Curiosity question as there was an argument at my kids 10U baseball game. 2 Outs. Batter swings and misses a 2nd strike pitch. Catcher misses the ball and 3rd base coach yells for batter to run to first. Batter takes off and Catcher throws to first and the batter is tagged before reaching first and a runner at 3rd runs home. The umps send the batter who ran to first back to the batters box and the other team argues the runner who came from 3rd should be safe as he stole home. Ump said no go and kid who went home had to go back to 3rd. I thought that was the right thing to do as the kids are just 10 but what should be the call be by the rules?
