One of the things I stress in my softball practice is throwing accuracy.   Two of my favorite drills to work on this are   the Relay Drill and the Tag Out Drill.

Relay Drill
Line up from one of the lines with three girls stretched out across the diamond about 50 -75 feet apart.

Make throws like a relay from outfield.
Have three or four groups go at once, to make it a race.
Make sure girls make good throws and pivot the proper way to make next throw.

This drill speeds up cut offs and turning the proper way as well as the speed it is done, while making it fun for the girls.

To throw a twist onto the drill make the last place team do 5 pushups, to push them a little harder.

Tag Out Drill
This is a drill targetted to get the players to throw the ball to the proper location for a tag out – NOT a force out.

Set up a 55 gallon trash can (laid down horizontally with the mouth open to the players) at 3rd base and home.

Infielders will throw the ball from their position into the mouth of the can.

This is practiced with infield and outfielders. (Outfielders may hit the cutoff man and then she turns and throws into the can).

This gets the throwers throwing the ball in the correct vicinity for the player to quickly apply the tag.
