Martina Hingis's glittering career came to a sudden end on Saturday when she suffered a shock doubles defeat at the WTA Finals — her last tournament before retiring. Hingis and Taiwan's Chan Yung-Jan, the world's top pairing and reigning US Open champions, were beaten by third-ranked Timea Babos and Andrea Hlavackova 6-4, 7-6 (7/5) in the Singapore semi-finals. It ended a 19-match winning streak for Hingis and Chan — and halted one of the great careers in tennis.
