Whether or not the M's season would be resurrected by a managerial change, I don't know.
But the M's are WAY too comfortable with underachieving. There's a lot of hand-wringing among the press and fans, but the players echo their manager's "back of the baseball card" assurances that this team somehow will just start playing up to it's capability. They've played so "inevitably" for so long that even if they do it is too late.
They will have to go from underachieving to overachieving to get to the postseason, this despite the mathematical assurances that they aren't that far out of the race. As any experienced baseball follower will tell you, it's not a matter of how far behind you are, it's also how many teams are between you and the prize. The problem becomes this-- for every loss by one team ahead of you that helps you, there is an equal and opposite win for another. You pile up enough teams ahead of you that at some point the necessary collective losses for you to pass them all simply aren't there.
But hey, you gotta try. I like Lloyd personally. And I'm not convinced that making a change is going to accomplish much in the long haul. But fire the guy. Try SOMETHING. This season is the kind that induces stomach-emptying.
Come to think of it, I wonder if Cano's stomach troubles started when at some point he realized that all the things people warned him about regarding the Seattle Mariners was true and he was stuck with them for ten years.
