the University of Georgia before turning pro. He and his wife Madison, who he married in December 2017, are expecting their first child in September. His hobbies include playing poker, golf, basketball and fishing.
Isner has finished ranked inside the world’s top 20 for the past eight consecutive seasons. Earlier this season he became the fourth player to hit more than 10,000 aces and won his first Masters 1000 title in Miami. He has featured in the two longest matches in history, with his recent Wimbledon semifinal against Team World teammate Kevin Anderson taking almost seven hours to complete.
