It will come as no surprise to anybody who has ever played the game but stepping into the batter's box and making contact with a baseball is hard.
Now imagine hitting the ball out of the yard twice in a single inning.
Sounds impossible, doesn't it?
Well, since June of 1880, the feat has been achieved on 64 occasions, with 61 different big leaguers having slugged soundly twice in a single frame.
From an array of pioneering bats to the trio to have achieved the feat more than once, here is the full list of every Major League Baseballer to have hit two home runs in a single big league inning.
