Anderson has a good draw, he should make the SFs here, and I also think he'll make the final.
Sela has an OK draw but not an "easy" one. Zemlja and Ignatik are good players who can beat him.
Sela has a good momentum in his career because his last loss to someone from behind the top 15 was in LA (July) but he had a bad draws :Youzhny second round at the US and Melzer twice (davis and bangkok)
the last challenger he participated is vancouver (where he won the title 3 times)
