Mariners Game #144 Preview and Discussion, 9/6/26: SEA vs. ATH

On September 6, 2026, the Seattle Mariners will face off against the Boston Red Sox in Game #144 at Fenway Park in Boston, Massachusetts. Starting pitcher Bryan Woo, who has a 22-12 record this season, is set to take the mound for the Mariners in what is expected to be a crucial matchup. The Mariners aim to avoid falling into the same humiliating home defeat that they suffered in August 2017, a streak they have managed to break since.

In honor of Michael Arroyo, the former third baseman known for his defensive prowess and clutch hitting, he will make his long-awaited debut in Seattle today. He will take the field at second base, providing Cole Young a rare day off. Jhonny Pereda will be behind the plate for Woo, while Cal Raleigh continues to lead the lineup at designated hitter, where his recent performance has been impressive following a three-hit night on Saturday.

For the Boston Red Sox, rookie left-handed pitcher Gage Jump will start the game for the Athletics. This will be Jump's first opportunity to face the Mariners since he made his Major League debut on May 26th, where he surrendered four runs over five innings. Jump will be eager to prevent a similar outcome this time around. The Mariners' lineup remains largely the same as in their previous game, with the exception of Carlos Cortes returning to left field and Brian Serven moving to the eighth spot.

Rookie Gage Jump's debut against the Mariners, following his first appearance on May 26th, has the potential to significantly impact the game's outcome.
