The 2004 St. Louis Cardinals were the only team to win 20 games in back to back months (July, August)
The 2011 St. Louis Cardinals, , 2006 Detroit Tigers, 2005 Houston Astros and 2000 New York Yankees were the only teams to go under .500 back to back months.
The 2006 St. Louis Cardinals, 2006 Detroit Tigers, and the 2000 New York Yankees were the only teams to go under .500 in September.
July (6) is the most common month for a team to win at least 10 more games then they lose. It has happened 5 times in September.
The 2006 Detroit Tigers (May, June), and the 2004 St. Louis Cardinals (July, August) are the only teams to go back to back months with at least 10 more wins than losses.
The 2003 New York Yankees are the only team to go 3 months in a single season, winning atleast 10 more games then they lost.
Moral of the story? Every month is just as important as the next. Games in April count just as much as games in September.
