The United States Tennis Association have announced that there will be an extra day's rest for finalists at the 2013 US Open.
The decision is believed to have been made in response to some players complaining that they had to play the semi-final and final on consecutive days.
It now means that, for the first time, the final of the women's tournament will take place on Sunday, while the men's final will be pushed back to Monday.
"We listened to the players and understood we needed to accommodate their request for an extra day of rest between the semi-finals and final," said USTA spokesman Chris Widmaier.
"The USTA reached out to many of the top players, player agents as well as the respective tours. The day of rest is being embraced across the board.
"Because of the nature of the game, and to assure a final that can be played at the highest competitive level, you need an extra day of rest. We recognised that."
It has not been decided if the changes will stick for the 2014 tournament.
