Madison Keys

American with one of the biggest games on tour who won her first Grand Slam singles title at the 2025 Australian Open.

Madison Marie Keys was born on 17 February 1995 in Rock Island, Illinois, to attorneys Rick and Christine Keys, and became interested in tennis at four after watching Venus Williams play at Wimbledon on television, telling her parents she wanted a white tennis dress just like Williams's. They agreed on the condition she took up the sport herself, and she began at the Quad-City Tennis Club before moving to Florida with her mother and sisters at ten to train at the Evert Tennis Academy. Keys turned professional on her 14th birthday in 2009, and developed into one of the most powerful servers and ball-strikers in the WTA, reaching a career-high singles ranking of world No. 5. She reached the final of the 2017 US Open, losing to fellow American Sloane Stephens. Keys won the 2025 Australian Open, defeating world No. 1 Aryna Sabalenka in the final for her first Grand Slam singles title at 29 years old, after 46 previous major appearances — one of the longest waits for a maiden title among the sport's elite players. She is married to fellow professional player and coach Bjorn Fratangelo, who coaches her. Keys founded the Kindness Wins Foundation, promoting anti-bullying initiatives, and continues to compete at the top level of the WTA Tour, remaining one of the most powerful hitters in the women's game.

Keys is known for her aggressive baseline game built around powerful groundstrokes, particularly her forehand which can reach speeds over 70 mph. She possesses one of the most potent serves on the women's tour and prefers to dictate points from the baseline with her attacking style.

Keys has been a consistent top performer for American women's tennis during her career, helping maintain the United States' presence in the upper echelons of the sport.
