They have 23 more games against teams that currently have a record above .500. 6 vs MIL, 6 vs AZ, 4 vs PHL, 4 VS LAD and 3 vs NYM. The rest is mainly against the rest of the NL Central. So 64 more games vs .500 or worse teams. If they can take 2 of 3 from all these games, that would be 43-21, leaving them at 79 wins. Have a couple hiccups here and there against those teams and hopefully they can go at least 38-26 (.590 W%). Then you have those 23 games against the good guys. 10-13 against those teams would leave the Cubs at 84 wins. If 5 or 6 of those 10 are against Milwaukee, maybe that's enough. If not, it's probably a bit short. I think the best hope is that Milwaukee goes on another cold stretch like they went through earlier this season.
