Last night and this morning on the ATP website above the rankings display there was this note :
Rankings Note: The South African Airways ATP Rankings as of Monday, 19 November are the official year-end rankings.
that means the rankings after the DC final and before Tyumen and Toyota challengers.
I'm not exactly sure what it means and/or implies.
I wonder if it implies that the "Race for London 2013" will include the challengers of Tyumen, Toyota and the Challenger Tour Finals.
