Their odds of coming back are long; since the LCS expanded from five games to seven in 1985, only seven teams have rallied to advance to the World Series, including last year’s Giants. Only two others were even able to force a Game 7.
On the other hand, the Tigers need to beat the Red Sox on Wednesday night in Detroit in order to avoid falling into the same deep pit as the Dodgers currently find themselves.
But even with the homefield advantage, LCS history shows that just 26 out of 55 home teams have won Game 4 at home, a .473 winning percentage.
