I just don't see what role he'd serve out of the pen. If they are getting blown out early in a game and need somebody to eat some innings guys like Sanchez / Hendriks / Lowe / Hawkins can each give them at least an inning, probably two, and the chances of that happening with Price / Stroman as your #1-2 aren't great. I suppose Dickey is always prone to getting knocked around every now and then, but he's been pitching fine.
They'd simply be better served with the extra bench player who they are more likely to use in a close game, a guy like Pompey who they can pinch run, or an extra defensive replacement or even a bat like Hauge (probably the least likely option). The only purpose Hutch would serve is to potentially go 3-4+ innings in a game the Jays are getting blown out in to help save the pen, but when you're only playing two games in a row and then have a travel/rest day, there's really no reason why everyone in the pen shouldn't be available on any day. They are way more likely to get use out of the extra bench player as opposed to Hutch out of the pen.
