Djokovic’s long-awaited return to the top of the heap came in early 2011 at the Australian Open, three years after grabbing his first Slam victory at the same tournament. Djokovic was simply unstoppable in this one, losing just one set (in the second round) during his seven-match run to the title. He put an exclamation point on the achievement with dominant wins over world-class opponents like Tomas Berdych (No. 6, quarters), Federer (No. 2, semis), and Murray (No. 5, final). The final was particularly lopsided, as Djokovic came out on top 6–4, 6–2, 6–3.
