Play with Obstruction

[LIIRISHMAN]

I would wait as the PU to see if my partner was calling the obs.The fact that there was obstruction may not warrant you as the PU to make a call(depending on the call).A runner being called out and being obstructed warrants a reversal by the umpiring crew.It's ALL our jobs to make the game fair for both sides.Let's be honest we all have missed a call or play but not to allow your partner to call a outright obstruction call because you didn't see it is plain wrong in my opinion.
