I will concede the point that if the Brewers continue to out BABIP the Cubs by 51 points, which they've done since the (very arbitrary!) May 22nd date you referenced, we'll probably be in trouble. Now, their BABIP over that stretch is higher than what any team has done in a full year this decade, so I'd say it's....somewhat unlikely. And the Cubs are 27th over that stretch, which implies some unluckiness in addition to the very good opposing pitching metrics referenced above. But hey, if that all continues for....reasons, yeah, they might win more games than us!
