With 9 games remaining, the Brewers playoff hopes are on life support. Factoring in the tie breaker disadvantage, they are 2.5 games behind the Phillies and 4 games behind the Padres. Fangraphs lists the Brewers playoff probability at 20.7% and 538 shows a slightly more encouraging 31%. The "elimination number" for the Phillies to close out the Brewers is 8; for the Padres the number is 6. In other words, if the Phillies win 8 of their last 10 (which is certainly possible given their schedule) and the Padres win 6 of their last 9, the Brewers can win out and still be out of the playoff picture.
If you're looking for something from the past to give you hope, I would point to the wild card chase in 2008. In early September the Brewers looked to be playoff bound with a 5 game lead over the Phillies for the wild card spot. But an early September slump, capped by a 4 game sweep by the Phillies, erased that lead. Now tied with the Phillies and 12 games remaining, the Brewers fired manager Ned Yost hoping a change would bring the team out of its funk.
Popular lore would have you believe that the change to Dale Sveum inspired the Brewers to a late season charge, but it didn't exactly work that way. The Brewers lost 4 of their first 5 with Sveum at the helm and, with only 7 games to play, found themselves 3 games behind the Phillies and 2.5 games behind the Mets, who were feeling the pressure after blowing a 7 game division lead with just 17 games to play the year before.
The rest is history. The Brewers won the final game of a series in Cincinnati, then came home to sweep 3 from the hapless Pirates, and 2 of 3 from the Cubs, who were coasting into the playoffs. The Mets made it all possible by losing 5 of their last 8.
Maybe 2022 will produce a similar improbable finish. All we can do is hope.
