Mariners vs Tigers Prediction
Detroit was able to steal game one in extra innings and even though they lost game two, they now have the home field advantage in the series. The Tigers have been very bad at the plate over the last month, but their pitching staff has been elite in the postseason. Seattle has scored three runs or fewer in five straight games, but they have one of the better lineups in the American League. I know we have seen five runs scored in each of the first two games in this series, but I think both offenses will wake up here, as I don’t like the pitching matchup or the Detroit bullpen. Take the over here.
