What is the ruling if a runner maliciously contacts a fielder without the ball?

When a runner maliciously contacts a fielder who does not have the ball, the appropriate ruling is that the runner is out and ejected from the game. This decision is based on the principle that players are expected to compete within the rules and spirit of the game. Malicious contact is a serious offense as it endangers the safety of the fielder and undermines the integrity of the sport.

In this context, the ejection serves as both a punishment for the specific act of maliciousness and a deterrent against similar behavior in the future. Upholding a standard of sportsmanship is crucial in maintaining a safe and respectful environment for all participants. Such a ruling demonstrates that aggressive or unsportsmanlike actions will not be tolerated and reinforces the expectations players must adhere to while on the field.

The other options do not reflect the seriousness of the act. Allowing the runner to be declared safe or simply receiving a warning does not address the aggressive nature of the contact and fails to provide appropriate consequences. Not assessing any penalty compromises player safety and the spirit of fair play, which are core principles in sports.
