Travel ball — often two or three games in a day. The goal is to keep him sharp and reset from game one through the last, and to keep one bad at-bat from following him into the field.
The night before & morning of
Bag checked — glove, cleats, batting gloves, helmet, water, and real snacks for between games, more than you think. A real breakfast, hydration starting there. Get to the field early enough for a real warmup — the routine footwork is sharper when he's not rushing off the bus.
Warm-up (before the first game)
Throwing to get the arm loose, then ground balls — routine speed, feet through the ball, not the flashy ones. A few swings off a tee or front toss the other way so the first at-bat's approach is already grooved. One focus going in: on the routine play, slow feet.
Water and off his feet first. A real snack, nothing heavy. Don't rehash the last game — if he went 0-for or booted one, one sentence and move on. By the second and third game the tired legs show up as rushed feet in the field and a big pull-happy hack at the plate, so the between-games reminder is simple: two-strike approach, slow feet, next pitch.
His pattern is that a bad at-bat rides out onto defense — he'll strike out and then boot the next routine grounder because his head is still at the plate. If you see it, the message from the stands is calm, not corrective: step off, breathe, next pitch. He already knows the swing didn't work; what he needs is to clear it.
You're not his coach today, you're his ride and his calm. Cheer the effort and the good process — the tough two-strike out that he hit hard the other way is a win even if it's caught. Don't coach from the bleachers; his coach and the third-base coach have that. He plays looser when he knows you're just there to watch him compete.
Let him lead. If he wants to go at-bat by at-bat, go with it. If he's quiet, let it be quiet. Whatever the day was, the one line that always works: "I loved watching you play today." Leave it there.
