7. Gene Sarazen vs. Walter Hagen
When Sarazen met Hagen in a challenge match in October 1922, the contempt was palpable. Hagen, the reigning British Open champ, had skipped the PGA (ducking Sarazen, some said), which Sarazen won. Sarazen, then only 20, had also won the '22 U.S. Open. This was for No. 1 — and much more. As Sarazen put it: "I didn't like the way he kept calling me 'kid.' I was a champion and I wanted Hagen to respect me as a champion." The kid won 3 and 2.
