I was convinced this was a non-issue and the right call was made until I saw this slo-mo. I still can't tell from this angle if the ball hits that bar but the thing that gives me pause is that the ball was caught in the palm of the glove. I have to question whether a ball caught in the palm of the glove would have enough force to cause the glove to strike the wall hard enough to make the sound we heard. If it were caught in the webbing, yes, but in the palm?....eehhh...
Let's be glad the Sox won or we'd be grousing about that catch for years.
