Olderer hasnt been a factor in iw/miami since 2006, there is no theseway he is winning either of
these titles. His best chance is cinci/paris indoors/basel etc
I would also give him an excellent chance in Madrid especially if it is true that Rafael Nadal is not going to play there.
It's the new blue clay. He won there in 2009, and lost to Nadal in 2010 and 2011.
Also Halle has to be included as well. He's won 5
out of the last 6 times he's played there.
And I wouldn't dismiss him from the Olympics, or Wimbledon, or the US Open, but it would be clearly more difficult, as any slam is for anybody (except maybe Nadal at Roland Garros).
