Los Angeles Dodgers at Seattle Mariners: Final Score & Recap

The Los Angeles Dodgers defeated the Seattle Mariners 6-3 at T-Mobile Park on September 15, 2023, handing the home side a loss despite the DiamondIQ model entering the game giving Seattle a 48% chance to win. The Mariners carried a 1-0 lead into the fifth inning, but Miguel Rojas erased it in a single swing, launching a home run off George Kirby that shifted win probability by 23.7 percentage points — the single most consequential play of the night. An inning later, Max Muncy extended the Dodgers' advantage with a triple off Kirby that moved the needle another 16.9 points, pushing Los Angeles into a commanding position. Seattle briefly threatened in the bottom of the sixth when Teoscar Hernández singled off Bobby Miller to close the gap and produce a 16.3-point swing back in the Mariners' favor, keeping the game from getting away entirely.

Los Angeles answered by methodically sealing the outcome. J.D. Martinez's single off Matt Brash in the top of the eighth added another 14.1 points of win probability for the Dodgers, and Seattle's Mike Ford compounded the Mariners' misfortune by striking out against Ryan Brasier in the bottom half, a sequence that cost Seattle 12.3 points of win probability and effectively ended any realistic path to a comeback. By game's end, the DiamondIQ model placed Seattle's win probability at 0%. Rojas led all position players with a WPA of plus 19.4 and an RE24 of plus 1.8, while Martinez contributed plus 15.7 WPA. On the mound, Brasier paced the pitching staff at plus 13.3 WPA, followed closely by Brusdar Graterol at plus 12.8, as the Dodgers bullpen preserved the three-run final margin. Los Angeles finished with eight hits and committed no errors against Seattle's eleven hits and one error.
