The lawyer for the former Wimbledon finalist Eugenie Bouchard says he will be pressing for millions of dollars in damages, after Bouchard won her long-awaited court case against the United States Tennis Association.

In a decision reached late on Thursday night, UK time, a jury in Brooklyn found that the USTA should bear 75 per cent of responsibility for a fall at Arthur Ashe Stadium three years ago, which left Bouchard with concussion.

The accident happened when Bouchard - who is 23 - returned to the players’ area after a late-night match and slipped on a cleaning substance that had been left out on the floor of the physiotherapy room. There were no other people present at the time.

Physiotherapist Kristy Stahr, who was the only witness called by the USTA, told the court: “We just assumed that she [Bouchard] had left.”

The USTA’s lawyer also admitted that staff are not supposed to start cleaning the floor until the last player has gone home for the night.
