Diamondbacks vs Marlins Picks

Tyler Phillips Over 3.5 Strikeouts (+115 at DraftKings): Phillips averages 6.23 strikeouts per nine innings. He faces an Arizona lineup that has accumulated 469 strikeouts this season. Clearing a threshold of four punchouts is a highly probable outcome based on his recent workload.

Corbin Carroll to record 2+ total bases (-115 at bet365): Carroll hits .284 with a .929 OPS and leads his squad with 42 runs scored. He provides reliable extra-base hit upside.

Otto Lopez to record a hit (-320 at bet365): Carroll hits .284 with a .929 OPS and leads his squad with 42 runs scored. He provides reliable extra-base hit upside.

ARI Diamondbacks vs MIA Marlins Prediction

• Best Bet: Marlins ML (-112 at Caesars)

The pitching data reviewing the MLB probable pitchers points toward a distinct advantage for the home team.

Miami trots out Tyler Phillips, who has delivered highly effective innings this season, whileArizona will hand the ball to veteran right-hander Merrill Kelly to stabilize their rotation.

Kelly has encountered significant difficulties throughout 2026. He enters this start with an elevated 5.71 ERA and a 6.12 FIP. His inability to generate swings and misses, evidenced by a 5.71 K/9, allows too much traffic on the basepaths.

He issues nearly four walks per nine innings, which constantly pressures his defense.

Phillips brings a much steadier profile to the mound. Through 43.1 innings of work, he holds a 3.12 ERA and limits opponents to a .242 batting average. Over his last 10 appearances, Phillips has registered a sharp 2.39 ERA. He pitches to contact efficiently while managing his walk rate at 3.42 BB/9.

Diamondbacks vs Marlins Team Stats

The Marlins produce consistently in their home ballpark. They rank tied for seventh in home batting average (.251) and apply tremendous pressure by stealing 1.05 bases per game. This environment perfectly suits a contact specialist like Lopez.

Conversely, the Diamondbacks struggle to generate road offense. They plate just 4.19 runs per game as visitors. Their 86.3 mph average exit velocity on the road sits 30th in the majors.

This lack of hard contact reinforces my confidence in Phillips executing his game plan, allowing the Marlins to win.
