Does not touch first base

[jodibuck]

What is the proper procedure on appeal. Since the ball cleared the fence, we have a dead ball. How would the defense appeal the batter-runner missing first base? We had this occur in a Babe Ruth League tournament game, and the defense verbally appealed, just as a team would in a NFHS game. The umpires did not acknowledge the appeal. When the umpire put the ball back in play, the defense made a proper appeal, and the batter-runner was called out. What if the home run was a "walk off" homer. Would the defense have to request the umpire to give them a ball to make an appeal?
