The Miami Marlins head to Phoenix for a Tuesday night affair at Chase Field, with first pitch scheduled for 9:40 PM ET on September 15, 2026. Right-hander Janson Junk gets the start for Miami against Arizona's Michael Soroka in what shapes up as a late-season regular season contest between two National League clubs. It's a road trip the Marlins need to make count as the 2026 regular season winds toward its final weeks.

Starting Pitching Matchup: Janson Junk vs. Michael Soroka

Janson Junk draws the assignment for Miami in this one. The right-hander has carved out a role in the Marlins rotation and will need to navigate a Diamondbacks lineup that presents genuine challenges top to bottom. Soroka gets the ball for Arizona — the veteran righty has had a winding career path, and this is a chance for him to deliver a quality start at home with the regular season in its final stretch.

Arizona Diamondbacks Lineup to Watch

The D-backs present a formidable order that Junk will need to manage carefully. Here's how Arizona lines up:

• Lars Nootbaar, LF — leads off and sets the table
• Ketel Marte, 2B — one of the most dangerous hitters in this lineup
• Gabriel Moreno, C — a quality bat behind the plate
• Geraldo Perdomo, SS — slotted in the cleanup spot
• Corbin Carroll, RF — an athletic threat on the bases and at the plate
• Nolan Arenado, 3B — a Hall of Fame caliber glove with pop in his bat
• Jesús Sánchez, DH — a familiar name to Marlins fans, now in Arizona's lineup
• Pavin Smith, 1B
• Jordan Lawlar, CF — rounds out the nine

That middle of the order — Marte, Moreno, Perdomo — is where Miami's pitching staff will face its stiffest test. Junk cannot afford to let that trio beat him with traffic on the bases.

Keys to the Game for Miami

Junk Must Work Efficiently Early

Chase Field can be a hitter's environment, and the Diamondbacks' lineup has enough contact ability and power to make a long outing difficult for any starter. Junk needs to establish his command early, stay out of deep counts, and give Miami's bullpen as much rest as possible heading into the late innings.

Marlins Offense Needs to Make Soroka Work

Miami's lineup will need to grind at-bats against Soroka and avoid letting him settle into a rhythm. Getting into Arizona's bullpen early gives the Marlins their best chance in this one. Plate discipline and working counts will be essential on the road.

Handle the Middle of the Arizona Order

Marte and Carroll are the names that can change a game in a single swing. Junk and Miami's battery must have a clear plan for both hitters, especially with runners aboard. One crooked inning against this lineup can snowball quickly.

Prediction

This is a tough road assignment for Miami. The Diamondbacks' lineup is deep, and Chase Field isn't a friendly park for visiting pitchers. Junk is capable of putting together a solid outing, but the Arizona order — anchored by Marte and Carroll — presents a real challenge. Look for this to be a competitive game, but give the edge to the home side. Diamondbacks 5, Marlins 3.
