I'll go further. The decisive turning point will be when, in the middle innings, Japan has the bases full, no outs, with Ohtani - Yoshida - Murakami coming up, and the US not only wiggles out of it but then Turner -Mookie -Trout go back to back to back the next half inning to grab a lead that the US never relinquishes.
the US would have to decode their signs as well.
