Mariners-White Sox Series: Raley’s Career Night Followed by Vargas’s Two-Homer Bounce (May 9-10, 2026)

Entering the weekend, the Chicago White Sox were on a three-game losing streak and held a 18-21 record. The Seattle Mariners had captured three of their last four contests, including a 12-8 win in the series opener. Both clubs sought to shift momentum—Chicago to halt its slide, Seattle to extend its surge.

Chicago’s win halted its three-game skid and moved the club to 18-21, a modest improvement after a 11-28 finish to the previous season. The offensive burst from Vargas and Montgomery provided a template for future run production. Seattle’s high-scoring opener kept the Mariners above .500 and highlighted Raley’s breakout potential, while the loss on May 10 underscored lingering inconsistencies in its starting rotation.

Reuters

• White Sox: Club officials praised the pitching staff’s ability to rebound from the previous day’s run-heavy loss, noting Kay’s five-inning performance and the bullpen’s four shutout innings as key to the victory.

Reuters

• Mariners: Seattle’s front office highlighted Raley’s career night as a catalyst for the win and commended Hancock’s composure despite early trouble, emphasizing the need for more consistent support from the rotation.

Seattle will start right-hander Logan Gilbert (2-3, 4.30 ERA) on Sunday, while Chicago will counter with left-hander Davis Martin (5-1, 1.64 ERA) in the series finale. Both teams aim to build on the contrasting outcomes of the May 9-10 games.
