The Olympic champion from Tokyo reached the victory against the 46th tennis player in the world after a little more than two hours of play, and thus extended his winning streak to 16 matches.
The tennis players exchanged a break in the first set, so the winner of that part of the game was decided in a tie.break, which was won by Zverev with 8: 6. Previously, Harris also missed one set ball.
After that, the German took control, one break was enough for him to win in the second set, to take the lead with a big 4.0 in the third and easily bring the match to an end.
“He served amazingly in the first set, so I didn’t have many chances. Somehow I managed to win the first set and that relaxed me a bit,” said last year’s US Open finalist.
Zverev will fight for a place in the finals of the US Open with the winner of the quarterfinals, in which the best tennis player in the world, Novak Djokovic, and the Italian Mateo Beretini will meet.
