World number 1, Serena Williams, will launch her 2016 season at the Hopman Cup in Australia.
Serena reached the final of the mixed team event in 2014 with American compatriot, John Isnerto, kicking off a superb season where she won the Australian, French Open and Wimbledon, to take her Grand Slam singles haul to 21.
Williams has not played since her shocking semifinal defeat to Italian Roberto Vinci at the US Open in September which ended her bid for a rare calendar Grand Slam.
She pulled out of two events in China earlier in October, as well as the WTA finals in Singapore, citing the need to rest after a year spent carrying injuries.
Williams will be joined in the January 3-9 Hopman Cup field by Briton, Andy Murray and controversial Australian, Nick Kyrgios.
Australian teenager, Nick Kyrgios, created a big upset as he defeated Rafael Nadal 7-6 (7-5) 5-7 7-6 (7-5) 6-3 to reach the quarter-finals at Wimbledon.
Nadal had no answer for Kyrgios’ booming serve and thunderous ground strokes, the 19-year-old sending down 37 aces and hitting 70 winners during the course of the fourth round contest.
The world number one had lost the first set in each of his first three matches before recovering to win in four, but could not repeat the same feat against a rampant Kyrgios.
Kyrgios, who had being tipped for greatness by the likes of Andy Murray and Pat Cash in recent weeks, only claimed his first top-50 win a week before the victory over Nadal when he saved nine match points to beat Richard Gasquet in the second round.
The Australian teenager, who is world number 144, is the first man outside the top 100 to beat a world number one since 1992.
Serbia’s Novak Djokovic will face David Ferrer of Spain in Saturday’s (December 28) final of the World Tennis Championship in Abu Dhabi.
The Serbian defeated Jo-Wilfried Tsonga of France 7-6, 6-3 in the second semi-final on Friday.
Third-ranked Ferrer had earlier beaten world number one and Spanish compatriot, Rafael Nadal.
Tsonga used his power to good effect throughout Friday’s match, but world number two, Djokovic varied his shots and pace and never seemed to be working flat out.
The Serbian was watched by new head coach, Boris Becker, who seemed unsurprised by the result.
