Toronto Blue Jays vs. Seattle Mariners Prediction
I’m on the Mariners in this one. Gausman had a great start last time out, but that was at home, where Gausman has been more effective this season. On the road, Gausman has had a lot of issues, and with how well this Mariners team has been hitting, I don’t see those issues going away here. The Mariners are just flat out playing the better baseball, and I think that they have an edge in the bullpen as well here, so give me Seattle to draw first blood in this series.
