Samantha Stosur has split with her long-time coach David Taylor, the former US Open champion announced on Saturday.

Stosur said Fed Cup captain Alicia Molik would fill Taylor’s shoes in an interim role at the US Open starting on August 25, before the 29-year-old considered her long term options.

“After six years working together my coach David Taylor and I have decided to part ways,” Stosur said in a statement on the Tennis Australia website.

“We’ve had a tremendous working relationship and I owe so much of my success to Dave’s hard work and enduring support.

“Dave and I started working together during my comeback from Lyme disease, one of the most challenging times of my life.

“His dedication during the many highs and lows of my career has been unwavering both on and off the court.

“I wish Dave all the very best for the future.

“During the US Open I’ll be working with the Tennis Australia team, including Fed Cup captain Alicia Molik, and I’ll start thinking about longer term options after New York.”

Taylor was by Stosur’s side when she beat Serena Williams in the final of the 2011 US Open.

He also played a hand in Molik’s rise to the top 10.

Stosur had found some impressive form ahead of her return to Flushing Meadows, winning nine of 10 matches before falling to world No.25 Simona Halep in the third round of the Cincinnati Masters on Friday.
