Little League is getting younger.
The organization announced Thursday it is changing its age requirement, phasing out 13-year-olds from the league.
Little League is changing its "age determination date" to Aug. 31, which will prevent anyone who turns 13 during the baseball season from playing in the league, beginning in 2018.
The current birthdate cutoff of Apr. 30 will remain in effect in 2016 and 2017 for players born on or before Aug. 31, 2005.
Little League officials say the move will bring its registration in line with most school districts, allowing more kids to play with their classmates.
Many of the stars of the Little League World Series have been 13-year-olds, and dozens of teenagers played in the just completed tournament in South Williamsport, Pennsylvania.
