I don't think Davey would lie about it in the presser.
Davey is not the type to lie in a press conference but he is less likely to have called that play so I conclude that this is one of those rare times that he lied. he is too smart to have called that play and Espinosa is just dumb enough to have done it on his own. I mean, if he called a bunt, was it supposed to be a squeeze, safety squeeze, bunt the runner at second over, or bunt for hit. Not the first two, because Morse never got the memo. Not the third, because Davey isn't that dumb. No, Espinosa was bunting for a hit, on his own.
