Zverev whips out a running passing shot in Mexico
The German wasn't going to lose this marathon point in Acapulco.
At 6'6", Alexander Zverev is a tall guy. He has incredible arm length to reach shots that other players wouldn't be able to. In Acapulco, he took on Mackenzie McDonald and used his height and reach to it's full advantage in a marathon point.
It seemed like McDonald was in control, but Zverev flicked a shot cross-court past him at the net. It was especially important as Zverev was a game behind in the second set and facing down the barrel of break point. He managed to push it off and win 6-3, 7-5.
