Qualifier Karatsev stuns Dimitrov in order to reach the semifinals in Melbourne

MELBOURNE (Reuters) – Aslan Karatsev continued his sensational series at the Australian Open in the semifinals on Tuesday when he stunned Grigor Dimitrov 2-6 6-4 6-1 6-2 and became the fifth qualifier to reach the last four of the men’s Grand Slam in the open era.

World No. 114 regrouped after opening a set of errors to add the 18th seed to his list of troubled victims in Melbourne Park and set up a clash with Novak Djokovic or Aleksandar Zverev for a place in the final.

Dimitrov looked shocked as the Russian tightened the game and hit the howitzers on the net – stumbling on the serve and reluctantly wandering around the field of Rod Laver Arena in the heat of 30 degrees Celsius.

The 29-year-old Bulgarian took a medical timeout for back treatment after losing the third set, but Karatsev was not denied as he became the lowest-ranked player to reach the Grand Slam semifinals in two decades.
