Madison Keys (born February 17, 1995) is an American professional tennis player. She achieved a career-high ranking of No. 7 in the world in October 2016 and has been consistently ranked inside the top 25 by the Women’s Tennis Association (WTA) since early 2015. Keys has played in one Grand Slam tournament final at the 2017 US Open, competed at the 2016 WTA Finals, and was a semifinalist at the 2016 Summer Olympics. She has won five WTA tournaments, all at the Premier level. Her biggest title came at the 2019 Cincinnati Open, a Premier 5 event. Known for having 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 the next generation of American tennis alongside Sloane Stephens, CoCo Vandeweghe, and Sofia Kenin. She debuted in the top 10 of the WTA rankings in 2016, becoming the first American woman to realize this milestone since Serena Williams seventeen years earlier. When Keys and Stephens faced off against each other in the 2017 US Open final, they snapped a streak of no American women aside from the Williams sisters appearing in a Grand Slam singles final since 2005. Keys has also had success on all surfaces, winning at least one title on each and having reached at least the quarterfinal stage of all four Grand Slam tournaments.
