The top two seeds remain on course for their scheduled semi-final meeting but both Roger Federer and Rafa Nadal suffered some scary moments before progressing into the third round.
It's true that I didn't play very well tonight but it's also true that I'm through to the next round Rafa Nadal
Earlier in the day Federer survived his second five-set match at this year’s US Open while Nadal, playing in the evening, was forced to recover from a set down by a gritty Japanese Taro Daniel before claiming his place 4-6 6-3 6-2 6-2.
It took him nearly three hours to book his place and the Spaniard struggled to find his form during the first set but he took charge in the second after recovering from an early break by speeding up the game and imposing himself on his opponent, finishing the match with 40 winners against 35 unforced errors.
Following the two-hour and 53-minute encounter, Nadal commented during his on-court interview on the Arthur Ashe Stadium: “All the matches are difficult, especially here where everyone wants to play their best.
“It’s true that I didn’t play very well tonight but it’s also true that I’m through to the next round.
“I am here to improve every day. I believe I can do it much better and I really feel I am going to do it much better,” Nadal added
