Williams finishing runner-up at a top tournament is rare. The 21-time grand slam singles winner had won her last eight major finals, which shows just how special Kerber's achievement was. PETER PARKS/AFP/AFP/Getty Images

Did Kerber have time to soak up her Melbourne success, maybe take a few weeks off? Nope. She was back playing a week later in the Fed Cup for Germany. However, her team lost 3-2 to Switzerland in Leipzig. Dennis Grombkowski/Bongarts/Bongarts/Getty Images
