German tennis star Alexander Zverev has pulled out of the Halle doubles due to a knee injury. The 22-year-old and his brother Mischa Zverev gave a walkover to Ben McLachlan and Jan-Lennard Struff. On Monday, second-seeded Zverev opened his singles campaign in Halle.
The German survived a tricky first round clash as he claimed a tight straight-set win over Dutch Robin Haase 6-4 7-5. The 22-year-old saved a set point in the second set as he recovered from a 5-2 deficit to steal the set.
The Zverev brothers were expected to make their fifth appearance as a team on the grass courts of Halle this year. The Zverevs came close to winning it all at the Halle event in 2017 and 2018 but both times fell just short as they ended runners-up.
The Zverev brothers were replaced in Halle by Matt Ebden and Denis Kudla, who ended up losing to McLachlan and Struff in straight sets 6-4 6-4. Meanwhile, it remains to be seen will world No. 5 Zverev also withdraw from the singles event. Should Zverev continue his singles campaign, he would play against American Steve Johnson in the round-of-16.
