1 Perth's Hopman Cup provided Daria Gavrilova with a special keepsake (though she was actually partnered with fellow Aussie Nick Kyrgios).2 Also in Perth, Belinda Bencic, Kristina Mladenovic and Alexander Zverev rang in the New Year together.3 CoCo Vandeweghe had her teammate Jack Sock close by for the New Years Eve celebrations.4 Top seeds Andy Murray and Novak Djokovic went casual in Doha, while the rest of the field freshened up in business attire.5 Serena Williams wore the best of both worlds (or seasons) by pairing cutoff shorts with a long coat.6 It's only appropriate to end (or start dry January) with Nicole Gibbs holding a massive bottle of champagne.
