Two Questions: Ball hits batter, Overthrow

[SC Ump]

#1 - I agree is still in the box.

#2 - I could not find a definition of "throw" in the rule book, but fortunately Webster defined it. In all cases (horse threw a rider, car threw a piston, sun threw a shadow, judge threw the book) the subject performed a specific action that caused an effect on the object. I think you will know when the fielder is throwing the ball.

Traditionally I have been taught the "lose possession" ruling is when the possession is lost during an attempted tag on a put out.
