How do I fix a ball that bruises underneath my fingernail on my middle finger and ring finger.  Bigger bruise on my middle than my ring.  Is the span to short? to long?  It only happens on balls that a certain driller drills, other ball is fine.  I know, don't take a ball back to that guy.  

How do I fix the ball though?

Thanks

My guess is too much forward pitch for your joint flexibility.  Is this driller copying an existing ball of yours?  If so, he's probably not checking the finger pitches.  --  JohnP
