The wins keep coming for Pilot Pen commit Flavia Pennetta, who upset Venus Williams to reach the quarterfinals of this week's event in Cincinnati. Pennetta's 13th straight match win coupled with early losses by Nadia Petrova and Ana Ivanovic has Pennetta about to jump into the top 10 for the first time.

Pennetta, who won at Palermo (Italy) and Los Angeles in her last two events, would be tied with Ivanovic for the 10th spot if she did not advance any further. It appears as if Ivanovic would hold the tiebreaker, denying Pennetta of top 10 status. But if she beats Daniela Hantuchova in the quarterfinals, she would definitely crack the top 10.

If that happens, she will join No. 8 Caroline Wozniacki to give the tournament two top 10 players. Wozniacki would jump up a spot if she reaches the finals in Cincinnati.
