Just as in the first round against Indian Sumit Nagal, five-time US Open champion Federer dropped the first set under the roof. Matches on the other courses were stopped because it rained in New York.

- I had a lot of respect for Dzumhur and had a hard time in the first set and the beginning of the second. Then I could improve the game. It was important for me to think positive thoughts and focus on concentration. I managed to defend my serve after the careless first set, ”Federer says.

The 38-year-old served heavily and decided when Dzumhur hit the return line over the baseline and the match was over after 2.21. Federer relied on the serve, putting in 16 aces and getting 81 percent of the first serve.
