Seattle enters this game fully healthy while Arizona's Nolan Arenado is day-to-day with a groin injury and was already scratched earlier this series. The pitching matchup heavily favors Seattle, with B. Miller (2.25 ERA) squaring off against Merrill Kelly (5.25 ERA), giving the Mariners a decisive edge on the mound. Taking Seattle on the run line at +141 price represents strong value given the injury and pitching advantages stacking in their favor.
