Collin Morikawa won the 2021 British Open at Royal St. George’s Golf Club using a blended set of irons that consisted of TaylorMade P•770 (4), P•7MC (5-9) and P•730 (PW) irons. During the seasons that followed, he kept using blended sets that often included some prototype P•7CM irons (with the CM standing for Collin Morikawa).
