The Tigers have all of six regular season games left to keep themselves from making the worst kind of baseball history. With their loss to the Braves on Sunday, they're one loss (and one Guardians win) away from blowing what was a 15.5-game lead over Cleveland on July 8 and a 14-game lead over the then-second place Royals and Twins. If the Tigers miss the postseason, those 15.5 games will be the biggest lead any first place AL or NL team has ever given up in 125 years of modern era baseball.
Detroit's collapse has been stunning, and it's an incredible indictment upon the front office's wheelings and dealings (or perhaps lack thereof) both in the offseason and at the trade deadline.
