Yordan Alvarez authored the rarest first inning in MLB history Friday night. Alvarez homered twice before the Houston Astros recorded a single out. The Astros then beat the Kansas City Royals 10-8 in the series opener.

Alvarez Slams and Multi-Homers in the Same Frame

Alvarez opened the first inning with a two-run homer to the opposite field. Alvarez later cleared the bases with a two-out grand slam to center field. Those two swings handed Yordan Alvarez six RBIs in one inning. Houston scored nine runs in the first inning against Kansas City.

Neither starting pitcher escaped the opening inning at Kansas City on Friday. The Royals answered with five runs in the bottom of the first to trail 9-5. Both bullpens then held the score steady from the second through the seventh inning. Kansas City stayed within striking distance behind that early five-run response.

Alvarez became the first MLB player to hit a grand slam and multi-run homer in one first inning. Alvarez also tied Philadelphia slugger Kyle Schwarber for the MLB lead with 24 home runs in 2026. Schwarber leads the National League in home runs for Philadelphia this season. Alvarez now matches that 24-homer total across both leagues.

Alvarez became the 63rd player in MLB history to homer twice in one inning. Alvarez is the first Houston player to do so since Jeff Bagwell on June 24, 1994. Alvarez also joined a group of eight players with a grand slam and multi-run homer in an inning. Kendrys Morales produced the previous such inning for the Angels in 2012.

Houston led 9-0 before Kansas City came to bat in the first inning. The Astros held on for a 10-8 win after Kansas City rallied within 9-8 in the eighth. Houston added a ninth-inning home run to restore the two-run final margin. Alvarez drove in six of the Astros’ ten runs by himself.

Alvarez produced the grand slam and the two-run homer before any out registered. The feat stands alone across more than a century of MLB box scores. Houston needed every run from Alvarez as Kansas City pushed within 9-8. The Astros leaned on Alvarez to survive the back-and-forth opener in Kansas City.

Alvarez carries a share of the MLB home run lead through the 2026 season. The Astros chase American League West position behind Alvarez and his 24 homers. Houston and Kansas City continue their weekend series after the 10-8 opener. Alvarez aims to push his home run total clear of Schwarber.
