I'd be satisfied with a split in the D-Backs series but they really cannot afford to do much worse considering the Cards have a series with the Reds and the Brewers with the Bucs. 

A 1-3 series could possibly make the last WC spot all tied up with 3 teams. A 3-1 will more than likely keep their current lead, so this is the most important series of the year. The offense needs to continue to roll to do well.

Tonight will be a tough task against Grenke but we thought the same last week against Kershaw.
