Endicott Teener League (ETL), with the support of our Sponsors, provides opportunity for teenagers in the Greater Endicott area to play baseball in an environment that is fun, instructional, and competitive. Practices and home games are played at Sertoma Field. Practice begins mid-April, weather permitting.

ETL participates in the Tri County Teener League (TCTL), along with the other teener baseball leagues in the tri-county area. TCTL offers 5 divisions of play: 14B, 14A, 16B, 16A and 19U. The baseball age 14 and 16 and Under divisions are subdivided into "B" for community teams and "A" for travel and school-ball players. The 19 and Under division is combined.

Each team plays a 12-game regular season versus the other teams in their division, with 6 home games and 6 away games. Regular season typically begins in early June. Single-elimination playoff culminates in championship games, typically played in late-July. TCTL follows the National Federation of State High School Associations (NFHS) baseball rules, except as otherwise specified in the TCTL by-laws.
