On September 12, 1942, a second inning two run shot off the bat of Whitey Kurowski, and a five hit, five strikeout performance by Max Lanier led the Cardinals to a 2-1 victory over the Dodgers at Ebbets Field in Brooklyn. This was a very important game for the '42 club. On August 5th of that season they were down by 10 games, and it looked like those Bums from Brooklyn would lay claim to their second consecutive National League crown. However, the National League team that called St. Louis home came storming down the stretch, and made up ground at a breakneck pace.
The Cardinals took the lead in the National League the next day with a doubleheader split, and there was no looking back, as the Dodgers had gotten stuck in the midst of a five game losing streak. That was Brooklyn's longest losing streak of the season, and the Cardinals made the most of it. The Dodgers did right the ship, as they went 10-2 in their last 12, with eight of those games coming in a row to finish off the season. However, the Cardinals went 11-1 during that same stretch of ball, and clinched the pennant with a doubleheader sweep of the of the Cubs on the 27th of September. Eight days after that pennant clinching sweep the Cardinals were World Champions.
