I really hope more is added to instant replay. If anyone watched the Little League World series, they got it right with the replay rules they set up. Each challenge took all of about 1-2min, and 6 of 13 challenges were overturned. To me that's crazy that almost 50% of questionable calls end up being wrong. If Little League can do this, why not MLB? I feel it doesn't make any difference that it was Little League either. Shitty calls happen at the MLB level all the time, and seems like more games are won/lost in question every year. A win with bullshit calls just doesn't feel like a win, and the same goes for a loss.
*LL Replay Rules: Each team gets one challenge each. If a call is challenged, and the umps were wrong, then that team gets to still challenge calls. However, if they are wrong with their challenge, then they lose challenging privileges for the rest of the game (but can reacquire ability to challenge calls in the case of extra innings).
