For their stellar play at the 2011 US Open, and during the summer's Olympus US Open Series, Novak Djokovic and Serena Williams each added $500,000 to their Flushing prize money totals.

Djokovic, the 24-year-old Serbian champion, collected a $2.3 million check from the purser's office in Arthur Ashe Stadium, $1.8 million of which came from winning the US Open. The added supplement came from finishing second in the 2011 Olympus US Open Series Bonus Challenge Standings with 170 points from playing in Montreal's Rogers Cup and Cincinnati's Western & Southern Open, winning the former and reaching the finals of the latter.

He finished second to the United States' Mardy Fish, who had 230 standings points.

Williams, meanwhile, lost the women's final in Flushing to Australia's Samantha Stosur but still managed to bring home $1.4 million - $900,000 for the Open, $500,000 for winning her first career OUSOS title. The 29-year-old amassed 170 Bonus Challenge points by winning the Bank of the West Classic in Stanford and the Rogers Cup in Toronto, Ontario.

Had Williams beaten Stosur, she would have received a $2.8 million payout, which would have been the largest in tennis history. The women's sports purse record is still held by Belgium's Kim Clijsters, who netted $2.2 million in 2005 for winning both the US Open and 2005 OUSOS points titles.
