The Cleveland Guardians defeated the Tampa Bay Rays 3-1 at Progressive Field on April 29, 2026, a result the DiamondIQ model's estimate reflected clearly as win probability shifted from a pre-game 44 percent home-team figure all the way to 100 percent by the final out. Cleveland's offense did its most consequential work in the fifth inning, when Steven Kwan delivered a double off Drew Rasmussen that added 9.0 percent to Cleveland's win probability, followed immediately by a Chase DeLauter single off Rasmussen that pushed it another 7.6 percent. Those two hits proved to be the offensive spine of the game, as the Guardians scored two runs in the frame and never surrendered the lead.
Tampa Bay's best chance to claw back came in the seventh, when Jake Fraley reached on a fielders choice off Gavin Williams that technically added 11.4 percent to the Rays' win probability, and then again in the ninth when Yandy Díaz singled off Cade Smith for a 6.6 percent swing. Fraley, however, ended that ninth-inning threat himself by striking out against Smith, a play that cost Tampa Bay 5.8 percent win probability and effectively closed the door on any comeback. The Rays finished with six hits and an error, never managing to convert their late-game opportunities into the kind of crooked numbers necessary to overcome the deficit.
Gavin Williams was the story of the night from a pitching standpoint, accumulating a game-high 31.5 percent WPA across his outing and serving as the primary reason Cleveland's slim lead held through the middle innings. Cade Smith and Erik Sabrowski added 6.3 and 4.6 percent respectively in relief. On the offensive side, Kwan led all batters with a 12.3 percent WPA and a 1.0 RE24, while DeLauter posted 8.4 percent WPA and 0.9 RE24, and Brayan Rocchio contributed 7.4 percent WPA and a matching 1.0 RE24, giving Cleveland a balanced if modest offensive performance that proved just enough.
