Top-seeded Alexander Zverev of Germany beat Matteo Arnaldi of Italy 6-7 (5), 6-3, 6-2 on Thursday night in the third round of the National Bank Open to reach 500 match victories.The 28-year-old Zverev — the 2017 champion — is the first ATP Tour player born in 1990 or later to win 500 matches. He won on clay in Munich in April for his 24th tour title.“I think I started playing better from the baseline. The longer the match went on, I started to find my rhythm a bit,” Zverev said.“It was actually my backhand that was feeling a bit off in the beginning, which is strange. Doesn’t happen very often. But after I found that shot, I was comfortable and I was happy about the level,” he added.ALSO READ | Holger Rune on training with Andre Agassi: Never met a guy who sees tennis that way, found it interestingZverev, ranked third in the world, ended up as the top seed, with top-ranked Jannik Sinner and No. 2 Carlos Alcaraz skipping the hard-court event, which still has a week left.
