Chicago White Sox at Seattle Mariners: Final Score & Recap

The Seattle Mariners defeated the Chicago White Sox 6-1 at T-Mobile Park on May 18, 2026, in a game that was never particularly close after the early innings. The DiamondIQ model opened with a 50-50 home win probability but closed at 100 percent in Seattle's favor, reflecting how thoroughly the Mariners controlled the contest. Seattle scattered its six runs across the third, sixth, and eighth innings while holding Chicago to a single run in the seventh, and the pitching staff surrendered just one error-free game on the defensive side.

The decisive swings came from both sides of the ledger. Randy Arozarena's double in the bottom of the third off Noah Schultz was the single largest positive play of the game, adding 9.1 percent to Seattle's win probability and serving as the early anchor of the Mariners' lead. Chicago's best chance at a rally materialized in the seventh when Tristan Peters hit a home run off Eduard Bazardo that added 7.9 percent win probability for the White Sox, briefly tightening things, but Randal Grichuk's flyout against José A. Ferrer moments later swung the probability back 6.5 percent the other way and effectively ended the threat. Colt Emerson then put the game away with a three-run eighth-inning home run off Trevor Richards, adding 7.8 percent, while Munetaka Murakami's single earlier in that frame off Ferrer had added another 7.1 percent for Chicago in what proved to be too little, too late.

Bryan Woo was the standout performer by the DiamondIQ model's accounting, finishing with a WPA of plus-30.5 percent, by far the largest contribution of any player in the game. Among position players, Arozarena led all batters at plus-11.9 percent WPA and plus-1.1 RE24, while Emerson posted a team-high RE24 of plus-1.8 to go with his plus-6.8 percent WPA. Ferrer added plus-14.6 percent WPA in relief for Seattle, reinforcing a bullpen performance that helped preserve a comfortable final margin.
