The American League isn't providing much September drama, with the five playoff teams all but decided, but the National League might provide enough action for both circuits. Eight teams are battling for five spots and every day this week features at least one game between two contenders.
The two wild cards look like they probably will come down to teams in the Central or West, but there's still a race for the East division title.
Here's how the races stack up, with a look at the week ahead:
WHAT TO WATCH FOR
BIGGEST SERIES -- Dodgers vs. Cardinals: The Dodgers head to St. Louis for four games in a series with big implications on two divisions and the wild card. St. Louis swept three games at L.A. in August. Kenley Jansen gave up the winning runs in two of those three games, but he has pitched much better since then. The Cardinals have had some problems of their own in the late innings, but Carlos Martinez appears to have taken over closer duties, allowing just one run in 9⅓ innings since moving to the bullpen.
