Softball/ASA slowpitch rules


ASA softball COED teams
here is what I see in the rule book for slow-pitch softball.
pitcher should place his pivot foot on the plate for a complete 1 second and then deliver the pitch.
Pivot foot must remain in contact with the pitcher's plate until the release of the ball.  Pitcher can step to either side to deliver or step back as long as his pivot foot stays on the plate until the delivery or release from the hand.

can the pitcher take two steps going towards the pitching plate step onto the plate and finish walking through to complete a pitch?

asking our umpire to stop the opponents delivery in a game last night and he said it was legal.  Is he right or wrong?  

Thank You

Hi KB,

Some local orgs and state assoc are experimenting with some different pitching rules, such as MI using a pitching box up to 6' behind the pp.  However in strict ASA play a pitcher cannot "walk through" the pp.  The 1 sec is the pitcher must come to a full and complete stop w/ the ball in front of the body.

Unless you have some local rule this is an IP all the way.

I can answer all questions about book rules and "case book" rules governing the playing of ASA softball. Have a REAL situation that happened and are not sure the proper rule was applied, ask me.


I am a registered ASA umpire, a MASA "At-Large" umpire since 1996 and a retired District Umpire-In-Chief. I have very extensive experience in MASA State Championship and ASA national qualifying tournament play both as an umpire and an Umpire-In-Chief. I completed 3 ASA National Schools including the ASA national advanced umpire school in Ok City("Bernie" for those who know him was the lead clinician, I survived the week and couldn't let my kids watch the game tapes when I got home. No, I love you Bernie). I was one of 4 "Yankee" umpires selected to umpire the Men's D National East Championship in 2002 in Winter Haven FL
