Marina Erakovic is making fast tracks since making her professional tennis debut in Auckland in January.
The 17-year-old Aucklander was beaten in the semifinals of a US$50,000 ($70,700) tournament in Fukuoka, Japan, but is now up to No 283 in the world. Seven weeks ago her ranking was 613.
The top nine players are unchanged in the rankings this week, with American Lindsay Davenport heading the list.
