Alexander Zverev was unable to pull off another five-set victory at the US Open as an error-strewn performance condemned him to a fourth-round loss to Diego Schwartzman marked by an umpiring controversy.

Zverev won the first set at Arthur Ashe Stadium in straightforward fashion but fell victim to a tremendous comeback from Schwartzman, who progressed to his second quarter-final in three years at Flushing Meadows.

Schwartzman came through 3-6 6-2 6-4 6-3 in over three hours, demonstrating devastating power off both wings and great touch at the net in a superb showing.

By contrast, Zverev's display was well below the standard that has seen him become established as one of the best young talents on the ATP Tour.

The 22-year-old has yet to make the breakthrough most expect of him, and his defeat on Monday owed to 65 unforced errors and 17 double faults.

Zverev was also docked a point that cost him the seventh game of the fourth set, allowing Schwartzman to go up 5-2, after being assessed a second code violation, the German left furious having claimed he did not hear the first.

Schwartzman wrapped up the win with a rasping forehand and will play either Rafael Nadal or Marin Cilic next.

On the prospect of playing Nadal, he told ESPN: "He's my friend, it's always great to play against him in quarter-finals of grand slams."

- Berettini overcomes Rublev -

Matteo Berrettini of Italy advanced to his first Grand Slam quarterfinal by beating Russia's Andrey Rublev 6-1, 6-4, 7-6(6) at the U.S. Open on Monday.

Berrettini, seeded 24th, made use of his big forehand throughout the match, hitting 17 forehand winners on the Louis Armstrong Stadium court.

"My weapons were really good today," said Berrettini, who hit a total of 37 winners. "I was mixing up my tennis."

The 43rd-ranked Rublev, with wins against Swiss pair Roger Federer and Stan Wawrinka in Cincinnati last month, went into Monday's match as the slight favorite.

But the Russian struggled with his first serve through most of the match, managing to get only 56% of first serves in and losing 67% of those he landed.

Berrettini faces the winner of Monday's later match between France's 13th seed Gael Monfils and Pablo Andujar of Spain.
