Blue Jays vs Mariners Prediction

I’m on the Blue Jays in game one. The extra innings game for Seattle completely threw off the plan as it was supposed to be Luis Castillo here, but three starters were used. It’s the perils of having all hands on deck, but it was necessary for Seattle in that game. The problem is Miller got roughed up by the Blue Jays already this season and Toronto’s full of confidence after that series win against the Yankees.

Kevin Gausman’s been solid in the postseason, and this is why the Blue Jays battled so hard for that AL East title and home field because they’ve been a much stronger team at home this season. I like Toronto to draw first blood here, so give me the Blue Jays.
