Zverev struggles with diabetes management in loss to Fritz at Halle

Summary

Alexander Zverev's journey at the Terra Wortmann Open ended in the semifinals, where he lost to Taylor Fritz.

Despite battling back in the first set, he ultimately fell 6-7(4), 6-4, 7-5. Post-match, Zverev acknowledged the difficulties caused by his diabetes management but expressed optimism about his form heading into Wimbledon. Fritz is set to compete against Frances Tiafoe in the final of the ATP 500 event.
