That thing where the Mets sat Marte? And they didn't use him to pinch-hit medium-late in the game when they could have used him? Because they seemingly wanted to give him a "full" day off? But then they pinch-ran-him the ninth? And he ended up getting caught stealing? And upending their last, best threat? And ending their utterly inconsequential-but-curiously-novel streak of consecutive stolen bases? Well, maybe that wasn't really a thing. But now they're sitting him again. So maybe now it's a thing.
