Serena Williams made her eagerly anticipated return to court at the Mubadala World Tennis Championship (MWTC) on Saturday but her comeback ended in defeat to Jelena Ostapenko. Williams, a 23-time grand slam champion, has not played competitively since winning the Australian Open in January, taking time out from tennis to give birth to her first child. Her lengthy absence and lack of match fitness ultimately told against French Open champion Ostapenko, who won their contest 6-2, 3-6, 10-5 at the International Tennis Stadium at Zayed Sports City in Abu Dhabi. <strong>____________________</strong> <strong>Read more:</strong> <strong>____________________</strong> After a first set where she looked understandably off the pace, Williams fought back to level the match in the second.
