A .500 winning percentage. On its own, it's not a particularly special achievement. A team that goes .500 is, by definition, just average, equally as bad as they are good (and vice versa). Nobody throws a parade for a .500 record. A .500 record, except in rare circumstances, isn't getting you to the playoffs.
For the Orioles, though, .500 is a thrilling number. Reaching that .500 threshold would be a momentous achievement for a team that hasn't even sniffed being modestly decent in half a decade. The Orioles haven't finished a season at .500 or better since 2016.
