🎾 Correct! Margaret Court holds the all-time record for most Grand Slam singles titles with 24. The Australian legend dominated in the 1960s and early 70s, winning her majors both before and during the Open Era. She also holds the all-time record for most Grand Slam titles overall, including doubles and mixed doubles, totaling an astounding 64. Court's career achievements are unmatched in sheer numbers. Though the majority of her singles titles came before tennis became fully professional in 1968, her dominance remains a towering record in the history of the sport. While Serena Williams came close with 23 singles titles, Court's record still stands. Whether it’s debated or defended, her position in tennis history as the Grand Slam queen is unshakable.
