The Arizona Diamondbacks officially announced signing RHP Brad Ziegler to a one-year deal. Ziegler was acquired from the Oakland Athletics in a trade last summer at the deadline and pitched in 66 games in 2011 and recorded a 2.16 ERA.
Ziegler will join an improved D-backs bullpen that includes J.J. Putz and David Hernandez at the back and middle relievers Takashi Saito and Bryan Shaw with lefty specialist Joe Paterson. The group looks pretty solid although they probably could use another lefty and a long-reliever to replace the loss of Micah Owings.
