Karatsev after winning the match said that it was an unbelievable feeling. It was unbelievable because his career had hugely been compromised due to an injury. “It was tough at the beginning for me to hold my nerves, but I tried to find a way to play,” he added.

He is the lowest-ranked sportsperson, at 114, to make it to the semi final at a Grand Slam since 2001, when Goran Ivanisevic won ranked at 125.

After a five-setter with Felix Auger-Aliassime in round four, Karatsev had an easier ride against Dimitrov who was wincing with pain from the third set.
