Blue Jays vs Mariners Prediction 

Seattle comes into this matchup with a chance to advance to the World Series with a win, and they are 2-0 on the road so far in this series. The Mariners had a huge eighth inning in game five to get the win, but they really haven’t played great in their last three games. Toronto needs to find a victory in this game and they are normally very good at home, as they went 54-27 at home during the regular season. I do think Seattle has the pitching advantage with Gilbert on the mound, but I think Toronto will find a way to get the win at home. Take the Blue Jays here.
