Eastbourne: Novak Djokovic passes first grass test with straight-sets win over Vasek Pospisil

Top seed Novak Djokovic passed his first grass court test of the season today, defeating Canadian qualifier Vasek Pospisil 6-4, 6-3 to reach the quarter-finals at Eastbourne. The Serb is playing a pre-Wimbledon event for the first time since 2010 and will next face American Donald Young.

The three-time Wimbledon champion got onto court after rain washed out Tuesday's play -- save one game in the Djokovic match -- leaving organisers with a backlog to get through. The former world number one claimed his fifth victory in as many attempts against Pospisil, who is now 4-22 lifetime against top 10 opponents.

"That was the first official grass court match for me this year," Djokovic said. "I'm glad that I came here to Eastbourne. I have had a great couple of days of training with good players, different styles of game. Yesterday it obviously wasn't really enjoyable to see the rain falling all day.

"But today we almost played a full match, so I'm glad for that. I felt good on the court, considering it's the first match. I played against an opponent that has a really good game for grass. Serves well, comes to the net, has a good variety. It was a really, really solid win. I'm happy with it."

Djokovic, who will be advised by Andre Agassi at Wimbledon, is the second-highest-ranked men's player to ever compete at the Aegon International behind then-number two Marcelo Rios in 1998.

In the men's first round, Russian Daniil Medvedev knocked out fifth seed Sam Querrey, beating the American 6-3, 7-5. German Mischa Zverev, seeed sixth, beat Ryan Harrison of the US 6-4, 7-6 (11/9).

On the women's side, top-ranked Angelique Kerber recovered to beat Czech Kristyna Pliskova 4-6, 6-1, 7-5, as the German returned to action for the first time since her opening round defeat at the French Open.

Kerber is fighting to hold onto her number one ranking and withdrew from last week's Birmingham event with a hamstring strain. She trained in Mallorca after recovering from her injury but has yet to capture a title this year or beaten an opponent inside the top 20.

Roland Garros finalist Simona Halep, who trails Kerber by just 115 ranking points, rallied to defeat China's Duan Ying- Ying 3-6, 6-3, 6-2, while Bulgarian Tsvetana Pironkova -- a 2010 Wimbledon semi-finalist -- thumped Monica Niculescu of Romania 6-0, 6-4.

Two-time Grand Slam winner and seventh seed Svetlana Kuznetsova overcame German Mona Barthel 4-6, 7-5, 6-2 while France's Kristina Mladenovic, seeded ninth, dusted aside China's Zhang Shuai 6-0, 6-4.
