British number one Emma Raducanu has announced her split from coach Torben Beltz after only five months.
The US Open champion joined forces with Beltz in November following her Grand Slam victory, with Andrew Richardson parting company with Raducanu last year.
However, Raducanu has struggled to hit the same heights since the US Open, and the 19-year-old believes that now is the time to explore a "new training model".
"I want to thank Torben for his coaching, professionalism and dedication over the last half a year. He has a huge heart and I have enjoyed our strong chemistry during the time together," BBC Sport quotes Raducanu as saying.
"I feel the best direction for my development is to transition to a new training model with the LTA supporting in the interim."
Raducanu won back-to-back matches for the first time in 2022 at the Stuttgart Open but was knocked out in the quarter-finals by world number one Iga Swiatek, and she enters as the ninth seed for the upcoming Madrid Open.
