Don't do this all the time. In fact, don't do this if you don't have to. Shucks, don't even do it.
At the risk of getting thoroughly lambasted, for which I'm ready, consider this . . .
Oftentimes the players themselves know who knocked the ball OOB. Just a brief pause to allow a slight, furtive glance at the players' reactions can give away what the correct call would be.
Note well: I'm not saying do this. But it seems to hold true the very few times I experimented with it. Or, I mean, I read about it somewhere. Or, I mean, BillyMac told me he did this all the time.
