#4 Grigor Dimitrov
The 25-year-old from Bulgaria has had a dream start to the season, winning the ATP 250 Brisbane International last week. This was his first ATP title since winning the Queen's Club Championships in 2014. It will act as a huge morale booster to him for the rest of the season.
Dimitrov has always been one player who has been over-pressurized by the weight of expectations, having names like "Baby Federer" dished out to him at a very young age. His perfect start to the season will definitely help him in his quest to finally realise the extraordinary potential that he possesses.
In Brisbane last week, he beat three top-10 players, namely Thiem, Raonic and Nishikori, back-to-back, on his way to the title. To put that achievement into context, he had three top 10 wins in all of 2016.
A little bit of time away from the game has done him a world of good. “I played motor bikes, we played cars, basketball. Every time I was going to bed, I was, like, Wow, that feels so good," said Dimitrov, when quizzed about his sudden rich vein of form in Melbourne.
His fans would be hoping that he carries this same state of mind 850 miles down south to Melbourne.
