Zverev is trying to become Germany’s first Grand Slam champion since Boris Becker at the 1996 Australian Open. He will face either No. 2 seed Dominic Thiem or No. 3 Daniil Medvedev, the 2019 runner-up.
Carreno Busta, the No. 20 seed, lost in the US Open semifinals for the second time in four years.
Zverev served 24 aces against Carreno Busta, the second time during the US Open he’s had 24 aces, according to ESPN Stats & Information. Zverev has hit 18 or more aces in five of his six US Open matches.
Zverev has dropped six sets on his way to reaching the final. He’s the first man to concede that many sets en route to reaching the US Open final since Andre Agassi dropped seven sets in 2005 before losing to Roger Federer in the final.
The last German to reach a Grand Slam final was Rainer Schuettler at the 2003 Australian Open, where he lost to Andre Agassi. The last German to reach the US Open final was Michael Stich in 1994, where he lost to Agassi.
