2018 – The Orioles’ awful season continues as they blow an early 8 – 3 lead against Boston to lose, 19 – 12. This puts them 46 1/2 games back of the division-leading Red Sox, with 46 games remaining, meaning they are mathematically eliminated. It matches the earliest date this has happened in baseball history, set by the 1932 Red Sox and copied by the 1962 Mets, two notoriously awful teams, and the 46 games left to play at the time of elimination is a new record in the divisional era.
