The Seattle Mariners return to T-Mobile Park for Wednesday’s series finale against the Baltimore Orioles with a 31–29 record and a growing sense of momentum after finding their rhythm on both sides of the ball in recent weeks, despite an uneven 3–7 ATS mark in their last ten home games. While their spread record at home may raise eyebrows, it doesn’t reflect the broader success the Mariners have enjoyed lately, especially with a 9–1 ATS stretch overall that has helped push them back into the thick of the AL West race. Cal Raleigh has been the team’s most dangerous hitter, leading the charge with 15 home runs and timely production in the middle of the order, while Julio Rodríguez has come alive in recent series with a combination of multi-hit games, defensive highlights, and basepath aggressiveness that has set the tone atop the lineup. Seattle’s offensive approach has evolved from passive early-season inconsistency into a more aggressive, contact-first identity, aided by quality at-bats from Ty France, J.P. Crawford, and young contributors like Dominic Canzone, who have all stepped up during high-leverage moments. On the mound, the Mariners boast a 3.78 team ERA and have struck out 367 batters in just over 400 innings, with their rotation continuing to shine thanks to the efforts of Logan Gilbert and Bryce Miller—both of whom have turned in quality starts in their recent outings.

The key question remains the bullpen, which has been erratic at home and has allowed a few late-inning leads to slip, a major reason why the Mariners haven’t covered more consistently at T-Mobile Park. Still, the back-end options, including Andrés Muñoz and Gabe Speier, have flashed elite stuff and are more than capable of shutting the door if deployed with proper matchup strategy. In this series finale, Seattle will need a strong outing from whichever starter gets the nod—possibly Bryan Woo or George Kirby—to avoid overextending their bullpen and to neutralize Baltimore’s veteran lineup that can capitalize on walks and missed locations. Defensively, the Mariners continue to excel with athleticism and sharp positioning, frequently turning in game-changing plays that swing momentum and protect slim leads. Manager Scott Servais has consistently emphasized fundamentals and tight in-game adjustments, which has helped Seattle weather their early struggles and stay within striking distance of the AL West lead. The Mariners know that holding serve at home in series like this is critical to building a playoff-caliber record, and Wednesday offers a clear opportunity to showcase their improved balance and finish off the Orioles with timely offense, solid pitching, and cleaner bullpen execution. A win here would not only lock down another series victory but also further reinforce that the Mariners, with their deep rotation, maturing lineup, and strategic discipline, are rounding into the postseason form many expected when the season began.
