4. Due to rain, any other weather or field condition, or darkness, games will be official after 3.5 innings if the home team is winning and after 4 innings if the game is tied or the home team is losing. Postponed games will be replayed from the beginning of the game at a later date.

5. The pitching style is standard arc, or modified. High arc or windmill pitches are not allowed. Umpires should be informed before games about our rule: a pitch without an arc (flat) should be called a ball. The pitch must have a "hump."
