I'd like to chalk this up to that....... is wasn't a save situation and he doesn't do well in those situations........
I'd chalk it up to rain, and he didn't have it tonight.......... but that is far and few between most night for the guy.
I think we could argue who would be better in the high pressure situations between Koji and Kimbrel............. but either is a good bet and Kimbrel has been pretty much lights out....
