In this Boston Red Sox vs Seattle Mariners Prediction, the Mariners are coming as -185 home favorites. Both teams have almost identical overall records but the Mariners are above average at home, while the Red Sox are below average on the road. Both teams are in very good form, but the Mariners are playing their fourth straight game at home, while the Red Sox had to travel to Seattle all the way from the East Coast last night.
Gilbert has been excellent for the Mariners this season, and his advanced stats indicate that he is even better. Giolito on the other hand, might be looking better lately, but he has been terrible throughout the season. Both teams have similar bullpens, so I will focus on the first 5 innings of the game, where the Mariners have the huge advantage, so I will take the Seattle Mariners on the runline in the first 5 innings of this game.
