Jeffrey John “J.J” Wolf was born on December 21, 1998, in Cincinnati, Ohio, United States, to Jeff and Brooke Wolf. His mother, father, and sister all played tennis, and his mother and sister did so at university. Wolf started playing tennis through mixed doubles on family vacations.
Like his mother and sister, Wolf played college tennis at the Ohio State University. He was named the 2017 Big Ten Freshman of the Year and First-Team All Big Ten. On April 23, 2019, Wolf became the No. 1 ranked college player in the United States.
The American began to regularly play on the ATP Challenger Tour in 2019 after the end of his college career. He defeated Mikael Torpegaard to claim his first title in Colombus before claiming a second in November 2019 against Sebastian Korda in Champaign.
Three more triumphs on the Challenger circuit followed in the next two years. These were in Noumea, Las Vegas, and Colombus once again. He defeated Yuichi Sugita, Denis Istomin, and Stefan Kozlov in those finals.
Wolf did not play much outside the Challenger Tour until the second half of 2022. However, he did have a run to the third round of the 2020 US Open as a wild card. The American defeated Guido Pella and Roberto Carballes Baena before exiting to Daniil Medvedev.
He repeated that achievement at Flushing Meadows in 2022. He claimed an excellent triumph against the 16th seed Roberto Bautista Agut in the opening round. Wolf then beat Alejandro Tabilo in four sets, coming from a set down to achieve this. Nick Kyrgios ended his tournament in straight sets.
Wolf reached his first ATP Tour final in October 2022 at the Firenze Open. He overcame Francesco Mastrelli, Maxime Cressy, Alexander Bublik, and Mikael Ymer to set up a final against Felix Auger-Aliassime. Unfortunately for Wolf, the Canadian was too good, and he fell to a 4-6, 4-6 defeat.
He built on that momentum by starting 2023 with a run to the fourth round of the Australian Open. Wolf triumphed against Jordan Thompson, Diego Schwartzman, and Michael Mmoh in Melbourne. He lost an epic fourth-round battle to Ben Shelton 7-6, 2-6, 7-6, 6-7, 2-6.
Wolf also had some solid runs at the ATP Masters 1000 events in 2023. He made the third round of the Italian Open before doing even better at the Shanghai Masters, reaching the fourth round.
