Some think this match could be a blowout, but I tend to think it could last for a while. Nadal isn't all that sharp and Soderling has beaten him here before.
I'm not saying that will happen again, but Soderling wil make him work.
Nadal has a 5-2 edge ove Sod and all but one match have been competitive. I'm not sure what happened when Nadal beat Robin 6-1, 6-0 in Rome back in 2009.
Look for a close one, Nadal pulls it out, though.
