The 2009 Australian Open was a tennis tournament played on outdoor hard courts. It was the 97th edition of the Australian Open, and the first Grand Slam event of the year. It took place at the Melbourne Park in Melbourne, Australia, from January 19 through February 1, 2009. Second seeded Serena Williams regained the women's singles title and recorded her fourth Australian Open title and tenth Grand Slam title overall after defeating third seed Dinara Safina (6 0, 6 3). Serena, partnering her sister Venus, also won the women's doubles tournament. Rafael Nadal defeated Roger Federer (7 5, 3 6, 7 6 (3), 3 6, 6 2) to win the men's singles title. This is Nadal's first hard court grand slam, having previously only won on clay at Roland Garros (four times) and grass at Wimbledon (once). He also became the first Spaniard to ever win the Australian Open. This tournament featured 20 five-set men's singles matches, the most since 1988. In men's doubles, another sibling pair took the title as Bob and Mike Bryan defeated Mahesh Bhupathi and Mark Knowles.
