Petrova defeats Mauresmo in Qatar Final

Another upset of sorts - Nadia Petrova of Russia has defeated the on-a-roll Amelie Mauresmo of France.

Amelie Mauresmo failed to regain the world number one spot when Nadia Petrova beat her 6-3 7-5 in the Qatar Open final on Saturday.

This is only Petrova's second career title - it remains to be seen if she is going to get better at defeating the big-name players to push her rank up.
