There was a new release stating Rafa had agreed to play Stuttgart. Beyond that plug in the manditory events. It is doubtful he would elect to play any other non-required events because he could not count the points.
come on his 5th best is 20 points, supposing he wins stuttgart its 55 for QF of artois. if he wants to be no1 at the end of this year he should get as many points for the 5bests as possible, winning something like bastad would be nice. 175-55=120 which still may be of use.
i know it would be a bit tiring etc, but if rafa plays his best on the hardcourt, it may be the matter of each and every point at the end of the season to maintain the no1 in the race
