re: Most forgotten amazing sports feats?

Another unusual feat involves players hitting for the cycle.

Only two players have hit for the cycle both as a member of a team and as an opponent of the team when it took place--Joe Cronin (as a member of the original Washington Senators against the Boston Red Sox, and later as a member of the Boston Red Sox) and Adrian Beltre (as a member of the Seattle Mariners against the Texas Rangers, and later as a member of the Texas Rangers). Beltre is the only one to accomplish both events in the same ballpark (Rangers Ballpark in Arlington).

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.)
