The German outpointed Coric in four sets and will attempt to reach the first Grand Slam final of his career on Thursday.
German Alexander Zverev, the fifth seed, got off to a bad start and reached the US Open semifinals on Tuesday by defeating the Croatian in a tough game Borna Coric.
Zverev, number 7 of the ATP, beat Coric (32nd) by 1-6, 7-6 (7-5), 7-6 (7-1) and 6-3 in three hours and 24 minutes at the stadium Arthur Ashe, the principal of Flushing Meadows.
The German, who also reached the semifinals of the last Australian Open, will now face the winner of Tuesday’s cross between the Spanish Pablo Carreño and Canadian Denis Shapovalov.
Without Djokovic, Federer and Nadal, the three absolute dominators of tennis in the last 16 years, the United States Open started its quarterfinals on Tuesday with eight contenders for the first Grand Slam of their careers.
Zverev, one of the strongest tennis players during the first week of competition, has made no secret that he wants to take advantage of Sunday’s disqualification of Djokovic to stand in the first Grand Slam final of his career at 23 years old.
“There will be a new Grand Slam champion. That’s all I know right now,” Zverev said after the expulsion of the world number one. “Now is the time that it gets really interesting.”
The Spanish will compete in the other quarterfinal crossing on Tuesday Pablo Carreño, who advanced to this round after Djokovic’s surprise disqualification for accidentally hitting a lineswoman when play was stopped.
The Spaniard, the oldest of the group at 29 years old, has four individual titles and three in doubles in his record, the last of which was won in the Masters 1000 de Cincinnati in the week prior to the US Open with Australian Alex de Miñaur, another of those classified for the quarterfinals.
Carreño’s rival will be the Canadian Denis Shapovalov, 21, who beat seventh-seeded Belgian David Goffin in the round of 16.
The other two quarterfinals will be played on Wednesday by Austrian Dominic Thiem (2nd seed) and Russian Daniil Medvedev (3rd), the only two from this group to have reached a Grand Slam final.
Thiem, the only surviving member with Carreño who is over 25, will face De Miñaur (28th ATP) and Medvedev against his compatriot Andrey Rublev (14°).
