MELBOURNE, Australia (AP) The Williams sisters have advanced to the third round at the Australian Open, with top-ranked Serena fending off set points before going on a 10-game roll to beat Vera Zvonareva 7-5, 6-0 and Venus beating fellow American Lauren Davis in straight sets.
Serena Williams, seeking a sixth Australian and 19th Grand Slam title, saved three set points in the ninth game before holding to swing the momentum of the match.
She said Zvonareva, a two-time Grand Slam finalist who played only five tournaments in 2014, started out aggressive ''and I was a little too passive.''
So she told herself: '''You know Serena, you've done so well here, you have nothing to lose.''
Zvonareva only won eight points in the second set.
