For the poll, Del Potro. Nobody thought he would crack the fedal wall
If you check out MTF at the time, there was a mayor sensation that Delpo could do it, because he has proven beforehand that he could and was growing and getting gradually better and better throughout the year. It wasn't a fluke, Delpo showed he was progressing in solid steps that year. So we all felt Delpo had a chance at the Fedal wall, specially against Nadal.
