Preview: Miami Marlins at Arizona Diamondbacks
The Arizona Diamondbacks host the Miami Marlins on Tuesday night in a matchup our statistical model projects to be decided by a narrow margin. Drawing on a 25-game sample of recent scoring form for both clubs, the model projects a final score of Arizona 5, Miami 4, landing just above the game's 8.5 total.
That tight projection drives our position on the run line. When we published, we took Miami at +1.5 on DraftKings. With Arizona projected to win by only a single run, our numbers show a 1.43-point edge toward the road underdogs keeping the final deficit within that 1.5-run cushion.
That discrepancy earns Miami +1.5 a high rating from the model. While statistical projections capture probabilistic edges rather than certainties, the baseline scoring data suggests Miami is well positioned to cover the tracked spread in a close contest.
How the model got here
Model projects 4–5, a 0.1 margin against a market number of 1.5 — a 1.43-point edge toward the road side. Based on 25 and 25 games of scoring form.
