Player Age Tables and Field Sizes

National Babe Ruth, which includes the Cal Ripken Division, calculates player ages ("Age Groupings") using a May 1 date cutoff.   The size of the field used for our games depends on the age of the player, so we explain that here as well. 


Various youth baseball organizations group their ages differently.  Little League uses September 1 for its Age Groupings while National Babe Ruth/Cal Ripken uses May 1 for its Age Groupings.  This difference in Age Groupings means that players born between May 1 and September 1 will be considered different ages for Cal Ripken versus Little League. 

By offering programs for players from age 8 through age 18, Stamford Babe Ruth can seamlessly accommodate players as they age, and can place players on the teams/age groups and field sizes that best fit their development.

No player under the age of 20 is barred from, or forced to leave, Stamford Babe Ruth because of their age.

The chart below shows the FALL 2023 / SPRING and SUMMER 2024 Babe Ruth Age Groupings for all ages that our programs cover:

Unlike Little League , which requires all players under 13 to play on a 46/60 infield (i.e., 46 feet from pitchers mount to plate, and 60 feet between bases) until they graduate to a full -size 60/90 infield, Babe Ruth's Cal Ripken division allows players to graduate to an intermediate sized 50/70 infield as they mature. The 50/70 option benefits two groups of players:  

  • 11 and 12 year old players who physically mature earlier than their peers , and can graduate to a larger field than the small 46/60 field that Little League requires that age group to stay on;
  • 12 and 13 year old players  who physically mature later than their peers, and whose development is better served by a gradual transition to the regulation 60/90 field 

For our programs, Ripken players between 8 and 11 years old will generally use the same 46/60 infield size that they are accustomed to in Little League. Players between the ages of 11 and 13 may play some or all of their games on a 50/70 infield depending on our determination of each team's relative developmental level and skill set.  Players over 13 play all games on a 60/90 infield.
