Sabine Lisicki announced on her Facebook page this weekend that she’ll no longer be working with Martina Hingis, though she did leave the door open for future collaboration on the doubles court.

“Martina and I have parted ways on a mutual agreement,” Lisicki wrote. “After winning the doubles title in Miami she found the desire to play doubles again. I wish her much luck and maybe we play a few doubles here and there!”

The split was confirmed by Lisicki’s agent via email. Lisicki will continue working with her father, Dr. Richard Lisicki, as her coach.

Lisicki, a Wimbledon finalist in 2013, will play Julia Glushko in the first-round at Wimbledon in Tuesday’s first match on Centre Court. The tournament’s organizers have chosen her to fill the spot usually reserved for the previous year’s defending champion in Marion Bartoli’s absence.

Hingis began coaching Lisicki at the Australian Open, and started playing doubles with her at Indian Wells. The tandem played four events in total, winning the Miami title, while going 1-3 combined at Indian Wells, Madrid and Rome.

Hingis, eager to keep pursuing her doubles comeback, elected to partner with Vera Zvonareva after being granted a doubles wild card into Wimbledon, while Lisicki decided to concentrate solely on singles.
