St. Louis second baseman Kolten Wong slugged a walk-off home run to give the Cardinals a 5-4 victory over the San Francisco Giants and even their National League Championship Series at one game each.

The Giants had tied the score at 4-4 in the top of the ninth on a wild pitch by St. Louis reliever Trevor Rosenthal but Wong's lead-off blast to right field off Sergio Romo in the bottom of the inning won the game and sends the series to California for Game Three on Tuesday all square.

"I knew I hit the ball hard, but I also hit it low and I didn't know if it was going out or not," Wong told reporters.

St. Louis struggled for home runs in the regular season - only twice in 162 games scoring three or more homers - but got four of their five runs from homers on Sunday thanks to solo shots from Matt Carpenter, Oscar Taveras, Matt Adams and Wong.

The Giants did not have a home run on Tuesday, though they out hit the Cardinals 10-8 overall.
