On behalf of both Wood parents: Home plate the rose bush at the porch. First base the tomato plants, second base the pine tree and third base the worn out patch of dirt next to the fence. Wiffle ball and kickball for hitting and baserunning. Race you to the pole = 60 training. Wrestling with your neighbor or cousin = strength and conditioning. Hitting rocks into the creek with a stick = hand eye coordination. Playing whatever sport was in season (plus a healthy dose of dodge ball with the hard yellow balls) = agility training.
Also, a game we made up called balls and strikes with tennis balls and a tree branch.
Also, playing on whatever team in whatever position was in our home town and not changing teams chasing a spot at SS.
