Serena returns to tennis

The 23-time Grand Slam champion, who is warming up for the Australian Open, was at her dominant best after a slow start in which she saved four break points in the opening game of the contest at Margaret Court Arena.

Former world number one Williams has not played since withdrawing from last year's French Open second round in September with an Achilles injury, but made quick work of Gavrilova, striking 27 winners including 16 in the opening set.
