Seattle Mariners vs Miami Marlins Picks and Predictions April 26th 2025

Miami’s Agustin Ramirez Sparks Marlins’ Resurgence in Seattle

Agustin Ramirez might just be the unexpected star the Miami Marlins needed.
With the team battling injuries behind the plate, the rookie has burst onto the MLB scene with incredible energy — and a bat that refuses to cool down.

Friday night, Ramirez added another chapter to his fast-growing legend, smashing his first major league home run — a 406-foot rocket — to help the Marlins beat the Seattle Mariners 8-4 in the series opener.

Agustin Ramirez: Immediate Impact at the Plate

Through just three MLB games, Ramirez is batting 7-for-10 with:

• Four doubles
• One home run
• Three RBIs
• An astronomical 2.150 OPS

Acquired last July from the Yankees in the deal for Jazz Chisholm Jr., Ramirez wasted no time proving he belongs.
He was called up Monday after injuries to catchers Nick Fortes and Rob Brantly left the Marlins scrambling for depth.

Notably, Ramirez isn’t just a stopgap — he’s already the Marlins’ designated hitter and batted cleanup Friday night, showing how much confidence McCullough has in the young slugger.

Miami Marlins: Finding Momentum

The Marlins’ 8-4 win over Seattle on Friday marked their fourth victory in five games, a sign that Miami might be settling in after a rough start to the season.

• Jesus Sanchez homered.
• Miami scored six unearned runs with two outs in the fifth inning.
• Connor Gillispie and the bullpen held the Mariners at bay after the big inning.

The offensive outburst was particularly encouraging considering the Marlins have struggled at times to string hits together this season.

Seattle Mariners: Dealing With New Challenges

Friday’s loss wasn’t the only bad news for the Mariners.
Ace Logan Gilbert, who threw three perfect innings to start the game, left early with right forearm tightness — an injury that immediately raised alarms.

An MRI is scheduled for Saturday, and Seattle will anxiously await results.
Gilbert, who led MLB in innings pitched last season (208 2/3), has been a rock of durability since his debut — making this injury especially concerning.

Mariners’ Power Shows Flashes

Despite the loss, the Mariners showed they still have pop:

• Dylan Moore and Jorge Polanco each hit solo home runs.
• Seattle continues to flash solid power, even in defeats.

However, the Mariners have now lost the opener in four straight series, forcing them to once again attempt to rally from behind.

Saturday’s Pitching Matchup: Gillispie vs Castillo

Saturday night’s game at T-Mobile Park will feature an intriguing pitching battle:

• Connor Gillispie (0-2, 6.75 ERA) for Miami
• Luis Castillo (2-2, 4.44 ERA) for Seattle

Connor Gillispie: Seeking First Career Win

Gillispie is still finding his footing in the majors.
Although his raw stuff has been impressive at times, inconsistency has hurt him, particularly with command and limiting big innings.

Saturday marks his first career appearance against the Mariners — and a prime opportunity to showcase his growth.

Luis Castillo: Dominance Against Miami

Meanwhile, Luis Castillo has a history of success against the Marlins:

• 5-1 career record
• 2.20 ERA
• 51 strikeouts in seven appearances

Castillo’s ability to command both sides of the plate with a mid-90s fastball and devastating changeup makes him a nightmare matchup for young, aggressive hitters like Ramirez.

If Castillo’s stuff is sharp, Miami’s hitters could be in for a long night.
