German tennis star Alexander Zverev underlined that he will have to lower the number of his double faults per match after a surprise round-of-16 loss suffered at the Mercedes Cup on Thursday. Zverev, who was seeded at No. 1 in the Stuttgart main draw, didn't make a good start to his 2019 grass campaign as he was beaten by qualifier world No.
170 Dustin Brown 6-4 6-7 (3) 6-3 in his first match on grass this year. World No. 5 Zverev fired 21 aces, won 82 percent of his first serve points but also hit 14 double faults and got broken three times in exactly two hours of action.
Per David Verhoff, Zverev said post-match that he will have to somehow manage the double faults issue and acknowledged that there have been too many double faults from his side in the last few weeks, before adding: "I will work on that."
Zverev will now certainly be extremely motivated to make good result in Halle next week, where he made back-to-back finals in 2016 and 2017 -- but failed win the title on both occasions.
