I kinda get it. The tying run had just moved to 2nd, first was open, and Marshall had only faced two hitters. Putting Pujols on allowed him to bring Hendriks in.
I think you're right. But it's interesting that it worked out that way. Twitter is basically just shouting your thoughts into the ether. You rarely get anything resembling a productive conversation, which was already rare in the messaged board format.
