O'Flaherty was activated from the 15-day DL on Saturday, Mark Bowman of MLB.com reports.

EDGE Analysis

O'Flaherty pitched well during his rehab assignment, surrendering only one earned run over six innings while punching out eight batters. The 31-year-old will look to keep it up as he's largely disappointed this season in the majors, compiling a 6.52 ERA and 1.55 WHIP over 27 appearances. Arodys Vizcaino is expected to be sent down to make room for O'Flaherty on the roster.
