Tennis LIVE: Shanghai Masters star refuses to retire as Brit ranked No.170 gets huge upset

Britain's Sonay Kartal has just earned her biggest win of the season, even though she's spent six months sidelined by a back injury. Ranked down at No. 170 in the world and playing just the third tournament of her comeback after the Billie Jean King Cup Finals and the China Open, she's stunned ninth seed Belinda Bencic 6-0 7-5 in the second round of the Wuhan Open. After bagelling the former Olympic champion in the first set, Kartal won a topsy-turvy second set which saw five breaks of serve.
