New Delhi: Australian Open 2018 saw a thrilling day with unexpected results. Starting with the Men’s singles then, Spanish tennis great Rafael Nadal opened his campaign with a 6-1, 6-1, 6-1 thrashing of Victor Estrella Burgos of the Dominican Republic.

The top-ranked and top-seeded Nadal wrapped up the win in 94 minutes to send a warning to the rest of the men’s singles field.

Nadal, who had won both the US Open and the French Open in 2017, dominated the match from the very first point and built up a 5-0 advantage in all three sets over his rival.

Burgos managed to hold his serve only once in the first set, which 2009 Australian Open champion Nadal sealed in 23 minutes. In the second set, Nadal lost his serve once in the sixth game after squandering two set points, but he recovered quickly to secure the set on Burgos’ serve.

Nadal continued to dominate the third set, again allowing his rival to hold serve only once.

This was Nadal’s first competitive match after his withdrawal from the 2017 ATP Finals in London due to a right knee injury.

In the second round, Nadal is scheduled to face Leonardo Mayer of Argentina, who defeated Chile’s Nicolas Jarry 6-2, 7-6 (7-1), 6-3.

Sixth-seed Marin Cilic of Croatia also advanced to the second round, defeating Canadian qualifier Vasek Pospisil 6-2, 6-2, 4-6, 7-6 (7-5).
