Marion Bartoli

Former Wimbledon champion Marion Bartoli, 33, is returning to the game to keep her mental demons at bay. She announced her shock return to the women's tour in December, four years after originally calling time on her career. Bartoli retired just months after winning Wimbledon in 2013 — her only grand slam title. She suffered a dramatic weight loss that almost cost her life after contracting a virus in 2016 while also revealing she was abused in a relationship with a former boyfriend.
