Melbourne, Australia, 14 February 2021 | Leigh Rogers

Winning a Grand Slam title is the ultimate prize in tennis.

Several of our Aussie players in action on day seven at Australian Open 2021 have already achieved this feat.

Sam Stosur is a seven-time Grand Slam champion, winning her titles across singles, doubles and mixed doubles at all four major tournaments.

The 36-year-old made her Grand Slam breakthrough at Australian Open 2005, winning the mixed doubles title with Australian Scott Draper. Playing alongside Matthew Ebden this year, Stosur has her sights set on claiming a second Australian Open mixed doubles title.

Ebden is a former AO mixed doubles champion too. The 33-year-old from Perth scooped the 2013 title with fellow Aussie Jarmila Wolfe.

Other major champions in action today include John Peers, Heath Davidson and Dylan Alcott.

Alcott begins his quest to win a record seventh consecutive Australian Open quad wheelchair singles title, facing off against doubles partner Davidson.

“I love winning Grand Slams, but it’s not the reason I get out of bed. It’s not. It’s to provide opportunities to try and change perceptions,” says Alcott, acknowledging the platform winning major titles creates to influence others.

No matter what their individual motivations may be, all 14 Aussies in action today are determined to experience Grand Slam glory at Australian Open 2021.
