For all we know Katz or Cairo said something and TLR ignored it. That seems just as likely to me as no one saying anything at all. None of us really have any idea what communication did or didnt happen amongst the staff, but ultimately it is on the manager to make the call. The mounting evidence that Gio was running out of gas was pretty apparent to fans watching, so I don't know how it wasn't obvious to the staff in the dugout.
