Madison Keys

Madison Marie Keys (born February 17, 1995) is an American professional tennis player. She has been ranked as high as world No. 5 by the WTA. Keys has won ten career singles titles, including a Major at the 2025 Australian Open. She was also a finalist 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 achieve this milestone since Serena Williams in 1999. She reached the US Open final in 2017, losing to Sloane Stephens. Following years of injury struggles and lower results, Keys won her first major title at the 2025 Australian Open, defeating world No. 2 Iga Świątek and world No. 1 Aryna Sabalenka in the semifinal and final, respectively.
