CINCINNATI (AP) - Not just any comeback would get San Francisco back to playing for a pennant. It would take one of Giant proportions.
And Buster Posey believed it could happen. Even after the Giants left the West Coast down two games, the National League batting champion insisted his team could pull it off, despite the long odds.
With one swing, he got everyone else believing it, too.
The San Francisco Giants celebrate after defeating the Cincinnati Reds to win the National League division series.
Posey hit the third grand slam in Giants' postseason history on Thursday, and San Francisco pulled off an unprecedented revival, moving into the championship series with a 6-4 victory over the Cincinnati Reds.
"You don't want to be in a lose-and-you're-out scenario," reliever Jeremy Affeldt said, wearing a brace on his left wrist so he didn't hurt it in the champagne-flavored clubhouse celebration. "We've been in that situation for three days. We're probably going to sleep well tonight."
They'll play either Washington or St. Louis for the NL pennant, Sunday, not caring at all who they face.
"We could go up against anybody at any time," shortstop Brandon Crawford said. "Being down 2-0 and coming back and winning three at their place, it's an unbelievable feeling."
Game 1 of the NL championship series will be Sunday, either in Washington against the Nationals or in San Francisco vs. the Cardinals. In the meantime, the Giants will stay in Cincinnati until their next opponent is determined tonight when the Cards and Nats play Game 5.
The Giants became the first NL team to overcome a 2-0 deficit in the division series, which began in 1995. Major League Baseball's changed playoff format this season allowed them to become the first to take a best-of-five by winning the last three on the road.
Nationals 2, Cardinals 1
WASHINGTON (AP) - The Washington Nationals signed Jayson Werth to show them how to win. His game-ending homer extended their surprising season.
Werth led off the bottom of the ninth inning by driving Lance Lynn's 13th pitch into the left-field stands to give the Nationals a victory against the defending World Series champion St. Louis Cardinals and force a Game 5 in their NL division series.
As he circled the bases, Werth raised his right index finger in a "No. 1" gesture, while the announced crowd of 44,392 roared with delight.
The best-of-five series will end Friday night in Washington, with the winner advancing to face the San Francisco Giants in the NL championship series.
