OBR 7.10 requires that "An appeal under this rule must be made before the next pitch, or any play or attempted play...If the defensive team on its first appeal errs, a request for a second appeal on the same runner at the same base shall not be allowed by the umpire..."

My question...what is considered an "error". Specifically, in a Pony 13-14 yo game, I had an appeal to 3B for R2 missing the base on a double. The throw in was from F8 to F6 at 2B. F2 called for F6 to throw to F5 at 3B saying they were appealing R2 missing the bag at 3B. F5 misplayed the throw which dribbled away. He picked it up and touched 3B. I did not allow the appeal since the first attempt was erred.

Did I make the right call?
