Source-derived summary

In golf, winning all of the sport's major championships in the same calendar year constitutes the Grand Slam. The modern (professional) Grand Slam would mean winning the Masters Tournament, PGA Championship, U.S. Open, and Open Championship in the same year. Before the rise of professional tournament golf, the Grand Slam was achieved in 1930 when Bobby Jones won the four major championships of that era: The Amateur Championship, The Open Championship, the United States Open, and the United States Amateur.

Editorial analysis

Why this record matters

“Grand Slam (golf)” is worth following because a concise public description often conceals a longer documentary argument. Here, Grand, Slam and golf provides the most credible route into that argument.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 13, 2026. The first chronological checks are 1930.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
