Yep, I would. Unless injuries or something along those lines happen *knock on wood* it doesn't, he shouldn't be in the rotation come playoff time. I hate buying into this but with how extreme his home splits have been you can't have Estrada over Hutch at home. While I know you may be concerned on Stroman, and it is fair, if he shows he's "got it" again through the minors and majors then he is more than capable of taking over that spot from Estrada.
The only pitcher I could see Estrada taking over is Dickey and that is in part to having Thole in the lineup. If it comes to "crunch" time in a series he may get the nod so not to take Martin's bat and head out of the lineup. He's been turrble when catching Dickey.
