The Cubs clinch their 14th National League pennant when the team beats the second-place Cardinals in the first game of a doubleheader sweep at Sportsman's Park, 6-2. The victory marks Chicago’s 20th consecutive win, a streak extended to the National League record of 21 with a 5-3 triumph in the nightcap.
Replacing Johnny Mize, tossed by an ump for arguing, Cardinal rookie first baseman Walter Alston makes an error in handling two chances and strikes out in his only major league at-bat. However, 'Smokey' will win seven pennants and four World Series in his 23-year Hall of Fame career as Dodger manager from 1954 to 1976.
On the last day of the regular season, the Cardinals clinch the National League pennant as sore-armed hurler Ernie White throws a five-hit complete-game, beating the Cubs in the first game of a twin bill, 9-2. The Redbirds also win the nightcap to finish the season with 11 victories in their final 12 games.
In the season finale, Mark McGwire ends the historic season by hitting his 69th and 70th home runs in the Cardinals' 6-3 win over the Expos. Big Mac's #70, which he strokes his last at-bat off Expos' rookie Carl Pavano of Southington, Connecticut, also establishes a National League record for round-trippers hit at home with his 38th Busch Stadium blast.
