Published bat pattern (13U–14U Interlock rules)

Recent DFW Interlock 13U/14U rules state bats must be labeled with either the USSSA 1.15 BPF stamp or the USA Baseball stamp (NCS-style dual acceptance). BBCOR (−3) and wood are allowed. For 14U, the maximum length/weight differential is −5.

Parent checklist

Interlock ≠ every DFW select tournament (PG / Triple Crown / NCS weekends have their own tabs).
Guest-player rules are strict — equipment still follows Interlock when you play in it.
At 14U, a −8 USSSA bat that worked at 12U may be illegal under the −5 cap.

Confirm with your association: Interlock is shared across home orgs. Your town packet + the Interlock PDF both matter.
