The back fields are a weird experience. Last time I was there was when Wilkin Hernandez saved my son's life by jumping over the wall and bringing back a HR ball that I was foolishly trying to catch with my son on my shoulders. The ramifications of the ball hitting the kid instead of my hands which I was using to hold him were lost on gormless me.
Back then, you could back then just go back there and watch drills and scrimmages they had going on. You'll see a lot of infield scenario practices. The pitchers have to be HERE when the ball goes to RF and there is a runner on second. The runner being drilled on how far to lead off on the fly ball, etc. They are experienced at Baseball but they do the drills to make it all second nature. Its of great interest if you are a youth sports coach or otherwise a nut about the game, but your non-baseball addict wife or kids might be bored out of their minds.
