Dimitrov had his own missed opportunities in the beginning stages, letting slip seven set points in the opener, one of which he missed by dumping a routine backhand volley in the net. But that did not discourage the Bulgarian from moving forward, instead only fuelling his determination. 

He took a more aggressive baseline position in the second set and converted all eight of his net points.

Playing with great variety by mixing backhand slices with his trademark one-hander, Dimitrov began to dictate rallies. He did not drop a point behind in his first serve (11/11) in the second set.

Trailing 0-3 in the decider, Dimitrov mounted another comeback to become the fifth man to reach multiple Miami semi-finals after turning 30 (Andre Agassi, Jimmy Connors, Roger Federer, John Isner). He improved to 12-1 in deciding-set matches at the ATP Masters 1000 event in south Florida.

Up next for the 14th seed will be six-time champion Novak Djokovic or American Sebastian Korda.

Having arrived in Miami defending his finalist showing from last year, Dimitrov’s run to the last four has him at 18 in the ATP Live Rankings.
