A first-round match on Thursday at the Huafa Properties Zhuhai Championships featured one of the most interesting endings to a match in recent memory.

After Mackenzie McDonald polished off a 6-4, 6-7(3), 6-3 victory over #NextGenATP Chinese star Shang Juncheng, who was struggling physically with cramp, the American jogged to Shang’s side of the court. McDonald put Shang on his back and carried him to his chair.

“I knew he was struggling so I ran to him to shake his hand,” McDonald told ATPTour.com. “He said, ‘Good match’, and he said, ‘Can you help me to the bench?’ I said, ‘Hop on’. So he jumped on my back and I carried him over to the bench and he said, ‘Good match, man.’”

The clip of the competitors enjoying a light-hearted moment after a tough battle quickly went viral on social media. McDonald needed two hours and 36 minutes to win the match, but just seconds to earn plenty of fans around the world.

The sixth seed will face Belgian Kimmer Coppejans for a place in the quarter-finals.
