When a runner reaches their base safely, the base coach will often congratulate them on reaching the base, then discuss strategies for base running to fit the current situation and/or their skill set.
Base Coach Rules
The coaches' boxes are positioned at first base and third base and are used for the team on offense. Acting as an extra set of eyes, coaches stand in the coaches' boxes to direct their players when to stay on base and when to run to the next base. The next batter's box or the on-deck circle in baseball terminology is for the batter to stand in and warm-up his swing waiting for his time at bat.
