I think I heard Youk saying that play was on Casas. And this is whatever, but I'm pretty sure Casas started charging as soon as he saw the batter show bunt, which is what you see a 1B do a lot of the time in that situation. It's not like he knew the thing was about to be bunted directly back to Sale. Doesn't the 2B have to start moving to cover first as soon as he sees the batter showing bunt and the 1B charging? I might be wrong.
