( CNN ) -- Australia 's Samantha Stosur produced one of the biggest shocks in U.S. Open final history , beating Serena Williams in straight sets at Flushing Meadows to secure her first Grand Slam success . Williams , bidding for her fourth U.S. Open crown , had gone into the match as a hot favorite despite a troubled year blighted by injury and serious illness . But Stosur never allowed the American , who was cheered on by a patriotic New York crowd on the 10th anniversary of 9/11 , to settle -- claiming a spectacular 6-2 6-3 triumph in 73 minutes , as Williams lost her cool following a contentious umpiring decision . `` I had one of my best days and I 'm very fortunate that I had it on this stage in New York , '' Stosur said after the match . `` Ever since I started playing , it was a dream of mine to be here one day , and now my dream has come true . '' Stosur breaks Aussie drought . Stosur , whose run to the final included a marathon third-round victory over Nadia Petrova that lasted a tournament record three hours and 16 minutes , continued : `` Serena , you are a fantastic player , great champion and have done wonders for our sport . `` Thanks to everyone back home for supporting me . All my friends , family and everyone else , thanks so much for supporting me . I look forward to coming back home . '' Although she was only seeded 28th , Williams came into the tournament bang in form after winning two warm-up events -- including victory over Stosur in the final of the Rogers Cup in Toronto . And the American was mightily impressive in dismantling world number one Caroline Wozniacki in the semifinals , while ninth seed Stosur struggled to beat unseeded German Angelique Kerber in three sets in the other semi . With emotions high among New Yorkers , on a poignant day for the city , a Williams win looked set to provide the United States with a fitting end to a difficult occasion . But Stosur , whose only previous Grand Slam final appearance came last year when she lost the French Open to Francesca Schiavone , did not read the script , dominating the opening set against the 13-time Grand Slam champion , who had reached this stage without dropping a set in the tournament . Stosur broke Williams to lead 2-1 and then won the last 12 point of the set in an impressive display of pace and power . Then came the talking point of the match . Williams had already saved one break point in the first game of the second set . However , on the second break point , the American shouted `` come on '' as she unleashed a fierce forehand before Stosur had reached the ball . Umpire Eva Asdaraki immediately penalized Williams for `` intentional hindrance , '' and the point and the game went to Stosur . Williams reacted angrily to the decision and was then given a code violation for verbal abuse . The American immediately broke back and then held serve but continued to berate the umpire at the changeover , as her composure ebbed away . `` Do n't even look at me -- If I see you in the corridor do n't even walk past me , '' shouted the 29-year-old . `` A code violation for expressing my opinion ? , we 're in America -- you 're unattractive inside '' Stosur then broke serve to take a 4-3 lead and broke Williams again to clinch a famous victory -- becoming the first Australian women 's winner at Flushing Meadows since Margaret Court in 1973 . When asked about the incident after the match , Williams said : `` I was just doing my best . I hit a winner but I guess it did n't count . It would n't have mattered anyway because Sam played really well and she is a great player . '' She continued : `` Six months ago I did n't think I would be standing here . I did n't think I would even be standing , let alone be here . '' Stosur 's victory means she joins Li Na and Petra Kvitova as first time Grand Slam winners this year .
