The Twins are 9-1 over their last ten games. They're 19-11 against the AL East (thanks Baltimore) and now 2-2 against the Red Sox.
Berríos had an extra day off after an improved, but still okay, start. He lost his start against Boston in June, in the midst of regular bullpen implosions. That time was because the Twins forgot how to score for the series.
Let's guarantee at least a season split with another AL East team. Sure, they aren't going to make the postseason, but those are the teams you need to beat.
