The most experienced level of Cal Ripken Baseball, Cal Ripken Majors is recommended for 11 and 12 year old players.

Cal Ripken Baseball is played under the Official Baseball Rules, but implements some special rules as necessary for the development and welfare of this young age group.

The game is played on a 70-foot diamond with a pitching distance of 50 feet. In order to encourage the league to train more pitchers, there are rules that set the maximum number of innings a pitcher may pitch in a calendar week.

Regulation games consist of six innings or four innings if a game is called.
