1) Star Drill: Put 1 player on 1st base, 1 at 2nd, one at home, and the rest at third. Hit a ground ball to the first person in the line at third, They throw the ball to 1st then run to 1st. 1st basemen throws it to 2nd then runs to second. Then 2nd throws it home then runs home, And so on.
2) ??????: Line up your players in two straight lines like this
O
5 4 3 2 1
9 8 7 6
then put a bucket next to five (O = bucket)
1 throws the ball to 6, then 6 to 2, 2 to 7, 7 to 3, 3 to 8,
8 to 4, 4 to 9, 9 to 5, then 5 puts it in the bucket. do this about 10 times. any balls that touch the ground during this they can't pick up. See how many balls you can get in the bucket!
Hope I helped
