Andy Murray and Rafael Nadal ease through in Beijing

Andy Murray promised there is more to come from him after booking his place in the second round of the China Open with a 6-2 7-5 victory over Andreas Seppi on Tuesday.

The top seed registered his eighth consecutive win against the Italian in Beijing, setting up a second-round clash with Andrey Kuznetsov - a 6-1 6-4 victor over fellow Russian Konstantin Kravchuk.

Murray struggled with a shoulder problem in August but believes he is returning to his best with every match.

"I thought I did okay considering I hadn't played much the past couple of weeks," he said.

"I think I can do better. But there was some good stuff in there. With each match, I’ll play better hopefully.

"No injuries. Felt fine. Just need matches now."

Last year's runner-up and second seed Rafael Nadal is also safely through following a routine 6-1 6-1 win against Paolo Lorenzi.

"Today I think I played a very solid match, playing very aggressive with my forehand," Nadal commented.

"I only played one not so good game. That was at 3-1 of the first set. But for the rest I played a very good match. I’m very happy."

It was not plain sailing for all seeds in Beijing, though, with Dominic Thiem beaten 4-6 6-1 6-3 by Alexander Zverev.

Milos Raonic triumphed 6-4 7-6 (7-1) and there were wins for Jack Sock and Fabio Fognini over Zhang Ze and Viktor Troicki respectively.
