(CNN) -- 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."
