While I do not support the behavior of Crawford or Maddon here--arguing balls and strikes is strictly forbidden--the conduct of home plate umpire Bob Davidson was particularly egregious. Watch and listen here (h/t IIATMS).
Moreover, the Rays have a good case. Davidson's strike zone is one of the most inconsistent I've seen in some time. See below:
The diagram above, from Brooks Baseball's PitchFX Tool, depicts balls (green) and called strikes (red) for both teams in relation to the strike zone (normalized for each batter). Note that Davidson was calling strikes nearly 18" out of the zone, while he called one ball nearly dead-center (and a few others well inside the zone).
While players and managers need to keep their opinions in check during play, umpires must also bridle their emotions--and do their job better. If human beings like Davidson can't call a consistent, let alone accurate, zone, then it's time to let technology take some of the load off their backs.
