Where these results come from. Each contest in the table was recorded from a named source, and for Grant Mayo that source is MuscleMemory. Open any contest above and that page names its own source and links to it where the source is still reachable. That archive no longer answers at the addresses we hold, so it is credited by name here and not offered as a link.

Only 2 head-to-head meetings on record so far, with Grant Mayo ahead 2 to 0 - too thin to call a rivalry yet.

Opponents are ranked by how often they shared a stage and how big the stage was, not by reputation. A meeting is one contest where both competed in the same division and both were placed.
