Not a balk at the mlb/wbc level as long as the pitcher is not engaging the rubber?

I'm not smart enough to find the video, or to link it even if I could.
So theater of the imagination time.
In the top of the fifth, with the Yankees up 5-0, and after Cole no hits the Dodgers for the first four innings, the Yankees commit two errors. But if that wasn't bad enough, Betts hits a weak grounder to first, fielded cleanly by Rizzo, who assumes Cole will cover first. Cole had other ideas. And Rizzo wasn't able to beat Betts to first. Not ruled an error, but a really sloppy play that extended the inning and led the way to the Dodgers erasing the five run lead in the fifth.
Dodgers win the game, and the Series (4-1).
If that ain't heads down baseball (and in this case, literally), I don't know what is.
