Orioles vs Mariners Prediction 

Baltimore comes into this series with a little momentum, which is something they haven’t had much of this season. The Orioles are 10-19 on the road this year, while the Mariners are 16-14 at home. Seattle has struggled over the last ten days, but they have won two games in a row. The Mariners are starting Kirby, who has allowed 11 earned runs and 13 hits over his first two starts (8.2 IP). The Orioles are going with Sugano, who has allowed two earned runs or fewer in three of his last five starts. I know Kirby is going to eventually settle in, but I have to fade him until I see improvement. Take Baltimore on the road here.
