Greg Peterson recommends Reds moneyline +105 and Under 9 runs when they host the Mariners. Bryce Miller, Mariners' starter, shows extreme home-road splits in career statistics, sporting a strong 2.73 ERA at home but elevated 4.60 ERA on the road, allowing significantly more HR/9 innings away. Meanwhile, Reds’ pitcher Nick Martinez has excelled since joining the team pre-2024, posting a 3.40 ERA with a solid 3.32 FIP and very low walk and home run rates (0.9 HR/9, 1.2 BB/9). Peterson handicaps the matchup as Reds -106 moneyline, total at 8.4, both indicating clear value to bet Cincinnati and under 9 runs.
