Michigan State's Harry Jadun steps down; Mike Flowers to lead men’s tennis

Only a few days after its Big Ten championship season ended in the NCAA Tournament, Michigan State’s men’s tennis program is making a leadership change.

Michigan State head coach Harry Jadun is stepping away from the coaching ranks after four seasons leading the Spartans’ men’s tennis program, according to an athletic department release Tuesday. His top assistant, Mike Flowers, will take over the program after spending four years as Jadun’s assistant.

The reigning Big Ten coach of the year, the 32-year-old Jadun is pursuing career opportunities outside of tennis and collegiate coaching. He had not responded as of publication when contacted by The Detroit News on Tuesday afternoon.

“I am deeply grateful to Michigan State University, the Athletic Department and the entire Spartan community for the privilege and the opportunity to serve as the head coach of Michigan State men’s tennis,” Jadun said in a statement released by Michigan State, also thanking his wife Rachel and son Rami in the statement. “This University and the Spartan Tennis program has given myself and my family so much since my time growing up in East Lansing. As an alum, student-athlete and coach, I have learned so many valuable lessons and developed relationships here at Michigan State that I will continue to cherish for the rest of my life. This was not an easy decision, as this program means the world to me, but I am so excited for the future of Spartan Tennis and proud of what we have built together.”

An East Lansing native, Jadun played for Michigan State from 2011 to 2015 and earned All-American honors in doubles while leading the Spartans to their first team NCAA Tournament berth in 2013. In 2017, he joined the staff of his eventual predecessor Gene Orlando as an assistant coach. In June 2022, Jadun took over MSU’s program as head coach.

Before he was hired at MSU, he spent a month at Illinois as an assistant coach in May 2022.

“We appreciate and celebrate the leadership Harry Jadun has provided our tennis program, including the last four years as head coach,” Michigan State athletic director J Batt said. “His journey began as an All-American student-athlete for the Spartans, continued as an assistant coach and culminated by directing a historic season for the tennis program. While he's made the decision to step away from collegiate coaching to pursue a new career path and focus on his family, he's clearly a Spartan for Life. We respect his decision and wish him well in his new journey.”

Jadun coached Michigan State to a 70-40 record in four seasons, including a school record 23-7 campaign in 2023-24 and a 19-9 record in 2025-26, 12-1 in Big Ten play to win Michigan State’s first Big Ten championship since 1967, the only two in program history. Michigan State also won the 2026 Big Ten Tournament, but lost in the second round of the NCAA Tournament to South Carolina on Saturday, its third straight second-round exit.
