Zverev has hit peak form just in time for the US Open final. The German started the tournament with two five-setters, but has since picked up the pace. As in the last two matches, tonight's quarter-final against world No. 70 van de Zandschulp was won in straight sets (6-2, 7-5, 6-1).
In Jannik Sinner's absence, Zverev is the top seed at Flushing Meadows. Should he win the tournament, it will be his second Grand Slam title and his first at the US Open.
In the semi-finals, Russian Karen Chatjanov, ranked 50th in the world, awaits.
