Can Serena dominate scene again?

There may be no tougher act to follow in any sport in 2016 than Serena Williams' attempt to match her nearly perfect season of tennis last year.

Williams, who won the first three majors in 2015 and lost in the US Open semifinals - 26 consecutive wins in majors, just missing a calendar-year Grand Slam - will begin that attempt when she teams with Jack Sock for the American team at the Hopman Cup in Perth, Western Australia.

The Americans play their first match on Monday against Ukraine.
