BaseRuns has merit. Over the course of a season, a team's luck is probably going to balance out and BaseRuns is representative of what *should* have happened, not what actually happened. Not unlike FIP or xFIP, really. The problem with these metrics is that a lucky team doesn't automatically become unlucky just so their FIP/xFIP/BaseRuns balance at the end of the season. The Twins were incredibly lucky in late April and all of May. That shot them out to a (going from memory) +8 BaseRuns record, which is insanely high. Well, guess what? Those lucky wins are in the bank. At that point, the BaseRuns record becomes kinda irrelevant because it doesn't factor in games that already happened and project from there. Right now, the Twins are +9 in BaseRuns. For all intents and purposes (again, going from memory here), they have been BaseRuns neutral for a month and a half. That means they're no longer lucky but because they banked so many wins early in the season, they're still within a few games of their high water mark of the season (which was +11 games over .500, IIRC). It's almost a given the Twins will have a ridiculously high BaseRuns differential for the entire 2015 season but that doesn't matter. They don't need to "keep beating the odds" because they beat the odds so soundly in May. They just need to stay luck neutral for the rest of the season and they're a playoff contender, BaseRuns be damned. Also, the luck neutral Twins of today are a better team than the lucky Twins of May. Sano, Hicks, Rosario, and Mauer are starting to produce while Kyle Gibson has mysteriously turned into a strikeout monster while inducing groundballs left and right. There's still some room for upward movement on this roster. To summarize a post that's about ten times longer than I originally anticipated, it's July and the Twins' BaseRuns record is pretty much irrelevant. I'd like to see a second version of the metric that projected the rest of the season and removed all that "this should/shouldn't have happened" garbage because that's water under the bridge. It happened. It can't be changed. My guess is that if BaseRuns took the Twins' 49 wins as fact and projected the rest of the season based on the last month of play (ie. using the current roster and not the one fielded in May), they'd put the Twins somewhere around 83-85 wins for the season (basically .500 ball from here on out).
