Celebrating the win, it was Fritz’s girlfriend, Morgan Riddle, who had the last word. Riddle appeared to mock Zverev when she posted on her Instagram Stories.

"When ur man wins 4 the girls," she wrote referencing allegations that he assaulted a woman in 2020.

Riddle also wrote in another post, "cheer loud ladies."

Zverev settled the domestic abuse case after reaching an out-of-court settlement with his former partner, who made the accusations. A German court ended the trial back in June. He agreed to pay fines of around $162,000 to the state and about $54,000 to charity.

Prosecutors said Zverev pushed the woman against a wall and choked her during an argument. Zverev maintained his innocence.

In the match against Fritz, Zverev appeared to take issue with the cheering coming from his opponent’s box in the fifth set. He said "they were a bit over the top."

Zverev also acknowledged he was playing with a knee injury.

"I was playing on one leg," Zverev said. "It was fairly obvious that I wasn’t 100% today, right? I wasn’t moving, really, the entire match. I wasn’t running for drop shots. If I was running for a drop shot, I was limping there more than running."
