Giants-Cardinals, Game 2: Did you know?

Nobody expected this National League Championship Series to be easy for either team, right? The Cardinals blasted four home runs Sunday night en route to staving off a 2-0 NLCS deficit with a 5-4 victory in Game 2 at Busch Stadium. After the Giants tied the game in the top of the ninth, Kolten Wong hit a walk-off home run to send the series to San Francisco tied 1-1.

Here's what you should know from Game 2:

• Kolten Wong hit the fourth walk-off homer in Cardinals postseason history. The others: Ozzie Smith in the 1985 NLCS, Jim Edmonds in the 2004 NLCS and David Freese in the 2011 World Series.

• The Cardinals hit four home runs on Sunday night. They had just one four-homer game in the regular season (July 11 vs. Milwaukee).

• This was the Cardinals' fifth four-homer postseason game in franchise history. The others: 2012 NLDS Game 2 vs. the Nationals; 2011 WS Game 3 vs. the Rangers; NLCS Game 2 vs. the Astros; and 2004 NLDS Game 1 vs. the Dodgers.

• Fifteen of the Cardinals' last 16 runs have come on home runs. They have 11 this postseason after finishing last in the NL in homers during the regular season.

• The Cards became the first team ever to homer in the seventh, eighth and ninth innings of any postseason game.

• Wong is the fourth second baseman with a postseason walk-off home run. He joins Jeff Kent (2004), Alfonso Soriano (2001) and Bill Mazeroski (1960).

• According to ESPN Stats & Info, before Matt Adams, the only other Cardinals batter with two go-ahead homers in the seventh inning or later in the same postseason was Brian Jordan in 1996.

• Before his ninth-inning wild pitch allowed Matt Duffy to score the tying run from second base, Cards righty Trevor Rosenthal had thrown just one wild pitch all season.

• Rosenthal in the 2012-2013 postseasons: 20 1/3 innings, six hits, zero earned runs. Rosenthal this postseason: 3 2/3 innings, seven hits, two earned runs.

• According to the Fox Sports 1 broadcast, this was the second game in playoff history in which the tying run scored in the ninth inning on a wild pitch. The other? Game 6 of the 1986 World Series between the Red Sox and Mets.

• Joe Panik, who drew the game-tying walk, has walked twice in the postseason. Each came with two outs in the ninth and the Giants trailing by a run. Each led to the tying run.

• Oscar Taveras, who tied the game with a home run off Jean Machi in the seventh, also hit his first career homer against the Giants May 31.

• Taveras' seventh-inning home run was the first tying or go-ahead pinch-hit home run for the Cards in the postseason, according to ESPN Stats & Info. It was St. Louis' seventh postseason pinch-hit homer in club history.

• Yadier Molina, who singled in the second inning before exiting the game with a left oblique strain, now has more hits in the postseason (89) than any other player in Cardinals history.

• The Giants have allowed 14 runs this postseason -- eight on solo homers.

• Carpenter, who has four home runs in the postseason, had just eight home runs in 595 regular-season at-bats. It took him until June 28 (81 games) to hit his fourth regular-season home run.

• In 4 1/3 innings, Hunter Strickland has allowed four home runs this postseason. That's twice as many as Mariano Rivera allowed in his entire career.
