What is the consequence of a player having an illegal contact with a fielder while running the bases?

When a player illegally contacts a fielder while running the bases, the most common consequence is that the player is declared out. In softball, players are required to avoid interfering with fielders who are attempting to make a play. If a runner makes illegal contact—whether through physical obstruction or hindrance—this often results in the runner being ruled out. This rule is primarily in place to ensure fair play and maintain the safety of all participants on the field.

In situations where contact might occur, umpires will assess whether the contact was indeed illegal and if it interfered with the fielder's ability to make a play. If it is determined that interference took place, the runner's out status serves as both a penalization for the offense and a corrective measure to uphold the integrity of the game.
