That said, I think either the Dodgers or Giants will get hot after the All Star break and run away with this division.
Look for the Dodgers to be big time spenders over the next month or so... Not so sure about the Giants, however I am 100% sure that LA will be very aggressive leading up to the trade deadline.
As for the Dbacks, there are rumors floating around about guys like Joba Chamberlain and Gallardo from the Brewers... As always it will come down to what they have to cough up in return... Names like Archie Bradley, Skaggs and Miley have been circulating.... I can't see them letting Bradley go, however, an argument can be made for a deal that would include Miley...
Still, the Dbacks need so much more than guys like Chamberlain and Gallardo offer... I honestly don't believe they can make enough moves this season that would make much, if any sort of difference at all... We won't win our division no matter what and therefore, the post season is out as any team from the West will need to win the division to get into the playoffs...
