Whilst most of us will be passed out under thick duvets, Novak Djokovic will be resuming the defence of his China Open trophy at 5.35am Friday morning.
Djokovic plays Giles Simon and is a strong 2/9 favourite but the Frenchman won the Open de Moselle at the end of September and is high in confidence.
Simon has beaten Djokovic just once in the five times they’ve met and is 3/1 to win on Friday.
Nikolay Davydenko faces John Isner straight after the completion of that match and is 8/15 to beat the powerful American.
Since losing to Mardy Fish in the final of the Atlanta Tennis Championships in July, Isner has struggled to find his form on the hard courts and is short at 11/8 to beat Davydenko.
But the Russian has also been struggling on the hard courts, exiting the US Open in the second round to Richard Gasquet before losing to Igor Andreev, also in the second round of the Malaysian Open.
Davydenko is 8/15 to win but 3/1 to win in three sets.
Andy Murray is a huge 1/7 favourite to beat Ivan Lubijic despite his 3-2 head-to-head record over the Croatian.
Lubijic is yet to get past the second round since the clay court season finished in July and is 4/1 to beat Murray.
The last three times the two have met, they have all finished in straight sets and Murray is 4/9 to win in straight sets whilst Lubijic is 8/1 to win in straight sets.
Robin Soderling faces David Ferrer and the Spaniard has only ever beaten Soderling on clay.
Ferrer is 11/8 to beat Soderling but the Swiss is the strong favourite at 8/15.
Soderling has never beaten Ferrer comfortably and the value is in Soderling to beat Ferrer 2-1, which is available at 3/1.
Djokovic is the 2/1 favourite to win the China Open. See the full China Open betting odds market here.
