First and Third Base Coaches Have to Actually Stay in Their Boxes Now, and Stop Trying to Be Sneaky - Bleacher Nation

"It's such an egregiously ignored dictate that I think a lot of folks don't even realize there's a painted box over there by first and third base where the associated coaches are supposed to remain. Moreover, even to the extent we did realize that, I think we almost universally assumed that it was a matter of safety - we've seen those coaches nearly crushed by a rocket foul ball,"

"All that stuff can be true, but there's an element to the discussion that has been missing from public discourse: spycraft. MLB's owners have just voted on a rule change - well, a rule enforcement - that will require first and third base coaches to ACTUALLY stay in their box until after the pitch is thrown. No more casual moving up and down the line. You get a warning, and then you get an ejection."

A new enforcement will require first and third base coaches to stay inside the painted coaches' boxes until after the pitch is thrown. Owners approved warnings followed by ejections for coaches who repeatedly leave the box early. Many coaches historically positioned themselves outside the box, often justified as a safety precaution. The enforcement targets on-field movement used to gain visual angles on opposing pitchers to detect tipping signals—spycraft rather than safety. Teams already use scouts and video to find pitch-tipping, and the rule aims to halt in-game positioning maneuvers for competitive intelligence.
