The Pittsburgh Pirates and Seattle Mariners will close out their three-game interleague series today, with both teams heading in opposite directions. Seattle, sitting in second place in the American League West, is aiming to lock down a series victory before heading out on a tough road trip.

The Mariners won Game 1 of the series and took Game 2, setting up a pivotal rubber match on Sunday. Meanwhile, the Pirates are languishing at the bottom of the National League Central and are desperately trying to avoid a sweep that would further dampen morale heading into July.

Seattle’s season has been a tale of highs and lows, particularly on the offensive side of the ball. The Mariners have shown flashes of power—ranking sixth in the majors in home runs—but they've also struggled with consistency, especially at home.

That makes every win critical as they try to keep pace with the division-leading Houston Astros. Securing a series win against a struggling Pittsburgh club would give the Mariners a much-needed boost before facing tougher opponents on the road.

Our Seattle Mariners vs Pittsburgh Pirates Prediction

Taking the mound for Seattle is right-hander George Kirby, who enters the game with a 2-4 record and a 4.85 ERA over eight starts. While his overall numbers aren’t overwhelming, Kirby looked sharp in his last outing against the Kansas City Royals, throwing six innings of one-run baseball while striking out five in a 6-2 victory. The Mariners will be looking for a similar performance today to keep the Pirates’ offense in check.

The Pirates counter with Paul Skenes, their highly touted rookie ace who has quickly become must-watch television. Skenes brings not only electric stuff but a growing reputation for poise under pressure.

His ability to dominate opposing lineups early in games has kept Pittsburgh competitive, even when their offense struggles to produce. However, concerns remain about the Pirates' ability to score, especially late in games when opposing bullpens take over.

Expect a low-scoring affair dominated by pitching through the early frames, but if Seattle can capitalize late, they should be able to secure the series win. Pittsburgh's offensive woes continue to be their Achilles’ heel, and that may prove costly once again today. Our prediction for Seattle Mariners vs. Pittsburgh Pirates: Mariners to win.

Prediction:

 

Seattle Mariners win both halves
