New Zealand No.1 Marina Erakovic has made it through to the quarter-finals of the Memphis International tennis tournament.
Erakovic, the fourth seed, beat unseeded Russian Evgeniya Rodina 6-3 6-4 in the second round of the WTA Tour event on Wednesday (NZ time).
She will face another unseeded opponent in the last eight - either former doubles partner Michaella Krajicek of the Netherlands or Belarusian Olga Govortsova.
Erakovic, 23, has risen to 54 in the latest world rankings, close to her career-best 49 achieved in mid-2008.
