UPDATE: Alexander Zverev defeated Federico Delbonis, 6-4, 7-6 (2), to book an appointment with Filip Krajinovic. Watch the match-point highlight above.

World No. 5 Alexander Zverev hit the ground running in Hamburg, dispatching Nicolas Jarry—champion in Bastad last week—6-4, 6-2 to set up a clash with World No. 67 Federico Delbonis. Zverev, who is 1-0 against Delbonis, defeated the Argentine en route to his lone title this year in Geneva.

Interestingly, coach Ivan Lendl did not join Zverev in Hamburg, raising further questions about the future of their partnership—particularly after the young German practically accused his new coach ofbeing unprofessional.

“Sometimes we go to the tennis court, the training is two hours long, and for half-an-hour he stands with his back to me talking about the way he played golf the morning before," Zverev said.

If Zverev can focus on his tennis instead of other recent turmoil surrounding his team, he should have no issues with the heavy hitting lefty Delbonis’ trusty cross court forehand will funnel plenty of shots to the rock-solid Zverev backhand. The Delbonis serve will need to be locked in from the start in order to cope with Zverev's rangy returns.

Perhaps the absence of Lendl will provide Zverev with an extra surge of motivation at his home tournament, but he should win this match either way.
