(Added thanks) Wow, that is so bad! The funny thing is during all that he only lost one spot in the rankings, he started the run at 59 and now he is 60. Talk about really using those 10 points Indian Wells and Miami give for direct entrants.
He won't lose many points until the summer. He had a very good run in july and august last year, making semifinals in 5 consecutive tournaments (3 challengers and 2 atp).
