Beginning with Championship play in 2014 (Championship play includes all NIT’s, State, Regional, World and Super World Series tournaments) the .52 c.o.r. 275lb compression ball will be mandatory. Beginning 1/1/15 the .52 c.o.r. 275lb compression softball will be mandatory for all NSA Play. NSA recommends that all Silver and Bronze play use the .52 c.o.r. 275lb compression ball beginning 1/1/2013

In 2011 the NSA announced a new 2012 bat standard and bat logo for its bats.  Beginning 1/1/15 all bats used for NSA play will have to bear the NSA 2012 logo.  See Rule 3 of the official NSA Rule Book for the logo.  No bats will be grandfathered in that DO NOT bear that logo, No exceptions.  NSA feels that this 4 year process has been fair and ample time to get plenty of use out of the bats not bearing the logo.


Multi Layered Softballs will be BANNED effective June 1, 2012.
