John Isner to retire after 16-year career

American tennis player John Isner announced on Thursday that he will retire after the US Open, the final Grand Slam tournament of the season.

Isner, 38, posted a message on social media in which he thanked his coaches, family, and fans for "an incredible journey."

The 6-foot-10 American made his professional debut in 2007. He won 16 ATP titles throughout his career, most of them in the United States.

Isner is known for winning the longest tennis match in history. In 2010, at Wimbledon, he defeated France's Nicolas Mahut, 6-4, 3-6, 6-7, 7-6, 70-68. The match lasted 11 hours and 5 minutes, spanning three days.

Isner also holds the all-time record for aces served in professional tennis, with 14,411.

Isner's best Grand Slam performance was reaching the semifinals at Wimbledon in 2018. He reached a career-high ranking of No. 8 in the world that July.
