In 34 minutes Sinner was up a set and showing why he is a Grand Slam champion. He continued his forehand passing precision to instantly break in the second set.
Down 1-2, Dimitrov unleashed his most penetrating backhand of the match, a down-the-line gem to chalk up deuce. Sinner neutralised any hint of trouble with two quick-fire aces and rapidly posted a two set lead.
‘The Fox’ was wily on pretty much every point, hanging in with patient play to force Dimitrov to produce spectacular shots. The 33-year-old did just that, scorching a forehand winner at 1-2 for his first break opportunity of the match.
Sinner escaped that time, but Dimitrov was digging in his heels. With the Italian serving for the match at 5-4, the world No.10 clattered another forehand for 5-5.
But like most Grand Slam champions, Sinner found another level. Into the tie-break and the 22-year-old slid to his left to direct an open-stance backhand down the line to cap a memorable day.
