THE United States Tennis Association (USTA) has announced an $800 million (£598.9m) transformation of the US Open site, marking the largest infrastructure investment in its history.

The centrepiece of the project was a major renovation of Arthur Ashe Stadium alongside plans for a state-of-the-art player performance centre, to be named in honour of US tennis legend Billie Jean King.

The upgrades, due to be complete by 2027, are expected to take place in three stages to avoid interrupting the 2025-26 US Opens.
