Todd Frazier was mic'd up during an at-bat in the Pirates Spring Training game today, and it is one of the cooler things I've seen in awhile.
The MLB, and other leagues, have been experimenting with ways to liven the game up for viewers in recent years. The MLB recently started having outfielders like Bryce Harper and others mic'd up in the outfield during actual regular season games which was a bit interesting. Outfielders can go long stretches without seeing any action, so it's may not be too distracting for them to be mic'd. This is a whole different ball game though. I doubt this gets carried over into the regular season, but it would be absolutely awesome if it did. Imagine having someone like Aaron Judge or Tatis mic'd up as they rip a ball into outer space. It would be interesting to hear the batters call out what pitch they expect to see next as they step into the box. Like I said I doubt this happens, at least this year, but it could be something to watch out for in the future. Build a camera into their helmet as well so we can get a 1st person view from the box as well. The catchers or umps should have cameras on theirs by now anyway.
