Cubs vs Mariners Prediction
The Mariners are 3-1 in their last 4 meetings against the Cubs but have lost two of their last three meetings in Seattle.
In this Cubs vs Mariners Prediction, the Mariners are coming as -115 home favorites. I like the Cubs in this one, as Peterson has been in very good form, having given up two runs or less in six of his last seven starts and has been better on the road. Kade Anderson looked excellent in triple A, but he will face the second-best offense in baseball in his debut and the Mariners’ bullpen has been terrible lately. Take the Cubs to win this one.
