My first Windows Phone app, Little League Coach, has just been released into the marketplace.  If you have ever helped coach a team where every player bats every inning this app should help keep your sanity.  It is a simple application to allow little league coaches to manage the lineup for a game as well as keep track of batter rotation.  As a bonus it tracks pitches and outs during an inning.  Here are a few screen shots from the application.
