Arizona at San Francisco

The Giants have won 50 home games on the season, the most of any National League team. The Diamondbacks have now gone 6-18 on the road in their last 24 vs a team with a winning record. It will be hard for the D-Backs to change those losing ways with Kevin Mulvey on the mound. Mulvey has an 8.84 ERA and his three starts on the season about the same. The Giants starter, Brad Penny has some huge numbers vs the D-Backs as he is 8-3 for his career with a 2.13 ERA against them. The current D-Back roster has a combined .227 average against Penny with just one home run. Arizona also sports a 20-50 mark in their last 70 vs a team with a winning record on the season and have never gotten it done in San Francisco, where they are 21-44 in their last 65 played here. I'm going with the Giants in this one.
