yep, stat sheets don't mean much in high school where you play so few games agaisnt such a variety of pitching (poor to outstanding).
For the most part I've got a pretty good inkling that other coach isn't going to put his best hitter in the 8 hole...
You get to know your league pretty well, but more by seeing what they do than looking at any kind of statistic.
We do have a pretty good idea of the 1st and 3rd stuff our opponents use (unless they have a new coach) because i've been around forever and seen all these guys, and coached some of them in my area)...
We also try to get an idea of who most likely will run by seeing what they did in jv or you can get this by asking the kids; they know those guys or remember who can fly or who can't from some 8th grade track meet or summer games...
But the main question; to get them ready for a game, is the same as any game; throw strikes; field the baseball; leave the crummy pitches alone and crush the good ones.
