The Seattle Mariners defeated the Houston Astros 9-6 at T-Mobile Park on April 10, 2026, in a game that was never fully in doubt once Seattle seized control in the middle innings. The DiamondIQ model entered the night giving Seattle a 54 percent home win probability, and that estimate climbed steadily toward certainty as the Mariners answered Houston's early burst with sustained offensive production, finishing at 100 percent by game's end.
Houston struck first and loudly, plating three runs in the top of the second inning on a Christian Vázquez double off Emerson Hancock that swung win probability 11.2 percent in the Astros' favor. But Seattle responded by neutralizing that threat at every turn. Hancock bounced back to retire Vázquez on a strikeout double play in the fifth, a swing of minus 9.5 percent in win probability against Houston, and the Mariners then delivered their decisive blow in the bottom half of that same inning. Randy Arozarena launched a home run off Ryan Weiss that shifted win probability 18.6 percent toward Seattle, effectively turning the game. The Mariners added four more runs in the seventh to put the contest out of reach, and though Yordan Alvarez hit a home run off Cole Wilcox in the eighth for a 6.4 percent swing, it amounted to little more than cosmetic damage in a 9-6 final.
Arozarena led all players by WPA, finishing at plus 21.6 percent with a RE24 of plus 2.4, while Alvarez paced Houston despite the loss at plus 15.6 percent and a RE24 of plus 3.0. Leo Rivas also contributed positively for Seattle at plus 11.4 percent WPA. On the pitching side, Eduard Bazardo led the Mariners staff at plus 7.2 percent WPA, with Emerson Hancock and Gabe Speier each contributing above plus 6 percent. The Walker groundout into a double play in the sixth, worth minus 12.4 percent in win probability, proved symptomatic of Houston's inability to sustain pressure against a Seattle pitching staff that kept the Astros' lineup quiet when it mattered most.
