Samantha Stosur admits splitting with her long-time coach nine days out from the US Open wasn't flash timing.
Stosur will enter the final grand slam of the year starting on Monday without David Taylor for the first time in almost six years.
Australia's big title hope beat every single player currently ranked in the top 10 during that partnership, including all-conquering world No.1 Serena Williams in the 2011 final in New York.
But the 29-year-old's preparations this year took a surprise twist when Stosur announced she had parted ways with Taylor less than a fortnight after downing world No.2 Victoria Azarenka for the first time in nine meetings in the final of the Southern California Open.
The breakthrough victory over the two-time Australian Open champion ended a two-year title drought for Stosur.
''Dave and I, we had been together for a long time. It was almost six years,'' Stosur said.
''We had some great moments in that period of time. [But] as these little periods have gone on, I think we both were kind of feeling that we'd almost come to the end.''
Stosur hasn't spoken to Taylor since their abrupt split, which came after her third-round loss to Romanian Simona Halep at the Cincinnati Masters. ''But I'm sure in time I'd love to still be in contact with him,'' she said.
Fed Cup captain Alicia Molik will assist Stosur during the US Open.
