Nadal has never gone out in the first round, and the match during the night against Wednesday, Swedish time, was no exception.
The opposition was Australian John Millman, ranked 60th. Millman has the experience of defeating big players, including beating Roger Federer in last year's US Open edition.
So it was a Nadal who had respect for his opponent when he stepped out on the centercourt.
"He showed last year what he can do when he plays well," Nadal said after the match, according to Reuters.
"Played well"
But in the meeting, world mad Nadal wasted no time, but defeated Millman in straight sets, 6-3, 6-2, 6-2, in a match where the Spaniard gained more momentum as it progressed.
"To be the first match I think I played a good match, beat good backhands, maybe a few more mistakes with the forehand than usual, but generally I'm happy with the start," Nadal said.
In the next round another Australian, Thanasi Kokkinakis, is waiting.
However, the eighth-ranked Greek Stefanos Tsitsipas has finished well, after losing to Russian newcomer Andreij Rublev, with the numbers 6–4, 6–7, 7–6, 7–5.
Controversial match
The match was also surrounded by controversy, as Tsitsipas was warned of unauthorized coaching. When asked later in the match to quit, it broke for him, and he yelled at the French referee.
-You are the worst! For some reason you have something against me, I don't know what. Because you're probably French. And you are all quirky, the 21-year-old shouted, calling on Chief Judge Damien Dumusois to warn him.
Stefanos Tsitsipas got what he asked for, and as it was the second offense during the match, it was deducted points.
The 21-year-old also struggled with cramp, and also said after the game that he had difficulty finding inspiration.
