Australian Open 2014: Sky Sports takes a look at some outside picks for the tournament

Sky Sports takes a look at some outside picks who could shake things up at the 2014 Australian Open.

Stanislas Wawrinka (Sky Bet odds: 33/1) Stan could be 'The Man' this year following a stellar 2013. He is without doubt one of the outside contenders who could break the monopoly of the top-ranked players at this year's grand slams. Wawrinka won the Roland Garros junior title in 2003 and hasn't looked back since. He is notable for giving opponents a hard game on any surface. He battled Novak Djokovic in two very memorable matches last year and claimed just his fourth ATP title of his career by winning the Portugal Open in Oeiras. He also reached a further three finals, but lost in 's-Hertogenbosch, Madrid and Buenos Aires. Magnus Norman - runner-up at the 2000 French Open and former world No 2 - was hired to mentor the player on a trial basis, but the Swede's knowledge paid immediate dividends as the 28-year-old climbed back into the top-10 as well as reaching the World Tour Finals for the first time in his career. Norman is now expected to commit long-term to Wawrinka, who possesses one of the best single-handed backhands on tour. And after living in the shadow of Roger Federer for so long, it would be no surprise to see him take the mantle as the Swiss No 1 in 2014. Jo-Wilfried Tsonga (50/1) The Frenchman will be aiming for a healthy 2014 after being blighted by injury last season. Tsonga's summer came to a premature end when he was forced out of Wimbledon and the US Open after suffering an injury to his left knee. The 10th seed did reach the quarter-finals of the Australian Open before going down to Roger Federer in five sets. He then went one better at Roland Garros where he was attempting to become the first Frenchman to reach the French Open final since Henri Leconte in 1988. After gaining sweet revenge over Federer in the last-eight, his Parisian dream came to a shuddering halt with a massively disappointing straight sets defeat at the hands of David Ferrer. He did add to his nine ATP titles with victory on home soil in Marseille, but lost to compatriot Gilles Simon in the Metz final. In October, Tsonga hired Nicolas Escude and Thierry Ascione as his new coaching team, replacing Roger Rasheed. The 28-year-old has been in the top 10 for several years but has yet to win one of the four grand slam titles. Could this be his time? John Isner (125/1) Marathon man Isner is currently the highest-ranked male American tennis player, having moved from world No 22 to a career high 14, winning two ATP titles. After pulling out of the Australian Open due to a knee injury the 28-year-old 6ft 9in player from Greensboro, North Carolina captured his first title on clay in Houston by firing a record 64 aces en route to the title. He picked up his second in Atlanta after overcoming South African Kevin Anderson in three tie-break sets. Isner has traditionally saved his best for the home crowd with 14 of his 16 career ATP Tour final appearances coming in the States. The big-hitting Isner has a serve which regularly tops 140mph, but he is most famous for his three day first-round victory against Frenchman Nicolas Mahut at Wimbledon which lasted an incredible 11 hours and five minutes. In that match he served an astonishing 113 aces, before winning 70-68 in the fifth set. Isner led the ATP in aces for the third time in four years in 2013, finishing with 979, but his best major performance to date has been reaching the quarter-finals at the 2011 US Open. Isner has clear tactics ahead of the Australian Open. "I'm going to try to have an aggressive mindset and stick with it." If he does, we could witness a resurgent Isner going far Down Under.
