The U.S. Tennis Association has appointed Craig Tiley as chief executive on a long-term contract, transitioning him from his role as Tennis Australia chief executive and Open tournament director.

Tiley brings global credibility, a history of innovative, player-first initiatives, and a track record of attendance and revenue growth from Tennis Australia under his leadership.

He has been a pivotal figure since becoming Australian Open director in 2006 and then Tennis Australia CEO in 2013, with participation and interest in tennis rising during his tenure.

Reactions to the five-set proposal are mixed among players: some express concerns about physical demands and injuries, while others see potential feasibility with conditions and discussions on whether to implement in early rounds or later rounds.

Tiley acknowledged mixed community reaction to Tennis Australia’s development efforts and emphasized the importance of consistent player development pathways amid cycles in national performance.

Earlier in 2026, he proposed extending certain women’s matches to best-of-five sets at the Australian Open, sparking debate on feasibility, player welfare, and audience appeal.

The broader context includes discussion about five-set matches for women at the Australian Open potentially starting in 2027 as part of the tournament’s evolution.

Board Chair Brian Vahaly underscored the need for a leader who can accelerate participation growth and leverage the U.S. Open as a platform for inspiration and expansion.

USTA is undergoing major modernization, including an $800 million renovation of Arthur Ashe Stadium, plus plans for a new player performance center and redesigned seating to support higher attendance and new ticketing tiers.

Tiley cited family reasons and the appeal of a fresh challenge in a larger market, noting his move brings him closer to relatives in the Chicago area.

Analysts note potential strategic ambiguities, such as whether Tiley’s authority will be greater in Melbourne than at the USTA, and how his leadership style will translate to the American federation.

Tiley’s appointment occurs amid the so-called Grand Slam arms race, with organizers pushing ongoing innovation, scheduling changes, and increased global profile to boost engagement and revenue.
