London - 2013 Wimbledon finalist Sabine Lisicki has split with coach Martina Hingis on the eve of this year's tournament, the German player announced on her Facebook page.
Lisicki, who suffered from a wrist injury and had to quit a Roland Garros second-round match, made the announcement the weekend before the start at the All England Club.
The split was couched in terms of a "mutual agreement".
The player said that "different concepts" on her tennis also played a role in the parting. Even as the coaching relationship changed Lisicki hinted that she and the Swiss might still try it on in doubles again.
"I wish her the best of luck, and maybe we are playing doubles together here and there," said the WTA number 19, who lost the Wimbledon singles final a year ago to the now-retired Marion Bartoli.
Lisicki and her 33-year-old coach played four events together in 2014, winning the Miami title but not going past the second round in the other three. They last took to the court together in Rome in May.
Lisicki will continue to be guided by her father during Wimbledon after the split with Hingis.
It was the second short-term coaching job for Hingis, who spent several months in early 2013 with Russian Anastasia Pavlyuchenkova.
Hingis has a wild card into the Wimbledon doubles, teaming up with Russian Vera Zvonarewa.
