- An extra $4 million will be on offer for the 2013 U.S. Open tennis tournament
- Organizers have also agreed to schedule a day of rest between finals and semis
- Defending champions Andy Murray and Serena Williams welcome the changes
- There will be a record $29.5 million in prize money -- a 34% increase since 2011
Record prize money and an extra rest day for finalists -- U.S. Open tennis chiefs have taken note of player complaints and made significant changes for 2013.
The tournament's women's final will now be held on a Sunday and the men's title match on a Monday, while the total prize purse will increase by $4 million.
"I'm pleased that the USTA has modified the U.S. Open schedule to include a day of rest between the semifinals and final," defending men's champion Andy Murray said on the New York grand slam's website.
"Together with the prize money increase, it's good that they've taken on board the players' concerns."
Women's champion Serena Williams was also happy with the changes, which mean the female players will play their last-four matches in Friday's afternoon session.
"Both the prize money increase and the addition of a day of rest are great for the players," the American said. "These moves make the tournament stronger than it's ever been for all players."
