Didn't see the match, but I did see the highlights on YouTube and you'd think Zverev's camp has got to be worried heading into the AO. He's lost 5 of his last 7 matches going back to the ATP finals. If you go back to his Montreal win he's got 12 losses in his last 22 matches. I included the Hopman Cup but not the Laver Cup.. If you include the Laver Cup, IIRC, he won 2 matches. That would still make him 12-12 in his last 24 matches. NOT a good record with a Slam looming. It's not just the fact that he's losing but the way he's losing. Some of the sets have been straight up blow outs - 6-0, 6-2, 6-1. Is he running out of gas or just losing concentration?
