But then something wild happened. The Serb began to piece together the necessary ingredients of top-flight players. He trained feverishly, made a few technique changes and gave his diet an overhaul. Djokovic eliminated gluten and most of his irritating antics and ascended to the top of the game. In 2011, he actually won 41 straight matches to start the season.
Since then, Djokovic has been a staple in the back end of majors. He's now in his 23rd career semifinal, tying him for fifth place in the Open era.
Though it should be noted that Djokovic has gone 18 months without a Grand Slam title.
Djokovic next takes on Dimitrov, who handed Murray a thorough beatdown in the quarterfinals. As talented as Dimitrov is, he's still green and moving forward the big stage is going to get even bigger.
Some might say: Advantage, Djoker.
