Houston Astros at Kansas City Royals: Final Score & Recap

The Houston Astros held off the Kansas City Royals 8-7 at Kauffman Stadium on June 13, 2026, in a back-and-forth contest that saw the DiamondIQ model's estimate of a home win sit at 47 percent before first pitch and fall all the way to zero by the final out. Kansas City built momentum through the middle innings, most notably in the bottom of the sixth when Carter Jensen delivered a double off Enyel De Los Santos that swung win probability by 23.8 percent in the Royals' favor, briefly making Houston's grip on the game tenuous. The Royals had also received a boost from Brice Matthews, whose fifth-inning home run off Noah Cameron added 18.6 percent to Houston's win probability going the wrong way for the visitors, keeping Kansas City within striking distance through six innings.

Houston regained control in the top of the eighth when Jose Altuve launched a home run off Matt Strahm, the single biggest win-probability swing of the game at plus 26.2 percent, pushing the Astros back to the front. Yordan Alvarez then added a critical single off Alex Lange in the top of the ninth worth 18.0 percent, helping Houston extend its lead to what proved to be the decisive margin. Bobby Witt Jr. answered with a double off Bryan Abreu in the bottom of the ninth worth 17.0 percent, making things uncomfortable, but Kansas City could not complete the comeback.

Among the game's top performers by the DiamondIQ model's cumulative win-probability measure, Alvarez led all players at plus 24.0 percent WPA with an RE24 of plus 0.8, while Witt Jr. finished at plus 21.3 percent and Altuve at plus 20.6 percent despite being on opposing sides. On the pitching side, Bryan King paced Houston's relievers at plus 10.9 percent WPA, while Daniel Lynch IV contributed plus 7.2 percent for Kansas City. Houston's clean defensive effort, reflected in zero errors compared to one for the Royals, proved to be a quiet but meaningful factor in the Astros leaving Kansas City with the victory.
