Sam Stosur, the 2011 US Open champion, is currently ranked at number 17 in the world, and the Australian number one found her success on the doubles court as a multiple-time Grand Slam champion and former world number one until she transitioned to play solely on the singles court.
The 32-year-old has been ranked as high as four in the world and before she won her first Grand Slam singles title at the US Open, she reached the French Open final a year prior losing to Francesca Schiavone, and in 2016, she reached the semifinals in Paris once again.
Notable results to date
The Australian number one has played plenty of tennis in 2016 and she boasts a 29-18 win-loss record, and as usual, Stosur struggles to perform well in her home country, and especially at the Australian Open where she has reached the fourth round twice in 2006 and 2010.
Following disappointing results in Brisbane and Sydney, the former top-five player suffered a first round defeat at the Australian Open at the hands of Kristyna Pliskova.
However, Stosur's fortunes improved at the BNP Paribas Open in Indian Wells, as she reached the fourth round there losing to two-time Australian Open champion Victoria Azarenka in three sets, and the Belorussian went on to win the title.
After receiving a bye in Miami, Stosur failed to back up her good week in the Californian Desert, as she suffered a three set defeat to Julia Goerges in their second round meeting.
Clay has been Stosur's most successful surface to play on and once again, the Australian had a very good clay court season. The 2011 US Open champion reached the final in Prague losing to Lucie Safarova in three sets.
The Australian backed up her run in Prague with a semifinal run at the Premier Mandatory event at the Mutua Madrid Open which is played at altitude and aids Stosur's game perfectly, and she only gained two games in her defeat to eventual champion Simona Halep.
Once again, Stosur failed to deliver at the following tournament as she lost to two-time Grand Slam champion Svetlana Kuznetsova in the second round in Rome.
Stosur announced that the French Open was going to be the last tournament with her long-time coach David Taylor, and it was a successful one for the duo as the Aussie reached her fourth semifinal in Paris in eight years.
The world number 17 recorded wins over the last two French Open finalists, Lucie Safarova and Simona Halep, in the third and fourth rounds respectively but was soundly beaten by eventual champion Garbine Muguruza in the semifinals.
Stosur had an abrupt grass court season, and grass has historically been the worst surface for the Australian in singles although she has made three doubles finals and won two mixed doubles title at Wimbledon.
The third round on three occasions in 2009, 2013, 2015 has been the furthest Stosur has been able to reach Wimbledon, and this year she suffered a second round exit to 2013 finalist Sabine Lisicki with whom she made the doubles final in 2011.
Best hard court results leading to US Open
Following a short grass court campaign, Stosur returned to hard courts as she was competing at the Rio Olympics for her country, and was preparing for the US Open.
At the Bank of the West Classic in Stanford, Stosur suffered a disappointing quarterfinal defeat to Jessica Pegula and lost to Daria Kasatkina in the second round of the Coupe Rogers in Montreal.
The 2011 US Open champion competed in Rio in all three disciplines and she lost to eventual silver medalist Angelique Kerber in the third round and suffered a first round exit with Daria Gavrilova to eventual silver medalists, Timea Bacsinszky and Martina Hingis, and she paired up with John Peers in the mixed doubles but they lost in the first round to Sania Mirza and Rohan Bopanna.
At the Western and Southern Open, Stosur received a bye but she had a tough opener with Barbora Strycova, who left Rio with a bronze medal in the doubles event, and she lost in straight sets.
Best US Open result
In terms of results, the French Open has been Stosur's most consistent Grand Slam tournament, however, the US Open will always be her most successful as she won the title in 2011 defeating three-time champion Serena Williams in the final.
Stosur was seeded ninth in her title run in New York, and her route to the title began with straight sets victories over Sofia Arvidsson and CoCo Vandeweghe.
In the third round, Stosur had a battle with 24th seed Nadia Petrova and she was victorious 7-6, 6-7, 7-5, and this was followed by another tussle in the fourth round with Petrova's 25th seeded compatriot, Maria Kirilenko, which required three sets for Stosur to reach her second consecutive quarterfinal in New York.
In the quarterfinals, Stosur faced a Russian for the third consecutive match and it was with two-time Grand Slam finalist and second seed Vera Zvonareva, which Stosur won 6-3, 6-3 to reach her third Grand Slam semifinal.
Stosur was paired with future Australian Open champion Angelique Kerber in the semifinals, and the Australian number one was victorious in three sets to reach her second Grand Slam singles final.
In the final, Stosur defeated Serena Williams who was seeded 28th as she was coming back from a life-threatening pulmonary embolism in 2011 and it was a 6-2, 6-3 victory for the Australian.
Stosur's other best finishes in New York were quarterfinal finishes in 2010, and once again in 2012 when her title defence was ended in a three-set tussle with two-time finalist Victoria Azarenka.
The Australian has found success at the US Open in the doubles as she won the title in 2005 with Lisa Raymond, and reached the final in 2009 losing to Cara Black and Liezel Huber.
How Stosur's game translates to the surface
Stosur is very good at net due to her days in playing in doubles, and is a very good volleyer, and can do a drive volley which is difficult to do.
The Australian's serve is a kick serve which works perfectly on clay, and can be effective on hard courts as well. She also possesses a good forehand and likes to slice, however, her backhand is not as strong and can be targeted.
Nonetheless, Stosur remains a threat on hard courts and at the US Open, and if the Australian can remain motivated and not become too erratic, she has a very good chance of going far in New York again.
