The Mariners have shown a strong offensive performance, scoring multiple home runs in their previous match against the Astros. This offensive momentum, coupled with the Astros’ ability to score, sets the stage for a high-scoring game.

The Mariners’ last two games against the Astros have resulted in a total score exceeding 8 runs, indicating that the offenses have been active when these teams meet. Given the current form of both teams and the capabilities of their lineups, the over appears to be a solid choice. Projected Final Score: Mariners 6 – Astros 4, reflecting the likelihood of both teams capitalizing on their offensive opportunities. This would comfortably cover the over 7.5 total.
