Yes. Each season teams will play 15 to 18 games against teams from the other league.
There are two leagues in American major league baseball, the American League and the National League. The American League has the designated hitter rule which allows for someone other than the pitcher to bat in the pitcher's place. The pitcher does not bat in the American League. The National League does not have the designated hitter rule. The pitcher does bat in the National League.
What is the reason the American League in Major League Baseball is referred to as the Junior Circuit?
Major League Baseball (MLB) teams are divided between National and American League. Within these leagues, teams are further divided into divisions: East, Central, and West; therefore, in total, there are six (6) divisions (or "conferences") in MLB, including National League East, National League Central, National League West, American League East, American League Central, and American League West teams.

The opposite is true for the American League.. if they are playing a National League team in their stadium (so the American League would be visitors) they are required to have their pitcher bat
