As for 2013 the start of the year is going to be crucial for Rafa. He has an AO final to defend and that will likely be his first (or 2nd) tour level event back. If he loses early there it could cost him 1000+ ranking points and drop him out of top 4. Then he will have that much more pressure to defend a crap load of points from 2012.
