Nah, the Hays play was completely different because it was a rocket shot right at the first baseman, absoultely nothing he could do. Mancini was a just brain fart. You dont take off for second on a bloop that may or not drop in that was barely past the infield dirt. It's just an awful, awful base running mistake and one that Mancini nwoudl certainly atest to that he royally screwed up.
He's typically a heads up player so I'll just chalk that up to an honest mistake, but one that can never, ever happen again. The reason why you freeze on that play or take a step back is for the very reason is if it's caught's a double play. If it drops in and you get thrown out at second, it's only one out.
