What is the distance from home plate to second base on the softball field? A softball field has base lengths of 60 feet. What is the distance from home plate to second base on the softball field?

17. HOMERUN  There are runners on first, second and third with no outs. The ball is hit to the short stop positioned on the baseline halfway between second base and third base. To prevent a run from scoring the play is at home plate. Assuming the ball is hit directly to the short stop, how far must he throw the ball to get the player out at home?
