At a party celebrating Ball’s 100th birthday in 2010, Bill Erfurth, one of his former assistants at Oak Park, recalled a time when Ball signed up for a lesson at a local driving range without revealing his identity, according to an article in Golf Week. Ball pretended to struggle on his first few shots before making a point of paying attention to what the resident instructor was trying to teach him. By the end of the 30-minute lesson, Ball was striking the ball with his usual authority.
“This young pro was beside himself,” Erfurth recalled. “He thought he’d performed a miracle.”
