He's hardly played this year, and clay isn't his best surface, but he's done really well this week - wins over Callieri, the in-form Chela, the dogged Davydenko and then the talented Almagro. That is an impressive list of victories - Nadal will be a different kettle of fish, but I reckon Hewitt can still push him hard, although maybe not as hard as Davydenko pushed Nadal.
