Before this thread gets hijacked into the 1043rd rendition of the "what I think majors should be" discussion, something needs to be made clear. Every time this discussion comes up, the arguments tend to discount any major that doesn't involve MPO as not a "real" major, which is a faulty premise to start from. So let's be clear whether we're talking MPO only or majors across all ages and genders.
This year...
there are 3 MPO majors: Worlds, USDGC, European Open
there are 3 FPO majors: Worlds, USWDGC, European Open
there are 2 Pro age-protected majors: Worlds, Selinske
there are 3 Amateur (MA1/FA1) majors: Am Worlds, USADGC/USWDGC, Am World Doubles
there are 3 Amateur age-protected majors: Am Worlds, Selinske, Am World Doubles
there is 1 Junior major: Jr Worlds
Using ball golf as a comparison
Four majors for their equivalent of MPO: US Open, British Open, PGA Championship, The Masters
Five majors for their equivalent of FPO: US Women's Open, British Women's Open, LPGA Championship, ANA Inspiration, Evian Championship
Five majors for their age-protected tour (50+): US Senior Open, British Senior Open, Senior PGA Championship, Senior Players Championship, The Tradition
Also major championships for amateurs: US Amateur, US Amateur 4-ball, US Mid-Amateurs (with variations for Seniors, Juniors, and Women) Plus amateur versions of the British Open as well.
Do we really have "too many"?
