At the moment it is the only major tournament where the players don’t have a day off between the semifinal and the final matches. They are played on two consecutive days, Saturday and Sunday.
The weather has also made life hard for the organisers for the last four years with the final having been postponed till Monday.
16 time Grand Slam champion Federer welcomed the proposal of a 15th day to the tournament. The women’s final would also be pushed back from Saturday to Sunday afternoon.
The other alternative that the USTA is considering is to move the men’s semifinal matches to Friday and keep the final in the Sunday afternoon.
The US Open “Super Saturday” is very popular amongst the spectators, as the two men’s semifinals and the women’s final match are played on the same day. Australian Open, Roland Garros and Wimledon all have the same schedule that is different to the US Open. The women’s semifinals on Thursday, the final on Saturday and the men’s semis on Friday and the men’s final on Sunday.
