two players

have hit 2 3Bs AND 2 HRs in the same game since 1956 (one HOFer and one ... not). ]]>

For example, if the average player hits home runs in some proportion *x* of at-bats, and they get 4 at-bats per game, then they should have two-HR games in something like 6*x*2 of their games. (They have probability *x*2 of hitting 2 HR in 2 AB chosen arbitrarily; there are six ways to choose the pair of at-bats.) So the square of the home run rate should look like the rate of 2-HR games.

This very crude analysis ignores the fact that some players hit more HR than others, though...
