Seles, 50, an International Tennis Hall of Famer who retired with nine Grand Slam singles tournament wins and 59 career titles, inspired Wimbledon's Centre Court "grunt-o-meter."

“Some people loved it (the grunt), others hated it,” Seles told the Wall Street Journal in 2013 via the International Tennis Hall of Fame's website. “I grunted since I was age 7. I was a little girl, and they didn’t have kid’s racquets in those days. So my dad just gave me his racquet to play with, but I was tiny, so I put all my energy into it, just the same way I played with two hands from both sides, because I had to. It wasn’t an issue until I became No. 1 and then the competitors always try to find a little edge started to complain, because at the end of the day it [tennis] was a super competitive industry.”

Williams, 42, widely regarded as the greatest female tennis player of all-time, retired in 2022 with 23 career Grand Slam singles titles, the most of the Open Era and ranked as the world No. 1 singles player by the Women's Tennis Association for 319 weeks, including a joint-record 186 weeks.
