PEORIA, Ariz. -- The D-backs remain hopeful that closer Addison Reed (shoulder) will be ready in time for Opening Day, and while it is less certain that Brad Ziegler (knee) will be ready, there is still a chance for him.
If neither pitcher is ready, the D-backs could turn to right-hander Evan Marshall, who was impressive as a rookie last season.
"He could be a candidate for that if Zieg and Addison aren't ready for Opening Day," D-backs manager Chip Hale said of the closer's role. "If we need somebody, he could always fill in."
Marshall, 24, has closed games in the Minors, saving 16 games for Double-A Mobile in 2012.
For the D-backs in 2014, Marshall had a 2.74 ERA in 57 appearances.
