The Seattle Mariners head to South Florida for a Tuesday night matchup against the Miami Marlins at loanDepot park, with first pitch scheduled for 6:40 PM ET on July 7, 2026. Miami will send right-hander Max Meyer to the hill, while Seattle has yet to announce a confirmed starter. The Mariners are rolling out a lineup built around familiar core pieces — Cal Raleigh batting cleanup, Randy Arozarena hitting second, and J.P. Crawford leading things off from the three spot — making this a meaningful test against a young Marlins arm with legitimate stuff.

Pitching Matchup: Max Meyer vs. TBD

Max Meyer is the story on the mound tonight. The young Marlins right-hander has shown the kind of arm that makes scouts pay attention, and facing a Mariners lineup at full strength is exactly the kind of challenge that will tell us something real about where he is as a pitcher in 2026. Seattle has not confirmed a starter as of this writing, which adds a layer of uncertainty heading into the night. However the M's piece together the pitching, the bullpen depth and sequencing will matter in a road environment where Miami's younger players will be looking to make a statement.

Seattle Mariners Starting Lineup at Miami

• J.P. Crawford — 3B
• Randy Arozarena — LF
• Dominic Canzone — DH
• Cal Raleigh — C
• Josh Naylor — 1B
• Luke Raley — RF
• Cole Young — 2B
• Victor Robles — CF
• Colt Emerson — SS

Miami Marlins Starting Lineup

• Liam Hicks — DH
• Kyle Stowers — 1B
• Otto Lopez — SS
• Xavier Edwards — 2B
• Griffin Conine — LF
• Owen Caissie — RF
• Jakob Marsee — CF
• Joe Mack — C
• Javier Sanoja — 3B

Keys to Watch for Seattle

• Cal Raleigh in the middle of the order. Raleigh hitting fourth is a statement of trust. How he handles Meyer's stuff early will set the tone for the entire lineup.
• Colt Emerson at shortstop. The young prospect batting ninth gives the Mariners a look at what Emerson can do against a legitimate pitching prospect in Meyer. Both players have futures — tonight they collide.
• Cole Young's development at second base. Young continues to get regular reps in this lineup. His plate discipline and contact approach against a power arm like Meyer is worth monitoring.
• Seattle's pitching situation. Without a confirmed starter, the M's may be looking at a bulk reliever or opener scenario. Whoever gets the ball needs to keep Miami's lineup — particularly the top three of Hicks, Stowers, and Lopez — off the bases early.

Prediction

This is a winnable road game for Seattle, but Meyer presents a genuine challenge. The Mariners lineup has enough talent from top to bottom — Crawford setting the table, Arozarena providing thunder, Raleigh anchoring the middle — to put runs on the board at loanDepot park. The unknown starter is the wild card. If the M's can get five or six innings of quality work out of whoever opens the game, the lineup should do enough damage against Meyer to come away with a victory. Call it Seattle 4, Miami 2.
