What is the action taken by the umpire when observing a bat that is noncompliant during inspection?

When an umpire observes a bat that does not comply with the regulations during an inspection, the correct action is to file an electronic report. This step is essential as it documents the noncompliance for future reference and ensures that authorities are aware of the situation.

An electronic report allows the governing body of the sport to keep track of noncompliant equipment and facilitates any necessary follow-up actions. This might include investigating the manufacturer of the bat or addressing potential patterns of noncompliance within teams or individuals. By documenting these issues, the integrity of the game can be upheld.

The other actions listed, such as removing the bat from the game or issuing warnings, might be relevant in different contexts but do not reflect the specific procedure of filing an electronic report for noncompliant equipment. Marking the bat for compliance later does not properly address the immediate need for accurate documentation of the issue at hand. Thus, filing a report is the most responsible and procedural action to take when a bat is deemed noncompliant.
