The Prep League is made up of all 13 year old players. Since
Little League changed its cutoff date to September 1st, Babe Ruth
will accept those players with birthdates between May 1st and August
31st as “12 year-old swing players.”
This league is to help in the transition between the smaller Little
League fields with 60 foot base paths to the standard 90 foot base path of
traditional baseball while playing against players who are the same age. The prep league starts in the beginning of April and ends
the last week of June. Typically, the prep teams play 2 games per week.
The National League is for 14 and 15 year old players. The season starts in the beginning of April
and runs until the end of June. National league teams typically play 2 games
per week, depending on the season.
The Senior League is for players 16 and above. High school
sophomores who are 15 years old have the option to "play-up" in the Senior
League. Since a number of players in the senior league play high school sports,
the senior league season starts in mid-May. Seniors usually play 3 games per
week for 5 weeks.
