Definitely generous, but looking at where the ball is caught can be a bit misleading with those sweeping sliders from lefties. If you pause when the ball just enters the frame at 0:01, it was probably only an inch or two off the black. Not a strike, but if the ump has been calling a wide zone and the pitcher is consistently hitting the target, it's one of those pitches that a pitcher will sometimes get. I think you have to look at this in the context of how an HPU has been calling the whole game.
Would I love a perfectly calibrated robo ump consistently calling the strike zone? Absolutely. Would I miss the "art" of catching if we go to robo umps? Definitely, but I think the improvement in accuracy / consistency for most games (e.g., with umps other than the top 2-3%) would still make it worthwhile. My sense during this CWS is that the umps have been doing a pretty damn good job, though.
