re: Most forgotten amazing sports feats?

Also only one player has hit a walk-off, inside-the-park, grand slam--the late Roberto Clemente (who also had exactly 3,000 hits in his career, the last on his final at bat).

And Clemente is the only MLB player for whom the five-year waiting period was waived. (When Gehrig was elected, there was no mandatory waiting period. However, he was nominated in a special election as the Baseball Writers Association was uncertain as to how long he would live, so at their 1939 winter meeting they held a special election on which he was the only nominee.)
