Helmets
Use any time players are swinging bats, are around others with bats or running bases.
Supervision
Watch your players carefully at all times.
Bats and Balls
No player should pick up a bat or ball unless a supervising adult has said it is OK. Players should never throw to another player unless that player is looking.
Be Cautious
If you don't think your players are ready for a particular drill, just choose another. You can also vary drills to ensure safety by rolling grounders instead of hitting fly balls, using soft-core or tennis balls instead of baseballs.
Spacing
Any time more than one player is swinging a bat or throwing a ball, make sure there is plenty of distance between everyone. Structure practice so that there will never be players from one drill running through another to chase loose balls, etc. Players not actively participating should be stationed in protected areas.
First Aid
Always carry a first-aid kit and instant ice packs. Keep parent and emergency phone numbers handy in case of more serious injuries.
