Something to keep an eye on when the Blue Jays and Yankees meet again: everybody on both teams thinks everybody on the other team is stealing signs or tipping location, which can lead to some nastiness. As Yankees closer Andrew Miller said: “There’s a lot going on out there.”
The Yankees are one of the teams that uses multiple signs at the Rogers Centre even when there’s nobody on base, out of fear that somehow, someone somewhere in centre-field is stealing something. This all goes back, of course, to assertions from the Chicago White Sox contained in a 2011 ESPN The Magazine article, and it’s had a remarkable shelf-life considering the changeover in personnel the Blue Jays have undergone.
