Jayson Werth's solo home run in the ninth inning was the first walk-off homer in NLDS history that forced a Game 5.
Werth's home run marked just the fourth time in postseason history that walk-off homers have been hit on consecutive days. Raul Ibanez, Werth's former teammate with the Phillies, hit a walk-off homer in the Yankees' American League Division Series Game 3 win over the Orioles on Wednesday night. It also happened on consecutive days in 1995 and twice in 2004.
It was also just the third postseason walk-off home run allowed by the Cards in franchise history. The first was hit by Hall of Famer Mickey Mantle in Game 3 of the 1964 World Series, and the second by Jeff Kent in Game 5 of the 2004 NL Championship Series. That 2004 game was also the last time before Thursday that both teams managed three or fewer hits in a postseason game.
Jordan Zimmermann, Tyler Clippard and Drew Storen are just the second trio of relievers to each pitch at least one inning, allow no hits and strike out at least two batters in a non-extra-inning postseason game. The 2002 Braves (Kevin Gryboski, Damian Moss, Darren Holmes) also accomplished the feat in a loss in Game 1 of the NLDS against the Giants.
The Nats are the first team in postseason history to have two relievers (Zimmermann and Clippard) strike out the side in the only inning they pitched in the same game.
Washington won despite never having a runner reach second base.
Adam LaRoche's solo home run in the second inning marked the first postseason run scored by the home team in Washington since Oct. 7, 1933, at Griffith Stadium.
By allowing just one unearned run over six innings, Ross Detwiler lowered the postseason ERA of Nationals starters more than two points to 5.21. NL Cy Young Award candidate Gio Gonzalez, Zimmermann and Edwin Jackson combined to post a 7.62 ERA (11 earned runs over 13 innings) in the first three games. The rotation was a huge part of the Nats' success this season, posting an NL-best 3.40 ERA and accounting for a league-leading 72 wins.
Between his performance in the NL Wild Card game and Thursday's NLDS Game 4, the Cardinals' Kyle Lohse gave up just three earned runs on eight hits over 12 2/3 innings.
Zimmermann's seventh-inning appearance was the right-hander's first relief outing of his Major League career. Zimmermann, who's made 82 career starts, including in the Nationals' 12-4 loss in Game 2, struck out the side on only 12 pitches.
In his first postseason series, 19-year-old rookie Bryce Harper is just 1-for-18 with six strikeouts.
Detwiler continued to pitch well at Nationals Park, improving his 2012 home ERA to 2.43. His regular-season road ERA was 4.38 this season.
Both pitchers of record, Washington's Storen and St. Louis' Lance Lynn, were high school teammates at Brownsburg High School in Brownsburg, Ind.
