The upcoming game between the Seattle Mariners and the Houston Astros features two strong starting pitchers, Bryan Woo for the Mariners and Hunter Brown for the Astros.

The Mariners also recently secured a shutout win against the Royals, displaying their pitching depth and defensive capabilities.
Taking into account the pitching strengths and recent trends, the game has a high likelihood of staying below the set total of 7.5. A projected final score that aligns with this would be the Astros winning 3-2.
