Mariners vs. Tigers Pick
Money Line Pick for Mariners vs. Tigers
- Seattle Mariners ML (4 Units)
The Mariners have won six of their last seven road games, while the Tigers have lost eight straight home games. Seattle has the edge here because they’ve hit the ball well against right-handers, and they’re going up against Mize, who was shaky on the mound in recent home starts, giving up six runs in his last two road starts. He gave up six runs in two starts against the Mariners this season and will have a hard time slowing them down.
Detroit won’t be as successful offensively because they’ve struggled against right-handers so far, and they’re going up against Miller, who has done well on the mound in recent road starts, giving up five runs in his last two road starts. He didn’t give up a run in three starts against Detroit and will keep their offense in check. Take Seattle on the money line.
Over/Under Pick for Mariners vs. Tigers
