A spot in the next round is at stake on Wednesday, when Filip Cristian Jianu goes up against Zdenek Kolar in the Catania (Italy) round of 16. Zdenek Kolar has won 4 of the last 10. Filip Cristian Jianu has dropped 5 straight and sits at 3-7 over the last ten.

There's a wide gap in our ratings on clay, and our number follows from it. Jianu comes in off a compressed schedule. Little separates them; Kolar gets the nod on the finest of margins.
