As Coco Gauff took on Mayar Sherif at the French Open, a bizarre fact about her surfaced. The American star had taken the first set 6-0. Gauff's unusual courtside routine involving her racquets left many fans puzzled, but former Wimbledon finalist Sabine Lisicki explained the science behind it.
Higher temperatures can loosen racquet strings faster, slightly impacting control and feel during rallies. By cooling the racquets between games, players can maintain more stable string tension and more predictable ball response in hot conditions.
Coco Gauff and her boyfriend Jalen Sera's combined net worth is estimated to be around $36 million. Most of that fortune comes directly from Gauff's tennis career, endorsement empire, and growing business ventures.
Gauff has already earned more than $24.3 million in career prize money through WTA Tour events and Grand Slam tournaments, but endorsements continue to drive the largest portion of her income.
