New Umpire

DG nailed this one. There is no way you can teach this kid what he needs to know in your 15 minutes of time. Focus on the basics and use the KISS principal - Keep It Stupidly Simple - in the army we call it "Make it Lieutenant proof" but I digress.

I would hit
1) play at first - listen for the ball to hit the glove as you watch for the foot hitting the bag.
2) interference - if a runner gets in the way of a fielder fielding the ball, kill it and "talk to me".
3) "Instant replay" in his mind before he makes the call.
4) ACT like he knows what he is doing

and for you - meet with him every half inning to encourage him and/or correct any major screwups. Protect him from the coaches, even if he boots a call.
