I think he is co favorite for the Wimbledon title with Rafael Nadal and co favorite for the U.S Open title with Djokovic (and possibly Nadal as well but too early in his case). At the French a semifinal would be a great result. Outside shot to get to #1 this year but probably wont. Even if someone won 2 majors and Djokovic ended up with only 1 I think he would still be at #1 as he is so consistent. Nadal might not overtake Djokovic for #1 even if he won the remaining 3 majors given the points he already has given up with absences.
