Seattle Mariners probable pitchers & starting lineups vs. Miami Marlins, April 27

The Seattle Mariners are staring down their fourth consecutive rubber match — and once again, they’re on the cusp of another series win. Winners of five straight series coming into Sunday, the Mariners have a chance to make it six in a row with a victory over the Miami Marlins, a team that has proven to be scrappy as expected.

Seattle was dealt an early blow in the opener when Logan Gilbert exited after just three innings with an injury, and they couldn’t recover in a tough 8-4 loss. But they punched back in a big way Saturday night, unleashing 14 runs in an offensive explosion that reset the tone for the series. Now, with momentum on their side, the Mariners will look to finish the job at T-Mobile Park.

Here’s a look at the starting pitchers, projected lineups, and everything you need to know ahead of today’s series finale, with first pitch at T-Mobile Park scheduled for 1:10 p.m. PT.

Starting for the Mariners: Logan Evans, RHP (0-0, 0.00 ERA)

It’s a big day for Logan Evans, who will be making his major league debut for the Mariners. A 12th-round pick in the 2023 MLB Draft, Evans has ascended through Seattle’s minor-league system at an impressive pace, earning his call-up after a strong start at Triple-A Tacoma. Over five starts this season, Evans posted a 1-1 record with a 3.86 ERA, striking out 23 batters across 25.2 innings.

Evans isn’t the type of pitcher who’s going to light up the radar gun, but he fits the Mariners' mold perfectly: he pounds the strike zone, stays one step ahead of hitters, and lets his arsenal do the talking. His bread-and-butter is a low-90s two-seam fastball that he pairs with a four-seamer, cutter, curveball, slider, and changeup — giving him a deep and well-rounded mix that can keep hitters guessing.

Command and pitch sequencing are Evans' biggest strengths. He’s not afraid to work all quadrants of the strike zone, and his willingness to mix speeds will make him a tough assignment even without overpowering stuff.

Making your big-league debut always comes with jitters, but the Mariners couldn’t have asked for a better landing spot for their young right-hander: a home start against a rebuilding Marlins lineup in a non-divisional game.

Starting for the Marlins: Max Meyer, RHP (2-2, 2.10 ERA)

Max Meyer has wasted no time reminding everyone why he was once one of the most highly-touted arms in the Marlins' system. The 26-year-old righty has come out of the gates firing to start 2025, posting a sparkling 2.10 ERA — good for eighth-best in the National League — across his first five starts. Meyer’s also racked up 41 strikeouts over 30 innings, placing him sixth in the NL, and establishing himself as a tough customer for any lineup.

Meyer leans heavily on his signature slider, throwing it over 40% of the time, and backs it up with a four-seam fastball that can touch 95 mph. He’ll also mix in a changeup, sinker, and an occasional sweeper, keeping hitters guessing and working both sides of the plate.

For the Mariners, the key to success will be making solid, early contact. While Meyer excels at missing barrels, when opponents do connect, they tend to square him up — hard. His 94.0 mph average exit velocity allowed ranks in the bottom 1% of all MLB pitchers. In other words, if Seattle can stay disciplined, avoid chasing the wipeout slider, and put the ball in play, they’ll have a real shot at getting Meyer out of rhythm and out of the game.

What's at Stake?

Interleague matchups like these are often treated as bragging rights this early in the season — but for the Mariners, today’s game carries some real weight. Seattle enters Sunday tied with the Texas Rangers atop the AL West, and with injuries starting to mount, every win is becoming increasingly crucial.

The loss of Logan Gilbert to the 15-day IL with a right forearm strain is a serious blow, and with George Kirby still not expected back until late May, the Mariners are entering a critical stretch. They’ll be leaning heavily on young, promising arms to patch the rotation — talented pitchers, for sure, but still ones who are developing at the major-league level.

So far, Seattle has shown impressive resilience, finding ways to grind out wins even as injuries have tested their depth. Extending their series win streak to six today wouldn’t just be another notch in the belt; it would be a statement that this team is built to survive the ups and downs of a long and grueling baseball season.
