It determined the USTA was 75 per cent to blame and Bouchard 25 per cent to blame.
Bouchard had sued the USTA for unspecified damages and testified its negligence led to her "serious head injury".
The US Tennis Association was found "mostly liable" by a NY jury on Friday for Canadian tennis star Eugenie Bouchard's locker room fall at the 2015 US Open, US media reported.
"Genie was vindicated yesterday with the verdict and now can put the case behind her".
It was confirmed that the USTA was found mostly liable for the slip, a jury ruling in the former world number five's favour, and would have to pay 75 per cent of the damages owed to Bouchard. They emerged with the deal but declined to disclose the terms. Minutes later, she fell on the tile floor of a physiotherapy room inside the locker room.
The 23-year-old had sustained a head injury which resulted in her withdrawal from the US Open doubles and mixed doubles events.
"I was laying there shocked, staring at the ceiling", she said.
Lawyers for the USTA countered that Bouchard should have known not to enter the area without being accompanied by a trainer or other tournament personnel and that the cleaning crew believed all the players had left for the night.
Bouchard, once ranked No. 5 in the world, slid steadily in the standings post-fall; she now is ranked 116th. After being ranked as high as No. 5 in the world and reaching the 2014 Wimbledon final, Bouchard is now the world's 116th-ranked player.
"Everyone who sponsored her before the U.S. Open continues to", he said, adding she remained "very marketable" because of a large following on social media.
