Kolten Wong and the St. Louis Cardinals rallied again with their latest postseason power show, tying the NL Championship Series at a game apiece.

After the final party at home plate, reality set in: They might be without Yadier Molina the rest of the way.

Wong hit a leadoff home run in the bottom of the ninth inning and the resilient Cardinals beat the San Francisco Giants 5-4 Sunday night.

The Cardinals came back after losing Molina to a strained oblique muscle in the sixth. The All-Star catcher was getting further tests and Manager Mike Matheny said it “didn’t look real good.’’

“We’ll wait and see, and right now we’ll just go ahead and keep celebrating a very tough, hard-fought win. I am real proud at how these guys kept coming,’’ Matheny said.

The best-of-seven series resumes Tuesday night with Game 3 in San Francisco, with John Lackey going for St. Louis and Tim Hudson starting for the Giants.

In a back-and-forth game, St. Louis got homers from rookie pinch-hitter Oscar Taveras in the seventh and Matt Adams in the eighth to take a 4-3 lead.

After the Giants tied it on a wild pitch, Wong hit an 0-1 delivery from Sergio Romo for his second big home run this postseason. The rookie’s seventh-inning drive was the decisive blow in Game 3 of the NL Division Series against the Los Angeles Dodgers.

St. Louis, last in the NL with 105 home runs during the regular season, has hit 11 homers in six playoff games - seven in the seventh inning or later. Earlier, Matt Carpenter connected for the fourth time this postseason.

“We just knew we had to keep grinding,’’ Wong said. “When you lose someone like Yadi, it’s definitely tough for us, but we told ourselves we’ve been going through this all year. Grinding up and down, not getting any easy pass, so we’re all so confident.’’

It was a rare postseason failure for the reliable San Francisco bullpen, which allowed a home run in each of the final three innings.

“They are the reason we’re in this situation, and you give [the Cardinals] credit,’’ Manager Bruce Bochy said. “They threw out some good at-bats and we made a couple of mistakes and they took advantage of them.’’

The Giants made it 4-all when pinch-runner Matt Duffy dashed home from second base on a two-out wild pitch in the ninth. San Francisco wound up losing for just the second time in its last 14 postseason games.

Seth Maness retired Pablo Sandoval on a comebacker with the bases loaded to end the top of the ninth, and got the win.

Maness came on after closer Trevor Rosenthal couldn’t hold a one-run lead. Rosenthal’s pitch bounced off the glove off backup catcher Tony Cruz and Duffy, running on a full count, never broke stride and slid home with the tying run.

Molina bent over in pain after a swing and didn’t make it out of the batter’s box on a double-play ball in the sixth. Wincing, he gingerly walked off the field.

Adams, whose three-run shot off Clayton Kershaw put St. Louis in front for good in their clinching playoff win over Dodgers, homered off Giants reliever Hunter Strickland.

Gregor Blanco’s fourth postseason hit in 31 at-bats put the Giants up 3-2 in the seventh, but Taveras re-tied it in the bottom half with a homer off Jean Machi just inside the right-field foul pole.

Carpenter hit a solo home run off Jake Peavy in the third. Randal Grichuk singled with the bases loaded in the fourth to make it 2-0.
