The world No. 1 and three-time Grand Slam champion lags behind her contemporaries in endorsements despite standing atop her sport

The world No. 1 came agonizingly close to winning a third straight title Down Under, but leaves Melbourne with plenty of positives despite a runner-up finish to Madison Keys.

Jannik Sinner joined some of tennis' greatest legends with another stellar performance in the Australian Open final.

Jannik Sinner and the Australian Open have in common the fact that the only thing that can beat them is to let success go to their heads.

Alexander Zverev is into the Australian Open final after Novak Djokovic retired hurt after losing the first set of his clash with the German. The German had taken a tie-break (7-5) when the Serbian called it quits, having struggled with a muscular problem in his left leg. Djokovic was booed as he limped off court.

There’s nothing quite like a sporting curse, and this time it seems a legendary actor might have wreaked havoc at the Australian Open.
