The first tennis major of the year starts Monday, when the Australian Open commences in Melbourne. Most of the sport’s big stars will be competing over the next two weeks, but will one of them take home a title, or will an up-and-comer upset the field? Here’s a preview on the two singles tournaments.

Men’s Singles

The current “Big Four” in the men’s game (Novak Djokovic, Roger Federer, Rafael Nadal, & Andy Murray) are all in Australia, along with defending champion Stan Wawrinka. Federer, largely regarded as the greatest men’s player of all time, has made four straight semifinals in Melbourne, but can he win another major at 33? Lleyton Hewitt is of the same age, but has not won a major on home soil; his best finish was 10 years ago, losing to Marat Safin in the final. If the Adelaide native can beat Ze Zhang, his next opponent would either be Benjamin Becker or #25 seed Julian Benneteau, with Milos Raonic potentially waiting in the third round. Home fans will also be supporting Nick Kyrgios and Bernard Tomic, the top two Australians in the latest ATP rankings. Wawrinka was regarded as a surprise winner last January; will fans witness another in two weeks?

Women’s Singles

Serena Williams last won the Australian Open in 2010, and could face a tricky second-round clash with Vera Zvonareva, once the #2 player in the world. A few more familiar foes were drawn in the same quarter, notably Sloane Stephens & Victoria Azarenka, who play each other in the first round. As the second seed, Maria Sharapova finds herself at the other end of the bracket, with Eugenie Bouchard, a semifinalist in 2014, potentially waiting in the quarterfinals. Li Na, the defending champion and first Grand Slam singles winner from Asia, retired last fall, but Dominika Cibulkova, the runner-up, is in Serena’s quarter, and is looking for her first major championship. The top Australian in the WTA rankings, Samantha Stosur, opens play against Monica Niculescu, but could face Italian veteran Francesca Schiavone in the following round. Also, can Caroline Wozniacki finally get that elusive first Grand Slam?

Expect a lot of traffic around Melbourne Park, with the MCG, one of the venues for next month’s Cricket World Cup, located a short walk away. The next two weeks should say a lot about how the 2015 tennis season will unfold, but all indications say it will be a fun one.
