Seattle Mariners vs Detroit Tigers Prediction, Odds and Picks for Today, 07/12/25

I favor the under on the posted game total in Saturday’s matchup between the Seattle Mariners and Detroit Tigers. George Kirby and Casey Mize are both starting pitchers I am fond of, and I expect them to both perform well today in a pitcher-friendly park. Kirby is the starter I am less confident in today, as his start to the year was postponed due to injury and he is still finding his footing. Strikeout production had not been there for him very much outside of his explosive outing against the Angels, but Kirby did register 9 Ks against the Pirates in his last start. That outing resulted in 6.1 innings of scoreless ball after back-to-back 6-inning, 1-run performances.

Mize has been strong all season long for the Tigers rotation, providing them with a 2.63 ERA across his first 85.2 innings pitched. This includes a 7-inning start against Cleveland in his last start where he held the opposition scoreless. Mize has allowed no more than 2 earned runs in any of his last 6 starts and no more than 3 in any of his last 9. Seattle and Detroit are both competent offensively, but both teams also have strong bullpens behind these talented starters, and I lean towards the under in this game as a result.

Seattle Mariners vs Detroit Tigers prediction: Under 7.5 (-105) available at time of publishing. Playable to -110.
