Karatsev was the surprise at the recent Australian Open, where he was only killed in the semi-finals against Djokovic. “This is the best victory of my career,” said the Russian on Saturday after the game. “In such a match you have to give everything, because it is like playing against a wall.”
In his second ATP final, Karatsev will take on the winner of the game between the Japanese Taro Daniel (ATP 126) and the Italian Matteo Berrettini (ATP 10). Earlier this year, the Russian took the overall victory in Dubai.
The Serbia Open is back on the ATP calendar for the first time since 2012. Djokovic, who was killed in the eighth finals of the Masters 1,000 tournament in Monte Carlo last week, won the tournament in his home country in 2009 and 2011.
