World number one Rafael Nadal and Novak Djokovic have both booked their places in the second round of the ongoing Wimbledon Open following respective first round wins in straight sets.

Nadal defeated Dudi Sela of Israel 6-3 6-3 6-2 in his first match since winning last month’s French Open.

He will now face Mikhail Kukushkin of Kazakhstan in the next round.

Speaking afterwards, Nadal pointed out that there’s still room for improvement.

In his words, the Spaniard said: “After a while without playing on grass, it’s very important to start with a straight victory.”

“I went to the net a couple of times, later in the third set I served worse, but in general terms I served well.” The two-time Wimbledon Open champion added.

Former world number one Novak Djokovic is also through to the second round after he showed some of the form that took him to the top of the men’s game.

He saw off American Tennys Sandgren in straight sets 6-3 6-1 6-2 and will now take on Argentina’s Horacio Zeballos for a spot in the third round.

On his victory, Djokovic said: “I was a bit tense at the beginning.”

“It was quite a solid performance.” The Serbian 12-time Grand Slam champion added.

Fourth seed Alexander Zverev and fifth seed Juan Martin Del Potro also won their first round clashes.

Zverev defeated James Duckworth of Australia in straight sets 7-5 6-2 6-0, while Del Potro beat compatriot Peter Gojowczyk 6-3 6-4 6-3.

Other top ten seeds like Dominic Thiem and David Goffin were, however, eliminated in the first round following their respective losses.

Seventh seed Austrian Thiem succumbed to a back injury as he retired from his first round match with Marcos Baghdatis of Cyprus while he was trailing 4-6 5-7 0-2.

Australian Matthew Ebden stunned tenth seed David Goffin of Belgium in straight sets 6-4 6-3 6-4 to qualify for the next round at SW19.
