The top 10 neighbors for The Masters form a tightly compressed, single-sport cluster — no standout outlier, no cross-kind surprise, just a dense band of golf-specific entities spanning athletes, a sports league, and one TV channel.
Similarity here measures how closely two entities' audiences resemble each other in composition. The shape is flat: scores run from 0.98 down to 0.96 across the top 10, a range narrow enough that no single neighbor dominates. Justin Thomas leads at 0.98, followed by PGA Tour at 0.98 and Jordan Spieth at 0.98. Phil Mickelson (0.97), Jason Dufner (0.97), Dustin Johnson (0.97), and Rory McIlroy (0.96) follow in a tight pack. Eight of the top 10 neighbors carry the Athletes subcategory; the ninth is PGA Tour, a Sports League; the tenth is Golf Channel, a TV Channel at 0.96. The only other Sporting Event in the top 10 does not appear — the two fellow Sporting Events in the broader results (U.S. Open and The Open) sit just outside the top 10 at positions 20 and 21 in the full set.
The cluster is essentially a complete map of professional golf's participant and broadcast ecosystem, with no athletes from other sports, no general sports media, and no non-golf brands appearing in the top 10.
This audience shape reflects a sport-specific following with very little crossover pull from outside the game itself.
