Alexander Zverev slammed down 18 aces en route a demolition of Alejandro Davidovich Fokina 6-2 6-2 6-1 in the fourth round of the United States Open on Sunday in New York.
After an early break for the 2-1 lead, the 23-year-old German never let his Spanish opponent get a foothold in the match.
He produced 39 winners and dropped just one service game during a ruthless performance.
Davidovich Fokina grabbed a 2-0 lead in the second set but the advantage was shortlived as Zverev broke back before racing away with the set.
He sealed it with an ace.
The Spaniard barely had a chance to make an impact on the world number seven’s serve, the fastest clocking at 139 mph, just shy of his personal record of 142 mph.
Davidovich Fokina, who took a medical time out to treat a foot problem, tried to rattle Zverev by attempting some drop shots.
But the fleet-footed fifth seed moved nimbly around the court.
“I’m in the quarter-finals and that can only be a good thing,” said Zverev, who reached the Australian Open semi-finals earlier this year.
“I’ve been waiting for this moment for six months.”
