Ivan is not bad on clay as many people think. he can atleast return serve on clay and stay in rallies, if he can cut down on UE's he can win some matches and his ranking wont go down much, rest of the season there is NOTHING to defend.
I don't think he is especially bad on clay, but he isn't playing his best tennis anymore. It's possible he won't be seeded in RG, and I don't see him making 3rd round that way. Even if he's seeded, I don't think it'll happen. Hope I'm wrong.
