Marlins Can Win If…

• Sandy Alcantara delivers a quality start. Against a struggling Rockies lineup, the ace has the chance to set the tone.
• Their contact hitting holds up. Miami ranks 8th in batting average (.250) and 7th in doubles (253), showing they can generate steady offense.
• Key bats keep producing. Agustín Ramírez leads with 20 home runs, and role players like Javier Sanoja and Heriberto Hernández add depth.

“We know we can manufacture runs and keep pressure on,” Marlins players have emphasized during their recent stretch.

Rockies Can Win If…

• Tanner Gordon repeats his last outing. He struck out nine Padres across six strong innings, and a similar performance would give Colorado a real shot.
• The lineup provides power. With Hunter Goodman (30 HR, 87 RBIs) and Mickey Moniak coming off a big game, the Rockies have the bats to push back.
• They capitalize on Coors Field’s hitter-friendly dimensions. A fast start at home could flip the momentum of the series.

“We have players who can deliver in key spots,” Rockies staff stressed after Moniak’s three-RBI game.

Key MLB Betting Trends

The Lean

Pick: Marlins Moneyline (−173)
Projected Final Score: Marlins 6, Rockies 4
Total Lean: Under 10.5

Reasoning: Miami’s recent form and Alcantara’s steadiness make them the sharper side. Colorado has power threats, but their pitching staff (last in ERA) has been unreliable all season. Coors usually pushes overs, but both teams’ shaky lineups point toward an under lean with double-digit totals.
