Top seed Rafael Nadal of Spain displayed a dominating show at Shanghai Masters by wrapping up a second-round match against Swiss Stanislas Wawrinka 6-4, 6-4 on Wednesday.

Winning three Grand Slams and three ATP 1000 Masters, the 2010 version of Nadal was simply unbeatable.

Apparently, Wawrinka was not the right person to threaten the 24-year-old Spaniard's throne, for he had lost all of their previous six meetings.

Nadal, who dropped only eight matches this season, raised his winning record to 67 (out of a total 75 matches) after gaining Wednesday's triumph.

As the server of the first game of today's match, the Swiss made too many unforced errors to hold his serve. Nadal flashed an early break to establish a 2-0 lead. Neither player was able to break again in the rest part of the first set, which the left-handed world number one finished 6-4.

In the second set, Wawrinka struggled to resist another early break from Nadal, but he failed his attempt in the seventh game to allow his opponent a 4-3 lead. Nadal maintained his top form afterwards, and closed out the match 6-4.

Wawrinka produced 36 unforced errors throughout the match, while Nadal only made 12.

Nadal experienced a brief press conference, with merely three questions to answer.

"Wawrinka is a very good player and is very difficult to have a victory today in straight set," said Nadal, who had never lost a set to his Swiss opponent. "But it wasn't one of these very very difficult days."

"For sure for moments you are more tired than in other ones to do the rest of the things outside the court, but you have to do it," said currently strongest male tennis player in the world, when asked about his secret of saving his energy.

"Better to do it with the right way than the wrong way."
