Major League Baseball is reportedly in talks with umpires to mic crew chiefs so they can explain instant-replay decisions to fans.
Marlins relief pitcher Brad Ziegler said:
"It probably would be nice to get a little more explanation. They're supposed to say the call stands or the call's confirmed. 'The call stands' means you can't tell. A lot of times we don't get that ... they just signal out or safe. That's all we get on the field.
They may announce it on the PA, but it doesn't seem like that is consistent in all parks. And the acoustics in the stadium here — we have a hard time hearing what's on the PA in the bullpen"
