You should probably brace yourself for an unhappy stretch of baseball. After the Cubs host the Rockies, they head out to Arizona to take on the Diamondbacks, and then they get the Dodgers-Reds-Cardinals-Giants-Reds-Marlins-Red Sox. That, my friends, is a brutal stretch. In particular, the two Reds series and the Cards series will be put up or shut up time for the Cubs.
