Astros celebrate Yordan Alvarez' walk off home run.
Astros fans should never leave Minute Maid Park until the final out. Yordan Alvarez launched a massive walk off home run with only one out remaining to take Game 1 in the American League Division Series against the Seattle Mariners. Fans that came early took part in the pregame Street Fest held outside the stadium. (Photos by Jack Gorman)
