The PIrates have designated reliever Vin Mazzaro for assignment, reports Travis Sawchik of the PIttsburgh Tribune (via Twitter). A 40-man roster spot was needed for first baseman Travis Ishikawa.
Mazzaro lost out on a spot in a deep Bucs bullpen despite posting a 2.81 ERA in 71 2/3 innings last year. It appears that fellow out-of-options relievers Bryan Morris, Stolmy Pimentel, and Jeanmar Gomez will fill out the back of the Pittsburgh relief corps.
