J.J. Wolf, 24, is surely part of the new generation of American tennis players who are expected to achieve significant results on the ATP Tour in the years to come.
Jeffrey John Wolf was born on December 21, 1998, in Indian Hill, Ohio, to Jeff and Brooke Wolf. His family has a sporting pedigree, so it was expected that he would be involved in sports.
His father, Jeff, played basketball at Rollins College and is a member of the school’s athletics hall of fame, and his mother, Brooke, was an All-MAC tennis player at Miami. He has a younger sister, Danielle, who also plays tennis.
His grandfather Charles played football at Notre Dame and later became a professional basketball coach. He coached two NBA teams, the Cincinnati Royals and the Detroit Pistons.
J.J. started playing tennis at a young age, was introduced to the sport, and was coached by his father, Jeff. He has been ranked in the top five of his recruiting class since he was 10 years old and has been ranked as high as 14 in the ITF world junior rankings.
After finishing Cincinnati Country Day School, he attended Ohio State College, where he played for the Buckeye tennis team and had a tremendous first season.
During his college years, he won many honors, such as Big Ten Freshman of the Year, Big Ten Player of the Year, First Team All-Big Ten, and All-American.
He began playing semi-pro tennis in 2016, and the next season, he won USA F34, Harlingen Open, an ITF Futures tournament. Three years later, in July 2019, he signed with Topnotch Management to play professionally.
Who Is Jeffrey John Wolf’s Coach?
Since attending college, J.J. has been coached by David Kass and Patrick Thompson.
David Kass
David Kass was born on 16th June 1970 in Bexley, a suburb of Columbus, Ohio.
He is a former tennis player who won junior titles at the Orange Bowl and Easter Bowl and, along with Jim Courier and Michael Chang, represented the USA at the 1986 World Youth Cup.
David played college tennis at the University of Michigan, where he was a three-time All-American and was the 1992 Big Ten Player of the Year. He didn’t have any success on the ATP Tour as a professional, reaching a career-high singles ranking of 288 in the World.
After retirement, he founded the Kass Tennis Academy, a high-performance training base for juniors and pros with on- and off-court programming oriented to maximize each player’s long-term potential.
“JJ is one of the best athletes in the world of junior tennis,” said Kass about his trainee at the beginning of their collaboration. “He has a huge forehand and a big first serve. His potential is unlimited, and he can be an All-American early in his career.
Patrick Thompson
Patrick Thompson is a tennis coach who works at the Kass Tennis Academy and, together with David, is responsible for Wolf’s development as a professional tennis player.
He travels with Wolf, accompanies him at the tournaments, and can be seen in his box with Kass.
Coached by Kass and Thompson, J.J. won his first Challenger at the Columbus Open at the beginning of the 2019 season. As soon as he turned pro, Wolf won his second tournament on the ATP Challenger Tour at the Champaign-Urbana Open.
In January 2020, he started the year by winning the Challenger in Nouméa, defeating Yuichi Sugita in the final.
Then, in March, he won the Columbus Open for the second year in a row, defeating Denis Istomin in the final. With these results, he made his top 150 debuts, reaching the World no.144 ranking.
During season 2020, he made his Grand Slam debut, playing at the US Open, where he reached the third round but was defeated by Danil Medvedev.
In 2021, Wolf underwent two hernia surgeries and could not compete for seven months.
He returned in style the following season, winning his first two Masters, one at Indian Wells and one at Miami. He also entered the top 100 in the World for the first time.
At the US Open, he repeated his best result at the Grand Slams, playing in the third round. By the end of the season, he played at the Firenze Open and reached the first ATP final of his career, which he lost in straight sets to Felix Auger-Aliassime.
Due to his good games throughout the year, he reached his career-high ranking of World No. 56.
Wolf had a great start to season 2023. On his Australia Open debut, he reached the fourth round of a Grand Slam for the first time in his career, but he lost to fellow American Ben Shelton in five sets.
