Abbreviation 'GP' for tournament type
I was looking at the ATP website and was looking at some old match results from the 90's for certain big name players of today. I saw some abbreviations in match results for the type of tournament being played in such as:
FU = Futures
CH = Challenger
GP = ?
Anyone know what "GP" stands for? The only thing I could find with Google's help was the old "Grand Prix" tour, but that name died in 1989 from what I read - that's when it became the ATP Tour. Anyone know what 'GP' stands for?
