How many games are in the alds?

Answer 1

The ALDS stands for 'American League Division Series', which is the third highest championship. (Right behind the ALCS and World Series)

It is a best-out-of-five series, meaning the first one to reach three wins, moves on.

Answer 2

Both the ALCS and the NLCS is the best-of-seven. Whichever team wins four games is the series champion. The winners move on to the World Series.
