Back this week to his CH doubles ranking, up one spot to #6. He surpassed his doubles partner, Melo (for the first ever?).
Ivan is just 40 points short of #5. He's not defending any points at the AO whereas #5 is defending 360, so he might be able to do it.
Melo is in the finals this week and Ivan is not playing so Melo will probably surpass him again.
