Rafael Nadal beat Vasek Pospisil 6-3, 6-4, 6-2 and reached the third round at the US Open.
His only hiccup came in the second set, when he dropped his serve to fall 2-4 down.
"The conditions are tough," Nadal said. "It was important to start very well with that break. To win in straight sets is always very positive, especially in these conditions. It's almost midnight, very happy about the victory."
