Astros starter Yordan Alvarez, who has posted a .397/.444/.569 line in his last 14 games after returning from injury, left today's game with a sprained ankle while running home. He was seen in a protective boot after the game and will be examined tomorrow. The Astros are only a half-game behind the first-place Mariners in the AL West, and have a three-game lead in the wild-card race, which is a crucial time.
