This is probably the biggest series of the year for the Arizona Diamondbacks and San Francisco Giants. A series win for Arizona probably wraps up the division with four weeks to play, a series loss makes things even more interesting.
The DBacks will face a tough pitcher on the mound in the series opener. Matt Cain is 10-9 with a 2.87 ERA, though he typically receives little or no run support. As for Joe Saunders, the lefty will face what is probably San Francisco's best lineup at the moment.
First pitch is scheduled for 7:15.
