Seattle Mariners at Kansas City Royals: Final Score & Recap

Kansas City rallied past Seattle 10-9 on June 7, 2024, at Kauffman Stadium in a game that swung dramatically after the Mariners had built a commanding early lead. Seattle erupted for seven runs in the first inning to seize control, and the DiamondIQ model's pre-game home win probability of 58 percent for the Royals had collapsed far below that figure by the time the early deficit materialized. Kansas City chipped away with four runs in the fourth and three more in the sixth to pull even, and the model's estimate steadily climbed back toward the Royals as the Mariners' bullpen faltered in the late innings.

The decisive sequence came in the bottom of the ninth against Seattle reliever Ryne Stanek. Bobby Witt Jr. delivered a triple that shifted win probability by plus 72.1 percent, the single largest swing of the game, vaulting Kansas City from a precarious position to the brink of a walkoff. Nelson Velazquez followed with a fielder's choice out that added another plus 15.9 percent to Kansas City's win probability and drove in the winning run, capping the comeback and pushing the model's estimate to 100 percent. On the other side, Hunter Renfroe twice hurt Kansas City's chances in quieter moments, grounding into a double play in the eighth for minus 14.4 percent and grounding out in the second for minus 13.9 percent, representing two of the three biggest negative WPA plays of the game.

Witt Jr. finished as the game's most impactful player with a cumulative WPA of plus 68.1 percent and an RE24 of plus 2.0, while Velazquez contributed plus 18.5 percent WPA and plus 1.1 RE24 in support. On the pitching side, Trent Thornton led Kansas City's staff with plus 13.5 percent WPA, followed closely by Collin Snider at plus 13.3 percent. Bryce Miller posted plus 10.2 percent WPA for Seattle in a losing effort, a reflection of his effective early work before the Royals' late surge rendered the Mariners' first-inning explosion insufficient.
