Unsustainably good things can happen for 140 games, even across a whole team. Two years ago there were lots of Cardinals fans trying to explain their RISP hitting by crediting the approach, but not so much when it regressed the next year. But yes, please tell Cubs fans more about how insecure they are in a game thread with a rival team on a Cubs website. I'm not sure the level of condescension he's been displaying is sustainable.
