“USA! USA! USA!” The 6,000 spectators at the US Open came to cheer, and with Donald Young’s rock solid performance on Saturday, they got their chance. He responded by saying to the crowd, “It was 90 percent you guys, and 10 percent me.”

Three hours and twenty-five minutes had passed, but American Donald Young looked a fresh as a player warming up as he headed into the final, victorious game in the fifth set of his third round match against Serbian Viktor Troicki. Within minutes, Young had defeated Troicki 4-6, 0-6, 7-6(3), 6-2, 6-4 on the Grandstand court.

It marked Young’s second comeback from two-sets-to-love down at the US Open. Likewise, it was the third best-of-five match Troicki has lost from two sets up in the past two months. It wasn’t easy for Young, however: the trainer was called after the first two sets and somehow Young summoned up the goods to finish the job. Clearly, the support of the American tennis fans worked.

Coming into the 2015 US Open, Donald Young wasn’t one of the names that the experts bet on for a long run at the Open. But that’s the beauty of these lengthy Grand Slams; unexpected results add to the drama. With the win, Young, ranked 68th in the world, moves on to the Round of 16 and finds himself coming of age as an American tennis professional.

Unfortunately, it might have been the final men’s singles match on the court that has proved lucky for Young. The Grandstand court — one of the most intimate and exciting on the grounds of the US Open — is scheduled to be replaced by next year’s tournament. Ah well, nothing lasts forever… enjoy the moment while you’re young, Mr. Young. We all did today.
