Serena Williams Set For 2016 Tennis Season

Top-ranked Serena Williams will combine with Jack Sock once again when she opens her 2016 tennis season at the Hopman Cup tournament in January.

Williams, who won the event in 2003 with James Blake and in 2008 with Mardy Fish, has been troubled by injury late this year, but expects to be ready for her now standard Australian Open preparation event.

World No. 2 Andy Murray will also head to Perth for the Jan. 3-9 event, partnering with Heather Watson for Britain.

Troubled Australian Nick Kyrgios will play in one of the host nation's two entries -- Australia Green -- while former No. 1 Lleyton Hewitt joins Casey Dellacqua in Australia Gold.

After opening the 2015 season at the Hopman Cup, Williams went on to win the Australian Open, French Open and Wimbledon, as well as reaching the U.S. Open semifinals.
