Both National League divisional playoff series resumed on Thursday.
Buster Posey hit a grand-slam home run, part of a six-run fifth inning as the San Francisco Giants held off the Cincinnati Reds 6-4 to win game five of their divisional playoff series, enabling the guests to overcome a two-games-to-none deficit and win the series three games to two, becoming the first National League club to come back from two games down to win a divisional playoff series. The Giants will open the National League Championship Series this coming Sunday at home or at Washington, depending on who wins Friday's deciding game between St. Louis and Washington.
Jayson Werth hit a walk-off home run to leadoff the bottom of the ninth inning as the Washington Nationals squared their divisional playoff series at two games apiece with the St. Louis Cardinals with their game-four 2-1 victory at home. The fifth and deciding game of this series---and the San Francisco Giants' National League Championship Series opponent---will be decided at Nationals Park on Friday.
