Playing career

John Isner was born in Greensboro, North Carolina, in 1985. At 208 cm he built his game on one of the biggest serves the sport has seen. He played four years at the University of Georgia before turning professional in 2007, and that summer reached the Washington final as a late wildcard.

He won 16 ATP singles titles, including the Miami Masters in 2018, and reached No. 8 in July 2018 after his Wimbledon semi-final. He served 14,470 aces in tour-level matches by ATP count, the record; he passed Ivo Karlović's 13,728 at Wimbledon in 2022. He also won eight doubles titles. He retired after the 2023 US Open, where he lost his last singles match to Michael Mmoh in a fifth-set tiebreak.

Ending the Casino Curse

He took a late wildcard into Newport, missing his brother's wedding to play, and became the first top seed to win the event since it began in 1976, ending what was known as the Casino Curse. "It was perfect serving conditions for me, this court, this tournament," he said.
