Sorry 92% is just not good enough in my opinion, and I think MLB agrees as this is a multi-billion dollar business where everything matters. This is especially true for the postseason.
I agree with this. But I also am flummoxed by MLB's failure to maximize the performance of its human umpires. The brutal funnel that all baseball parents know works endlessly to send only the very best of the best players to the top level of play, where they have to work tirelessly to stay there or they'll be discarded. If umpires were subjected to the same process on the way up, with constant training and correction once they get there, I think their accuracy would be very close to 100%.
