Interfence with Umpire

[BSUmp16]

Maybe this has been discussed before, but it seems to happen every so often:

Play is being made at the plate or it's a long fly ball down the left field line which could be fair or foul by inches. Umpire lines up TBX ready to make the close call right where he wants to be, when the batter or preceding runner gets in the way of making the call (example: ump's moving to his right to follow the throw and LHB's standing there, or the RHB leans over the baseline just as the balls about to land near the left field line partially blocking the view, or some other such).

No obstruction and no interference of the play itself, just interfering with the umpire's view, which makes getting the call right just a whole lot harder.

I'm assuming there's nothing that can be done other than telling the view-obstructing/blocking player not to do that again (and maybe explaining to the HC why you weren't able to get a good look at the play or ball).
