Well.
If the Cubs are going to make any sort of run at the third wild-card spot (all the other NL postseason spots are basically out of reach at this point), now is the time.
The Cubs’ next 12 games are against teams who have losing records, worse than the Cubs. They begin with the Marlins, who had a fire sale this summer and are 14-23 since they took two of three from the White Sox in early July. (The Cubs are 21-16 over the same time span.)
For more on the Marlins, here’s Ely Sussman of the Marlins site Fish on First.
