I missed this tidbit from the same interview:
In Marcus Stroman, R.A. Dickey, Marco Estrada and J.A. Happ, the Blue Jays have four of the members of 2016′s starting rotation set. Who will man that final spot remains cloudy, but Gibbons did shed some light on the situation Monday.
“We’re going to stretch (Aaron Sanchez) out and see how that all plays out in the spring; decide whether we’re better as a team with him in the rotation or in the bullpen,” the Blue Jays skipper said. “And then of course you have (Drew Hutchison) and you have Jesse Chavez. So there’ll be some good competition.”
