Player Prop #2: Arizona Diamondbacks Under 3.5 runs at -110 / 58% — Multiple key ARI bats listed out combined with Mariners home pitching metrics support the lower total.
Player Prop #3: Seattle Mariners Under 4.5 runs at -105 / 55% — Recent road and home splits show suppressed scoring when facing similar bullpen situations.

Public and money percentages align on the Mariners side while line movement remains stable, confirming the market consensus. Injuries to multiple ARI regulars and Seattle’s recent win streak create a measurable edge for the home team.
