This is the reason why he is not seeded.
Coria is seeded 8, the current rankings are:
36 Coria, Guillermo (ARG ) 960
37 Rios, Marcelo (CHI ) 945
Marcelo will surpass Coria the next monday, but as you know the draw is made the previous week.
Yes Marcelo Ríos vs Guga Kuerten in first round, sucks! I would like to see that match but in QF's at least.
Anyeway good luck to Marcelo tomorrow
