They have a 9 game west coast trip against 2 teams under 500 and the worse team record wise after this series, on paper they should win at least 6 of them.
Then in September, 25 games, outside of the 7 against the Reds and Mets, the others are all under 500 and basically the bottom of the NL record wise ahead of the Rockies, so none of them are sniffing a playoff shot.
So, conservative side no worse then 12-6 against the non playoff contenders.
So, even if they just go 4-3 against the Reds and Mets they should on the low side be able to win 20-22 games after this series for over 90 wins total IF they can just get back to playing good baseball again.
The schedule is way in their favor as far as teams they play after the Brewers, just need to start playing better baseball and start hitting better.
