Softball/moderate speed delivery


tks.. i pitch in senior 55+ softball league. rule says pitcher delivers the ball at moderate speed. they keep telling me to slow the ball down.      I have the legal arc from 45 feet.  can anyone define moderate  speed???

Hi Jack,

Sorry...."moderate" speed is solely in the judgment of the umpire, if it's more than 1 umpire calling it you are probably on the higher side of moderate and need to slow it down a bit.  I would have to see it, but what do other players and umps say?

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
