What happened: A resurfaced post recalls Yordan Alvarez's walk-off home run in Game 1 of the ALDS, hit during Houston's run to the World Series four years ago. The clip circulated as the Astros prepare for another postseason push.

Why it matters: The throwback lands as Houston sits in the middle of a current series against Seattle, tied 1-1 heading into Sunday's game. Alvarez remains the Astros' top offensive threat, giving the old highlight renewed relevance.

What to watch: Astros and Mariners meet again with the series knotted 1-1 and the game still scheduled at 0-0.
