Maria Sharapova has sacked coach Jimmy Connors after losing her first match since hiring him in July.
BBC Sport are running with quotes from a Sharapova statement that confirmed the split just a week ahead of the start of the US Open.
"It's not the right fit for this time in my career," it read.
Sharapova crashed out of the Cincinnati Open to American Sloane Stephens in a performance that was littered with mistakes.
Connors was present to see the world number three make 62 unforced errors as she was defeated by the promising 20-year-old 2-6 7-6 6-3.
Rumours of the split emerged on social media sites soon after the defeat, despite Connors tweeting as if he was still in the job in the aftermath.
"Every good round starts with a bogey - not the start we wanted, so back to work tomorrow,” he said.
Despite the pair seeming an odd fit when it was announced they would be working together, to split after a single match could be seen as being rash on the part of Sharapova.
The 2012 French Open champion was returning from a week long injury layoff, so not being on her game could have been excused.
Sharapova will now have no coach when the US Open begins on August 26, which could further affect her ability to challenge Serena Williams and Victoria Azarenka for the title.
