D-backs need to trim bullpen before U.S. opener

D-backs need to trim bullpen before U.S. opener

SYDNEY -- The D-backs have some tough decisions to make with regards to their bullpen next week.

For the Opening Series with the Dodgers, the D-backs were able to carry 10 relievers, but they will have to cut down to seven for the March 31 stateside opener with the Giants.

If Randall Delgado claims the injured Patrick Corbin's spot in the rotation, that would leave nine relievers, and it appears that Bo Schultz will head to Triple-A after the Australia trip.

Addison Reed, J.J. Putz, David Hernandez, Brad Ziegler, Josh Collmenter and Oliver Perez all but certainly have spots locked up, leaving a battle between lefty Joe Thatcher and righty Will Harris for the final spot.

Harris has pitched well this spring and did a nice job for the team last season.

Thatcher, meanwhile, struggled early in spring, but has pitched better of late.

One thing working in Thatcher's favor is that he is out of Minor League options, while Harris is not. That means the D-backs could option Harris down to start the season, and he could provide insurance should any of the other relievers falter or get injured.
