Fear of actually being hit by a pitched ball is diminished. It makes the game safer and improves the playing confidence and ability of all participants.
Minor (ages 9-10)
Recommended for ballplayers ages 9-10. Players build and refine their fundamental skills while beginning to understand game strategy and teamwork. In most regions, participants first experience post-season tournament competition in this level, leading to the 10 Year-Old World Series.
Major (ages 11-12)
The most experienced level of Cal Ripken Baseball, 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. Under the Major Division, there are two formats, the Major/70 and Major/60
divisions. In both formats, games consist of six innings. 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 calender week.
