tennis: Top-ranked Novak Djokovic produced another scintillating performance to beat Swiss Stan Wawrinka at the ATP World Tour Finals in London last night.

The 29-year-old Czech crashed 6-1 6-1 to Wawrinka on Monday but he rebounded to win his second group match yesterday, outclassing Marin Cilic 6-3 6-1.

"I think that's the beauty of this event," he said after keeping alive his hopes of claiming a semi-final spot with a top-two finish in Group A.
"One day you can be swept out from the court like I was and in two days' time you can come up and play different tennis."
