According to USA Today, Fred has been using a yellow golf ball at the 2023 Masters purely for the sake of visibility.
The 1992 Masters champion can see a yellow ball better than a white golf ball. Is Fred the only golfer who uses a yellow golf ball? Not exactly!
According to a report from Golf, the popularity of yellow golf balls has slowly been on the rise over the past few years, even though certain pro golfers like Tiger Woods always thought, "they were for hacks," (per an interview Tiger did on the Another Golf podcast).
Tiger also roasted Fred for using a yellow golf ball on the podcast. Tiger said, "We give [Fred] grief all the time about using the yellow ball. But he absolutely loves it because he can’t see anymore. You should see the front on his phone; it’s like one letter per screen."
