Champs’ season on line after topsy-turvy Game 4

The Astros faced incredible adversity but couldn’t quite overcome it all, and now their season is on the line. The Red Sox again showed the resiliency of a team that won 108 games in the regular season and pushed the defending World Series champions to the brink of elimination on Wednesday, beating the Astros for the third time in a row, 8-6, to take a 3-1 lead in the best-of-seven series.
