Serena Williams' dreams of a fairy tale finish to her glittering career were dashed on Saturday as the tennis icon was sent crashing out of the US Open by Australia's Ajla Tomljanovic.The 40-year-old Williams - who last month signalled she planned to retire after the Open - was ousted 7-5, 6-7 (4/7) 6-1 by Tomljanovic in a gruelling 3-hour 5-minute battle.Williams, a sporting and cultural icon who amassed 23 Grand Slam singles titles in her 27-year professional career, poured everything into one last stand in front of a ferociously partisan crowd at the Arthur Ashe Stadium.But the veteran wilted visibly in the decisive third set, wearied by the demands of a heroic second set display that saw her level the match in a tie break.As Tomljanovic raced into a 5-1 lead in the third, Williams summoned every last drop of her fighting spirit to stave off defeat, saving five match points in a marathon seventh game before finally succumbing.Afterwards, Williams saluted the crowd, welling up as Tina Turner's anthem "Simply the Best" belted out around the stands.Asked by an on-court interviewer whether there was any possibility she might yet extend her career, she replied: "I don't think so, but you never know.""It's been a fun ride," she added.
