News: Mazzaro will be recalled from Triple-A New Orleans on Saturday, MLB.com's Joe Frisaro reports.
Impact: He has long been transferred to being a reliever, and a fringy one at that. The Marlins placed two starting pitchers on the DL Friday, so once their rotation replacements are called up Mazzaro will likely be sent back to Triple-A.

News: Mazzaro was reassigned to minor league camp Tuesday, Joe Frisaro of MLB.com reports.
Impact: Despite posting solid numbers with the Pirates in 2013, Mazzaro spent most of last season at the Triple-A level. He's never had much luck piling up strikeouts, and he owns a career ERA of 4.69.
