As far as base running is concerned coach is the STOP sign. The players should be thinking 120 ft (2 bases) on every play. I don't know how many times I have seen kids get to the base and heave a sigh of relief, start looking around then realize they should be on the next base...if they were watching the base coach.
If the runner is on 3B and they need to be told to go on a dink fly ball, tag up, infield ground ball I can understand, but the players need to learn to read the ball.
OH my gosh....this exactly happened to us two weeks ago. Runner on 1B Batter lays down bunt. Chaos ensues in the infield...and 3b is vacated with closest player more than 30 feet away. Runner on 1 gets to 2nd....stops....looks at me frantically waving her over. She makes it to 3B safe. Looks at me and says "What was I thinking, I should have been looking towards you but I should be thinking of getting to third when we lay down a bunt like that". YUP! Great self taught moment. She scored went back to the dug out and reminded all her teammates what they should be doing....I just smiled.
She knew what we wanted to do...had a brain fart...and recognized it. She knew she'd do better next time. I can't wait till next time!
