Muguruza splits from coach Martinez amid winless 2023

Martinez began working with her fellow Spaniard in 2019, although she was also with her when she won the Wimbledon crown in 2017 when Muguruza's coach Sam Sumyk was absent.

"Garbine and I have mutually agreed to end our employment relationship," Martinez, who also won Wimbledon during her illustrious playing career, confirmed via Twitter on Wednesday.

"They have been fantastic years, full of great emotions and wonderful experiences, both on and off the court. It has been a pleasure to work with you, Garbine. I wish you the best."

Muguruza was ranked No.1 in 2017 and as high as third at the end of 2021, but is now outside the top 100 after failing to win a match this year.
