Finally Cubs baseball is back on Friday, and with the way the Cubs have been playing that is actually a good thing. The Cubs are red-hot, winning nine of their last fourteen games which has moved them out of last place in the Central Division. The Diamondbacks have taken a step back this season after being one of the surprise teams last year. Sub par years from Justin Upton and Ian Kennedy have contributed to that fall from the top of the West. Mediocre is a word that should be used in describing the D-Backs season to this point, they are 6th in runs scored, and 10th in ERA in the National League respectively. The Cubs still sit near the bottom of the league in both runs scored and ERA but this has been a different team since Anthony Rizzo got the call near the end of June. In order for the Cubs to be successful this weekend they are going to have to get a lead early against the D-Backs starters as they rank near the bottom of the NL, 14th to be exact, in starter ERA with a 4.26. While the pen for Arizona is 6th best in the National League, full preview/breakdown after the jump.
