There does seem to be a strange coincidence that it happened with a guy on third, but still idk...
Kinda reminds me though, for some of you hardcores with a good memory. I was watching a Blue Jays game (not too long ago 2months max) and I think it was Bautista in the box or maybe JD, they were extending their arm out over the plate pre-pitch before the catcher threw it back to the pitcher and twice the catcher thought better of forcing a throw to the pitcher until the arm came down, he finally threw it back and then suspiciously looked at the batter. Anyone remember this?
To me it looked like the catcher thought it was intentional, so maybe it's one of those "cheap trick" kind of plays that don't happen all the time but the vets know about?
