OK, so that call reversal at 2B that confused the entire booth.
Keith kept saying the the ball was 'dead' which was never the case. That it was often treated as if it were, the example of umps telling/signaling runners to slow down if/when they were running on ball four was mentioned, should have never happened and was part of the problem leading baseball into the age where the time between ABs and even pitches was treated as dead time even though it wasn't.
Yes, the runner 'is awarded' 2nd base due to ball four but if he chooses, by choice or via ignorance, to go in with a head-first dive he does so at his own risk and there's no reason why he shouldn't be subject to being put out if he comes off the base.
