I rarely work any tournaments in the summer other than under USA Softball. And I typically receive $40 per game for those. The vast majority of those games are time-limited until we get to the final, and even then we often play with a clock.
I have also worked some college showcases where the organizers pay between $35 and $45 per game. Those are typically 65 to 80 minute contests, finish the batter.
I cannot recall ever getting $50 or more for travel ball.
