Pittsburgh Pirates at Seattle Mariners: Final Score & Recap

The Seattle Mariners shut out the Pittsburgh Pirates 5-0 on May 27, 2023, at T-Mobile Park, a result that moved the DiamondIQ model's estimate of a Seattle win from 55% before first pitch to a certainty of 100% by game's end. Pittsburgh managed just two hits against Seattle's pitching staff while committing two errors, and the Mariners compiled 11 hits to pull away comfortably against a Pirates club that never found its footing offensively.

The game turned decisively in the first two innings. Seattle struck immediately in the bottom of the first, with José Caballero's flyout representing a modest but meaningful early shift, and the Mariners blew the game open in the bottom of the second with a three-run frame that effectively ended any competitive tension. Eugenio Suárez's strikeout in that inning registered as the single largest win-probability swing of the game at plus 6.4 percent, a reflection of how emphatically Seattle's half-inning unfolded around it, while Julio Rodríguez added a double off Vince Velasquez that contributed another 4.9 percent swing in Seattle's favor. On the Pittsburgh side, Joshua Palacios's pop out off Luis Castillo in the top of the second carried a negative 7.6 percent swing, underscoring how thoroughly the Pirates squandered any chance of keeping pace early.

Luis Castillo was the dominant individual performer of the night, posting a WPA of plus 22.6 percent that dwarfed every other contributor and anchored Seattle's effort from the mound. Among position players, Suárez led all batters with a plus 9.7 percent WPA and a RE24 of plus 0.8, while Rodríguez posted a RE24 of plus 0.9 to complement his WPA of plus 3.2 percent. Pittsburgh's only late flicker came when Jack Suwinski singled off Gabe Speier in the seventh for a 3.3 percent swing, but with Seattle already leading 4-0 at that point, the moment carried no consequence.
