The more I look, the more I like the past few days.
If (and it's an if), Sanchez has to go to the pen, the Jays now have Hutch and Feldman as potential replacements. I would take Feldman over Chavez every day of the week.
And they also have another 30 days to make a trade for somebody to replace Hutch/Feldman.
After today, they have two solid options to move into the rotation to replace Sanchez (if necessary) and they have time to replace the bullpen production of the guy going into the rotation.
