Sinner makes short work of Dimitrov in the first set!

So far, it's been a disappointing clash. Faced with a confident Dimitrov, the Italian has so far gone it alone, winning the first set very comfortably (6-2 in 36 minutes).

Faced with a very shaky Bulgarian, the world number 2 produced a near-perfect performance. Very solid in the exchange, he made his opponent suffer enormously, finding plenty of length.

Much better than in his previous matches, Sinner is making his mark. Dimitrov is going to have to wake up and offer a lot more if he doesn't want to go out the back door without having had a chance.
