Madison Keys

Madison Keys (born February 17, 1995) is an American professional tennis player. She has been ranked as high as world No. 5 in women's singles by the WTA. Keys has won ten career singles titles, including the 2025 Australian Open, defeating two-time champion Aryna Sabalenka. She was also the runner-up at the 2017 US Open.

Keys was inspired to start playing tennis after watching Venus Williams at Wimbledon on TV. Keys turned professional on her 14th birthday, becoming one of the youngest players to win a WTA Tour-level match a few months later. Keys first entered the top 100 of the WTA rankings in 2013 at the age of 17. She had her first breakthrough at a major in early 2015 when she reached the semifinals of the Australian Open as a teenager. Keys debuted in the top 10 of the WTA rankings in 2016, becoming the first American woman to realize this milestone since Serena Williams 17 years earlier. She reached the US Open final in 2017, losing to friend Sloane Stephens. Following years of injury struggles and lower results, Keys won her first major title at the 2025 Australian Open, consecutively defeating world No. 2 Iga Świątek and world No. 1 Aryna Sabalenka.

Known for a fast serve and one of the most powerful forehands in the game, Keys has used her aggressive playing style to become one of the leaders of her generation of American tennis, alongside Stephens. She has had success on all surfaces, winning at least one title on each and having reached at least the quarterfinals of all four majors.
