Matzek (shoulder) had his rehab assignment transferred to Triple-A Gwinnett on Wednesday.

EDGE Analysis

Matzek began his rehab stint at Single-A Augusta on Monday but didn't make any appearances, and he'll progress to the Triple-A level several days later. While the southpaw seems to be closing in on a return, it's not yet clear which day he'll be able to rejoin the major-league club.
