In the final, American opposition awaits, either Frances Tiafoe or Ben Shelton.
"Hopefully I can make sure the American dream doesn't come true on Sunday," Zverev said.
I can't wait for Sunday. It's going to be incredibly special. Frances and Ben are crowd favourites here in New York.
In Jannik Sinner's absence, world number two Zverev is the top seed at the US Open. Should he win the tournament, it will be his second Grand Slam title and his first at the US Open.
