Matt Holliday hit a two-run home run in the third inning, and Shane Robinson padded the lead with a solo blast in the seventh -- his first career postseason hit -- to push the Redbirds' series lead to three games to one.
Starting pitcher Lance Lynn delivered his best postseason start delivering 5 1/3 innings giving up two earned runs and striking out five batters. In his three previous starts in the playoffs, Lynn had allowed at least four runs in each game.
St. Louis lead off hitter Matt Carpenter has struggled throughout the series with just two hits against the Dodgers, but he delivered an extra-base hit to start the scoring in the third. With Daniel Descalso on second, Carpenter drove a RBI double into the gap in left center. Two batters later, Holliday drove him in on a 403-foot home run.
The Cardinals bullpen pitched 3 2/3 scoreless innings to finish the game for Lynn. Rookies Seth Maness and Carlos Martinez bridged the gap to closer Trevor Rosenthal in the ninth. Rosenthal picked up his second save of the NLCS.
Game five of the series is Wednesday at 3pm. A St. Louis win sends them to the World Series; a Los Angeles win sends the series to game six at Busch Stadium Friday.
