We can notice the diverse changes to the Top 10 that are momentarily in the live rankings.
Murray is on the second position once again, and it's very hard to see him not there at the end of the week. If he wins the next match, it's a guarantee, no matter what Federer does.
Del Po is in front of Berdych without even playing in Madrid. But Berdych can defend this position easily by getting into the QF.
Tipsarevic is in danger of falling out of the Top 10. All is needed is either Almagro getting the QF spot, or Haas the SF, Nishikori or Wawrinka the Final, or Simon or Monaco winning, but the last 4 of these is less likely to happen.
