Change the call?

[Mark Dexter]

I know the philosophy many of you guys have is that if a partner comes over to "ask" you about a call, he must have enough info, so you change it. What about this situation?

A1 is holding the ball right outside the post by the endline in their frontcourt. B1 comes in, slaps the ball, ball clearly hits off of A1 and OOB. I whistle - call out B's color.

My partner (at trail) shouts that it's A's ball as it tipped off of B. He then comes over and tells me as such. I reply that I clearly saw the "slap" by B then the touching by A, shouted out B's color, pointed, and put the ball into play.

Do you change this when he comes in or not? (Unfortunately running clock, so no discussion or postgame.)
