Paxton struck out nine in seven outstanding innings, and Nelson Cruz and Guillermo Heredia homered to lift the Mariners to an 8-0 victory over the Detroit Tigers on Wednesday. Paxton (3-0) allowed four hits and a walk in a dominant performance against a Detroit team that had scored 32 runs over its previous two games. Daniel Norris (1-2) allowed four runs and nine hits in four-plus innings. Seattle opened the scoring with three runs in the second, including a two-run homer by Heredia that made it 3-0. The Mariners chased Norris in the fifth and scored a run when reliever Shane Greene walked Ben Gamel with the bases loaded. Cruz's two-run shot made it 6-0 in the sixth. Hernandez went on the 10-day DL with right shoulder inflammation, and OF Mitch Haniger joined him because of a strained right oblique.
