I like Arizona more then I like the Dodgers. Dodgers have been playing really well lately, winning 9 of 10 and 11 of 14. However, the 9 out of 10 has been against all clubs not in the playoffs as of today and only one of those teams, St. Louis, has an outside shot of getting in. 6 of the 9 have been against teams with a below .500 record. I know it isn't easy to win 9 of 10 but basically its been one bad team beating up on worse teams. I mean up until this Brewers series I thought the Cards had pretty much called it a season so I'm not sure I can even say the Dodgers beating them at the time was that impressive.
As far as the D'Backs/Giants game, for me it would more be a play against the Giants. They struggle to score runs, running out there Cain knows he can't give up more then three runs and that is tough for any pitcher. Could be a sucker play but I would rather take the hotter team and better offense against a team that can't score period. Last time the Giants scored more then 4 runs in a game they lost! Good luck with whatever you play.
