Sporting News: MLB umpires missed 34,294 ball/strike calls in 2018, study shows.
This equals 14 per game on average. Which means some games maybe miss just a few, and some games are completely screwed.
55 games ended on incorrect calls last year.
Wouldn't you know it, the culprits are the old arrogant umps who DGAF. The better ones are the younger guys. But this info doesn't determine World Series crews, as the DGAF crew gets the biggest stage.
Study also finds a two-strike bias, and blind spots in the strike zone.
