From Stark's piece on the Braves
How can we put this into a context that will drive home how astounding it is for any group to slug .500 as a team over a six-month season? What about this: 15 of the 30 teams don’t even have a single qualifying player who is slugging .500 this year, and that group includes the Blue Jays, Yankees, Phillies, Brewers, Giants, Padres and Reds.
But the Braves are almost certainly going to slug .500 — because their slugging percentage has actually been going up all season. It was .448 after April, .458 after May, .493 at the end of June and didn’t top .500 until Aug. 12. So if you toss out the first two months, they’re slugging .526.
Does a .526 slug seem good? It ought to … since it’s essentially the same as Mike Schmidt’s career slugging percentage. Yep, it doesn’t sound real, all right.
