Australian Open 2013: Sloane Stephens insists quarter final against 'hero' Serena Williams 'just another match' The court's the same size. You're still playing a regular person across the net. You've just got to go out and play. Despite Williams first playing Grand Slams tennis while Stephens was only five years old, the teen believes she will not be in awe, saying she got past that during their recent clash in Brisbane. "I mean, that was two weeks ago now, three weeks ago," she said. I played seven other matches or eight other matches, so I'm kind of past what happened then. But I think definitely just treat it as another match. You just go out and do your best. Against Jovanovski, Stephens steamrolled through the first set before the 56th-ranked Serb, 21, woke up and gave her a fright. The American grabbed the decisive first break on the Serb's opening service game and she didn't look back in a set that lasted just 25 minutes. Jovanovski, another of the tour's big grunters, put up more of a fight as the second set got underway. Both players held serve for 2-2 before Stephens hit a backhand long to give the Serb her first glimmer of hope with a break. But she threw it away immediately, netting a forehand at break point down before breaking straight back to go 4-3 in front as the intensity of the match rose. Stephens was rattled and making mistakes as Jovanovski capitalised, winning her serve and then breaking again to take it into a deciding set. Both players were struggling with their serve and the set saw five breaks as it turned into a baseline slugfest that Stephens finally won. First set I came out, I was playing good, not missing much. She was making a few errors," said Stephens. Then she brought it full force second, third set. I just had to find a way. I think mentally it was pretty tough.
