MUNICH: German world number three Alexander Zverev is through to the quarter-finals of the ATP event in Munich after cruising to a straight-sets win over Daniel Altmaier on Wednesday.

Zverev, the top seed at a tournament he won in 2017 and 2018, won 6-3, 6-2 to reach his 99th quarter-final on the ATP tour.

"He makes it complicated. He has beaten lots of top players before. He's beaten (Jannik) Sinner, he's beaten me before, so he knows how to make it complicated," said Zverev.

"I'm extremely happy with the win and looking forward to the next match." Zverev has not made it past the quarters on the Munich clay since last winning the tournament seven years ago. He has also struggled for form since losing the Australian Open final in January.

In six tournaments since losing to Sinner at Melbourne Park, Zverev has been unable to get past the quarter-finals.

A defeat to Matteo Berrettini in his first match at the Monte Carlo Masters last week cost Zverev a shot at the world number one ranking held by Sinner. Zverev then dropped down from second after Carlos Alcaraz won the title in the principality.
