If you're going by the baseball reference "leverage" stat block, then yes. Hader has also been worse (over his career) in what baseball reference deems "high leverage", as has been almost any reliever. If there are men on base, you give up more runs than when men aren't on base. Relievers are also almost always pitching in later innings. Craig Kimbrel has a higher OPS against by almost a hundred points in "high leverage" than he does "medium leverage" situations. I don't think anyone would say that means he's not a great reliever. This is not to say that Jacob Barnes is some amazing find. But continuing to use this "leverage" index against Barnes is just an obscure usage. Barnes "late and close" index is relatively close to his career numbers. 2 out w/RISP he's actually better than his career numbers. There's a lot of numbers here that people can massage to make a case, but if you just continue to take one thing (high leverage) and say "he's not good at this"..... what's the context? 7th inning and later? Game within 2 runs? Who's definition of leverage? There's a lot of statistics out there that say he's been reasonably adequate in these situations over his career. If the Brewers wanna dump Barnes, I'm ok with that, but using the narrow definition of "High Leverage" to say he can't pitch certain innings is false, and there's data to back that up.
