Texas Rangers at Seattle Mariners: Final Score & Recap

The Seattle Mariners defeated the Texas Rangers 1-0 on October 1, 2023, at T-Mobile Park, with the DiamondIQ model's estimate moving from a 53 percent pre-game home win probability to 100 percent by the final out. The game's lone run came in the bottom of the fourth inning, and Seattle's pitching staff was airtight the rest of the way, holding Texas to four hits across nine innings without an error.

The most consequential sequence came in the top of the ninth, where the Rangers mounted their best threat of the afternoon. Evan Carter's single off Isaiah Campbell represented the game's largest single win-probability swing, adding 10.6 percent to Texas's chances and briefly reopening the door. However, Marcus Semien's strikeout immediately swung the needle back by 10.1 percent, and Corey Seager's flyout cost the Rangers another 8.9 percent, effectively ending the threat. Campbell held firm to preserve the shutout. Earlier, in the bottom of the fourth, Ty France drew a walk off Dane Dunning that shifted the win probability by 8.5 percent, helping set the stage for what became the game's only run. Luis Torrens added a notable contribution in the bottom of the eighth, as his strikeout against Jonathan Hernández generated a 7.8 percent swing in Seattle's favor by keeping Texas's closer from inheriting a clean inning.

On the individual ledger, George Kirby led all pitchers with a 28.2 percent win-probability contribution, followed by Martín Pérez at 19.8 percent and Campbell at 15.2 percent. Among position players, Carter led by WPA at plus-9.5 percent despite appearing only late in the game, while France posted the strongest run-environment figure at plus-0.9 RE24, reflecting his situational impact in the fourth. Torrens checked in at plus-7.8 percent WPA despite a slightly negative RE24, underscoring how leverage shaped his contribution.
