Roger Federer admitted he was delighted to produce some “great tennis” as he reached the fourth round of the US Open at the expense of Marcel Granollers.

The Spaniard took the first set but Federer recovered to prevail in the thunderstorm-affected clash at Flushing Meadows.

Federer, 3.20 to win the US Open, had not been tested in his first two games in the tournament but that soon changed as he failed to deliver early on.

The 33-year-old eventually won 4-6 6-1 6-1 6-1 but the break in play seemed to disrupt Granollers’ rhythm. Federer stepped up his game after the downpour and his opponent didn’t win another game until the third set when it was 3-0.

Federer eventually sealed the win inside an hour and 58 minutes and he admitted after the match the break helped him recover from early errors.

He said: “I enjoyed it. I thought it was a good match and I’m happy I was able to come back and turn it around. Marcel started really on fire. The break helped me and I came out and played some great tennis.

“I felt he was in trouble, also. It’s not very often that him and me are tired like this after two hours.”

Elsewhere in the men’s draw, Grigor Dimitrov also bounced back from a set down to beat David Goffin in four sets.

Sixth seed Tomas Berydch beat Russian Teymuraz Gabashvili 6-3 6-3 6-4 and he will play Dominic Thiem after he overcame Feliciano Lopez 6-4 6-2 6-3.
