Now that Andrew McCutchen is in San Francisco, the Pirates could use a little more outfield depth. Brentz might be able to provide that, albeit as more of a right-handed half of a platoon in left field (or as a bat coming off the bench).

There was simply no room at the inn for Brentz in Boston, especially following the acquisition of DH J.D. Martinez. With Andrew Benintendi, Jackie Bradley Jr. and Mookie Betts seemingly entrenched in the outfield, Brentz was expendable.

Brentz could be a fantasy dark horse if he manages to earn consistent at-bats against left-handed pitching this season. That said, he is more of a long shot than a sure thing at this point.
