Serena Williams

Serena Williams is widely regarded as the greatest female tennis player of the Open Era and a strong contender for the greatest of all time. Her 23 Grand Slam singles titles are the most in the Open Era, and she completed a non-calendar year 'Serena Slam' twice (2002-03 and 2014-15). Williams revolutionized the women's game with a combination of unprecedented power, athleticism, and a devastating serve that redefined offensive tennis. Her career spanned over two decades, during which she dominated across all surfaces, winning each major at least three times. Beyond singles, she also won 14 Grand Slam doubles titles with her sister Venus and two in mixed doubles. Her impact transcends statistics, as she became a global icon who inspired generations and fought for equality, competing and winning majors into her late 30s and as a mother.
