Aucklander Marina Erakovic's run of success in tournaments in North and Central America has elevated her rapidly in the International Tennis Federation's junior rankings.
In winning or finishing runner-up in five of her last eight tournaments, Erakovic, who a year ago was ranked 62nd in the world, is now - under the new ranking system - up to 13th in the singles and fourth in the doubles.
She is NZ's highest-ranked junior player (male or female).
