OTB Registration has been extended!
New players can sign up for $220. Returning players can sign up for $230 on a first-come, first-served basis.
As we approach our final deadline returning players risk losing their roster spots if they fail to register before all 240 positions are filled, which could happen without notice.
Please take note of our new aluminum bat changes for 2017:
Rule 6.4: Effective with the beginning of the 2017 season (overriding the rule created in 2005), all non-wood bats used during play must meet Batted Ball Coefficient of
Restitution (BBCOR) standard. All non-wood bats must be labeled with BBCOR certification, BESR labeled bats are considered illegal. Any batter using an illegal bat will be
ejected from the game. Any board-approved change in structure or differential will be made with the contingency that its implementation will be one (1) year from the date
of the board-approved change.
