The Story

The Seattle Mariners shut out the Oakland Athletics 5-0 at Oakland Coliseum on September 18, 2023, holding the home side scoreless through all nine innings. The DiamondIQ model's estimate opened with Oakland at a 30 percent chance of winning and closed at zero, a collapse driven largely by a handful of pivotal moments in the middle innings that erased whatever early footing the Athletics might have had.

The decisive swing came in the top of the fourth, when José Caballero launched a home run off JP Sears that shifted win probability by plus 17.7 percent in Seattle's favor, the single largest play of the game. Sears continued to struggle in the sixth, surrendering a Luis Torrens double that added another 7.1 percent to the Mariners' advantage. On the other side of the ledger, Zack Gelof twice grounded into double plays, costing Oakland 6.1 percent in the fifth and another 5.6 percent in the eighth, compounding the Athletics' difficulty generating any sustained threat against Seattle's pitching staff.

Caballero led all position players with a WPA of plus 17.3 percent and a RE24 of plus 1.6, while J.P. Crawford contributed plus 5.0 percent WPA at the same RE24 mark, and Torrens added plus 4.2 percent. On the mound, Bryan Woo was the model's top-rated pitcher at plus 14.0 percent WPA, supported by Tayler Saucedo at plus 4.1 percent and Justin Topa at plus 3.6 percent. Seattle finished with nine hits and zero errors against Oakland's five hits, producing a clean and commanding road victory.
