today, all the slams have a 128-players draw, but it's not always been like this... i think (correct me if i'm wrong) that the last non 128-players draw for a slam was the 1987 australian open: http://www.atpworldtour.com/Share/Event-Draws.aspx?Year=1987&EventId=580&Draw=ms it was a 96-players draw. it seems that all the 16 seeds (there are 32 seeds in the slams only since wimbledon 2001) received a bye, and that 16 other byes were randomly distributed in the draw. but sometimes, there have also been more than 128 players, such as the 1972 US open. it doesn't appear on the ATP online database: http://www.atpworldtour.com/Share/Event-Draws.aspx?Year=1972&EventId=560&Draw=ms but it does on the ITF online database: http://itftennis.com/procircuit/tournaments/women's-tournament/info.aspx?tournamentid=1010004556 (with an interesting emerson-borg in this 'extra' 1st round) so... a 256 draw with 108 byes = 148 players. - strangely, it seems some seeds (e.g. cliff drysdale ) had to play an extra round while some unseeded players didn't... does anybody have more info about how they made the draw ? - is this the largest draw ever for a pro-tournament ? (the other extreme being the pepsi grand slam quartet ?) - does anyone have something like a table with the number of players in the draw for the slams of the open era (or further back in time if you can !) ?
