Let's put things in perspective:
The Giants got swept in Oakland last year -- a series in which they mustered one run1. Just an awful showing from that offense. That team went on to win a World Series.
So, maybe we should be content with four runs over two games in Oakland?2
1Against Trevor Cahill, Gio Gonzalez, and Ben Sheets
2Against Graham Godfrey and Guillermo Moscoso
