Here’s an often not required rule of the game of cricket… if the ball is thrown back towards the stumps, as is usual, but the throw is bad and the ball goes wide, the batsmen are entitled to run again if they can cover the distance before the ball is back in control again, and any bonus runs add on to the score. If the ball is thrown so hard it reaches the fence, then those runs become four as though they’d been hit by the batsman. Any runs like these are called ‘over throws’ for clear reasons.
If the fielder manages somehow (usually by mistake in a humourous and embarrassing misthrow) to toss the ball over the fence on the full, then they become six over throws, just as though the batsmen had hit the ball for six over the fence in the first place.
And now you know.
