Seattle Mariners at Pittsburgh Pirates: Final Score & Recap

The Seattle Mariners rolled to a 10-3 victory over the Pittsburgh Pirates at PNC Park on August 18, 2024, sending the DiamondIQ model's estimate of a Pittsburgh win from 50 percent before first pitch all the way to zero by the final out. Seattle built its lead methodically, scoring in five of the nine innings while holding the Pirates to just five hits and forcing two Pittsburgh errors. The Mariners' 13-hit attack and clean defensive performance left little doubt about the outcome as the game progressed.

The decisive turns in win probability came early and reinforced Seattle's control throughout. In the bottom of the first, George Kirby erased an Oneil Cruz plate appearance with a strikeout that swung win probability 5.0 percent in Seattle's favor before the Pirates could threaten. The top of the second inning proved particularly damaging for Pittsburgh, as Luke Raley's strikeout against Jake Woodford — a sequence that shifted win probability 7.6 percent toward Seattle — was preceded by Victor Robles delivering a double worth 4.2 percent. The four-run fourth inning, capped by a Josh Rojas home run off Woodford that added another 5.0 percent swing, essentially closed the door on any Pittsburgh comeback. Bryan De La Cruz's groundout in the bottom of the second, a 9.4 percent negative swing for Pittsburgh, underscored how thoroughly Kirby neutralized scoring opportunities.

George Kirby was the central figure on the mound, producing a game-high 22.7 percent in win probability added and holding Pittsburgh's lineup in check across his outing. Among the Seattle hitters, Luke Raley led with 8.3 percent WPA and a 0.9 RE24, while Josh Rojas contributed 6.4 percent WPA and a 1.2 RE24 anchored by his home run. Victor Robles rounded out the top performers with 5.3 percent WPA and a team-best 1.3 RE24, making the top of the Seattle order a consistent problem for Pittsburgh pitching from the opening frame onward.
