Can we stop reading too much into this? The Jays promoted Stroman and with roster juggling and injuries in AAA were an arm short there. That to me means two things. One, they intend to keep Stroman up with the team, and two Sanchez was the best of all the options to make that jump. If it was just for a start or two, I'd assume they would have either covered it internally or brought Walters up for a start or two in AAA.
