Sloane Stephens through to 4th round at Australian Open

Sloane Stephens is having another good Australian Open, advancing to the fourth round with a 7-5, 6-4 win over Elina Svitolina of Ukraine on Saturday.

Last year, Stephens made it to the fourth round or better at all four majors - joining Serena Williams and Agnieszka Radwanska as the only players to achieve that feat.

And Stephens, seeded 13th this year, beat Williams in last year's quarterfinals at Melbourne Park, one of only four losses for Williams in 2013.

The 20-year-old Stephens, who has never lost to an opponent ranked lower than her in a Grand Slam event, will play either two-time defending champion Victoria Azarenka or Yvonne Meusburger in the next round.
