The San Diego Padres spent plenty of money this off-season in an attempt to bolster their offense, and so far it looks like money well spent. San Diego is third in the National League in scoring, thanks to the big bats of Justin Upton and Matt Kemp. They host the Oakland A's at PETCO tonight, and I think the total looks a little low considering both teams rank in the top 10 in the majors in runs scored, and each team turns to the back end of their rotation.

Here are my keys to the game:

1. Pitching - The Padres will send Tyson Ross to the mound, and he's coming off yet another unimpressive outing. Ross (3-6, 3.81 ERA) gave up three runs on nine hits over six frames in a loss at Atlanta. He hasn't been any better at home, in fact his ERA is higher at PETCO than it is on the road. The A's counter with Jesse Hahn, who was chased from his last start early, not before giving up four runs on seven hits.

2. Derek Norris - He arrived in San Diego via the trade that sent Hahn the other way, and he leads all National League catchers with 39 RBIs.

3. X-Factor - The Padres have seen the total go over at a rate of 7-2-1 in their last 10 home games.

Selection: This is a play on the Athletics@Padres to go OVER the total (10*)
