RAFAEL Nadal enjoyed the sweet smell of success, but was left complaining about his struggles to hear when on court at Flushing Meadows.
The world No.1 was forced to come from behind to beat Japan's Taro Daniel, 6-1 4-6 4-6 6-2 6-2.
He eventually got his forehand cranking, but was a little cranky after the victory.
With torrential rain lashing the Flushing Meadows site, the Arthur Ashe stadium roof was shut tight above a boisterous crowd of 24,000.
"Being honest, it (the noise) is a little bit too much," said Nadal, who won the 2010 and 2013 US Open crowns.
"The energy and support of the crowd is massive. I enjoy it and I have unforgettable memories from this tournament and this court, because the energy is different from in other places.
"But at the same time, under the roof, it's too much noise. I was not able to hear the ball when hitting.
"I understand it's a show, but under the roof we need to be a little bit more strict about the noise. All the noise stays inside, and this is difficult."
Nadal was at one stage staring down the barrel of joining top seeds Alexander Zverev (four), Grigor Dimitrov (seven), Jo-Wilfried Tsonga (eight), Jack Sock (13), Nick Kyrgios (14) and Tomas Berdych (15) to be knocked out by underdogs.
Roger Federer earlier survived his own scare.
"For me, it's a very important victory. It's true I didn't play very well tonight but at the same time it's true that I am through," Nadal said.
"I need to improve a lot of things but I am here to try to improve every day. I'm going to work tomorrow hard to find better feelings.
"I really believe I can do it much better."
