UPDATE—Alexander Zverev has split with coach Ivan Lendl:



HAMBURG, Germany (AP) — Second-seeded Alexander Zverev pleased his home crowd by beating Federico Delbonis on Thursday to reach the quarterfinals of the Hamburg European Open.

Zverev rallied from 3-0 down in the second set to defeat the Argentine 6-4, 7-6 (2).

Delbonis had hoped to take it to a third set after breaking to love when Zverev was serving for the match but the German went on to win the tiebreaker.

Zverev is playing at his home ATP 500 tournament for the first time since 2016, when he exited in the first round.

He will next meet Serbia's Filip Krajinovic who hit 12 aces in a 6-7 (6), 7-5, 6-1 win over 2016 champion Martin Klizan.

Third-seeded Fabio Fognini is also through after saving a set point in the opening set and going on to beat Rudolf Molleker 7-5, 6-4.

The Italian will face Pablo Carreno Busta of Spain, who beat seventh-seeded Jan-Lennard Struff 6-1, 7-6 (4).
