White Sox vs Diamondbacks MLB Betting Preview
This game triggered one of our Action PRO betting systems, powered by Evan Abrams:
The Chicago White Sox head to Chase Field as road underdogs against the Arizona Diamondbacks in this interleague clash. The White Sox will be listed as plus-money dogs on the moneyline, giving bettors the plus pricing the system loves in these interleague matchups.
This matchup lines up perfectly with Evan Abrams' "Road Dogs Interleague" system.
Chicago is the visiting team from the American League, playing an interleague game in a National League park, and coming in as the clear moneyline underdog. Markets and the betting public consistently overrate home teams and intra-league familiarity in these cross-league games, creating value on the road dog.
The system has shown steady profitability since 2016 by exploiting exactly this inefficiency. Even though these road interleague underdogs win just 43.3% of the time, the plus-money payouts have produced a solid 4.6% ROI and have been profitable in each of the last five full seasons.
Pick: White Sox ML
