Cincinnati, OH (Sports Network) - Buster Posey's grand slam punctuated a six- run fifth inning, helping the San Francisco Giants claim a piece of history in a 6-4 decision over the Cincinnati Reds in the fifth and deciding game of a National League Division Series from Great American Ball Park.
Brandon Crawford picked up two hits, an RBI and a run scored for the Giants, the World Series winners of two seasons ago who became just the second National League club to win a first-round, best-of-five series after dropping the first two games.
Los Angeles initially accomplished the feat against Houston en route to a championship during the strike-shortened 1981 season.
Pablo Sandoval hit safely twice and scored, while Angel Pagan also drove in a run for San Francisco, which also became the first NL squad since the advent of the wild card era to win a division series after losing two in a row at home to start.
Matt Cain (1-1) lasted 5 2/3 innings, allowing six hits and three runs, while walking two and fanning five. Sergio Romo posted his first career postseason save by recording the final four outs.
The NL West champions now await the winner of Washington-St. Louis in the other NLDS matchup to compete for the pennant in a best-of-seven series.
