What do we have?

Either umpire CAN call obstuction, when they see it. That said, if my partner is right there on the play and makes no call, I'm not calling it - he has distance and angle and if he's not calling it I'm assuming he is seeing something that I could not see.

If I notice that partner is, for whatever reason, looking away from this fielder when it happens, I'm calling it.

More likely it is the opposite, you are seeing something your partner is not. After all, you had to see something that made you call OBS or the thought wouldn't have crossed your mind.
