Cubs' Miles Mastrobuoni: Loses 40-man spot

The Cubs designated Mastrobuoni for assignment Thursday, Andy Martinez of Marquee Sports Network reports.

The 29-year-old will end up as the Cubs' roster casualty following the acquisition of Matt Festa from Texas on Thursday. Mastrobuoni has slashed just .219/.279/.263 across 272 career plate appearances in the majors, and his .634 OPS at Triple-A Iowa last season could cause him to pass through waivers unclaimed.
