Seattle Mariners probable pitchers & starting lineups vs. Texas Rangers, April 13

Heading into Sunday’s series finale against the Texas Rangers, the Mariners have already clinched the series — but they’re not done yet. A sweep would not only mark Seattle’s first of the 2025 campaign, it would come against a Texas team that entered the series sitting atop the AL West early in the season.

Despite entering the weekend shorthanded and quite frankly viewed as underdogs, Seattle has completely flipped the script. Through two games, the Mariners’ pitching staff has ensured the Rangers bats stay cold. Holding them to just four runs combined. Meanwhile, the offense has caught fire, plating 14 runs across the first two games and riding a wave of momentum into Sunday’s finale at T-Mobile Park.

First pitch is scheduled for 1:05 p.m PT. Here’s a look at the projected starters and what to watch for in today’s matchup.

Starting Pitchers

For the Mariners: Logan Gilbert, RHP (0-1, 2.55 ERA)

Logan Gilbert is still searching for his first win of the 2025 season — but don’t let the win-loss column fool you. The Mariners' right-hander has been sharp to open the year, with little to show for it thanks to limited run support. He’s already been saddled with a tough-luck loss and has come away with no-decisions in his other two outings.

Gilbert’s early-season performance tells a much more promising story. He’s keeping hitters off balance by mixing his pitches well, not relying on any single offering more than 33% of the time. His fastball still anchors the arsenal, but he’s deploying his slider, curveball, and splitter with precision resulting in an absurdly high strikeout rate of 38.5% — a massive jump from last year’s 27.4%.

The road to that elusive first win won’t be easy. Gilbert will go toe-to-toe on Sunday with another top-tier arm.

For the Rangers: Nathan Eovaldi, RHP (1-1, 2.29 ERA)

Nathan Eovaldi will take the mound for Texas on Sunday, looking to play stopper and help the Rangers avoid a sweep at the hands of a surging Mariners squad.

Like Gilbert, Eovaldi thrives by keeping hitters guessing. He features a deep arsenal that includes a heavy dose of splitters, paired with his fastball, curveball, and a cutter that keeps batters honest. The veteran right-hander enters today’s game with an impressive 28.8% strikeout rate, a testament to his ability to generate whiffs across multiple pitch types.

With both starters showcasing elite command and diverse pitch mixes, Sunday’s showdown has all the ingredients for a classic pitcher’s duel at T-Mobile Park.

What’s at stake?

Not only do the Mariners have a chance to sweep the 2023 World Series champions, but they also have an opportunity to claw their way back to .500 after a rocky 4–8 start. With three straight wins already under their belt, Seattle enters Sunday riding a wave of momentum. A win would mark their first sweep of the season and send a clear message that this team, even when short-handed, can punch back against the AL’s best. With an off day coming up tomorrow and a road trip to Cincinnati on deck, the Mariners will look to close out this homestand in style — and set the tone for their upcoming road trip.
