Dudi Sela dropped out of the world's top-100 for the first in over a year on Monday, falling to number 109 in the ATP rankings. The 23-year-old broke into the world's top-100 last October and was ranked as high as 57th seven months ago. However, early exits in the Challenger tournaments in Seoul, Dnepropetrovsk and Helsinki in the last three weeks, resulted in an 18 place drop in Monday's rankings. Sela, who played his last match of the year in Helsinki last week, now faces the prospect of not playing in next year's Australian Open qualifiers, as only the world's top 104 players enter the main draw automatically. In the women's rankings, Shahar Pe'er, once regularly ranked in the top-20 remained at No. 38 in the world. The young star was named Jerusalem Post Israeli Sports Personality of the year in 2007 by readers.
