The German had been a regular member of the world's top 10 without challenging for the game's biggest prizes but she played some outstanding tennis in Melbourne, where she beat Serena Williams in the final, to truly announce her name to the world.
While others who break onto the big scene have often struggled thereafter, Kerber has backed up that performance well.
She reached the final of Wimbledon, where Williams took her revenge, not to mention the Olympics, and such has been her consistency that she came within one win in Cincinnati of usurping the American as world number one.
Instead Kerber lost in the final in Ohio, but her run there proved she is in good nick ahead of another major bid.
Her left-handed serve is a decent weapon and while she's unlikely to hit too many players off the court, her ability to stay in rallies and grind opponents down is notable.
