Doldrum Drills?

Hi Everyone-
This topic is not specific to pitching, but I thought I’d put it out there.
My team is roughly halfway in the season and is starting to flag a bit (they are 9U). Any ideas for fun drills that would break up
the monotony a bit?

Have an epic series if wiffleball games and let them have fun

Always found a game of knockout to be great. Pair them up and have them play catch. Any miss and the pair is out. Progressively move them further apart. I think my 9s would play this for two hours.

Four corners where the kids count how many in a row they can catch is also great. Better to have them too close - and more successful - than too far apart and have momentum fail.
