Ziegler (knee) is expected to be ready for Opening Day, MLB.com reports.Ziegler recently said that he should be available by Opening Day or shortly thereafter, even though he isn't yet ready to throw off a mound. He's expected to work in the seventh or eighth inning, setting up for the shaky Addison Reed. In the event Reed falters, Ziegler would likely be among the leading candidates for ninth-inning work, despite his consistent lack of strikeouts.
