At the T-Ball and Coach Pitch levels, it may be challenging for players to throw and catch to each other, so just rolling the balls back and forth to each other is an easier option!
Players may have a difficult time knowing where to position themselves if you tell them to go to "shortstop" or "first base", but if you use the color cones that OLL provides, it will make is easier!
Use an easy format of making lineups by the player's uniform numbers. Start at different numbers each inning, or even go backwards! Make sure, throughout the season, each player has started the batting order and was the last in the order.
