Doubted and dismissed when baseball's postseason began, the Arizona Diamondbacks have spent October embodying the words of their manager, Torey Lovullo.

"Anything can happen," he likes to tell them.

What happened Tuesday night set up perhaps the most improbable World Series in baseball history: The Diamondbacks stunned the heavily favored Philadelphia Phillies with a 4-2 victory in Game 7 of the National League Championship Series. For the second consecutive night, they sauntered into Citizens Bank Park, a hellscape for visiting teams that had gone winless during the first six games here this postseason, and beat the Phillies twice.
