The D-Backs decided to fill up all of their needs in the off-season. They wanted a lefty power bat for LF and signed Jason Kubel. They also dealt for Trevor Cahill and lefty reliever Craig Breslow to fill more needs. Here is a look at the new faces for 2012:

In the field: The Diamondbacks wanted a power stick for LF and they signed Jason Kubel for that role. He has bad knees and he’s not much of a defensive player, but he has a sweet stroke from the left side to help balance the D-Backs’ lineup. Lefty swinging Mike Jacobs will provide insurance in case Lyle Overbay falters in 2012.

On the mound: The Diamondbacks wanted another solid, young starting pitcher for 2012, so they dealt for Trevor Cahill. They also filled another huge hole in the trade that brought Cahill to the D-Backs as lefty reliever Craig Breslow was part of the deal. Breslow is a pretty nasty lefty and the D-Backs have not had one of them in a long, long time. Righty reliever Takashi Saito will give the D-Backs another solid reliever to pitch in the 7th inning this year. Righty relievers Jensen Lewis and Jonathan Albaladejo will also have shots to make the pen this spring.

Overall: Bringing in Kubel, Cahill, Breslow and Saito will prove to be a stroke of genius for the D-Backs. They are going to be a lot better than they were in 2011, and that should strike fear in the rest of the National League.
