O'Flaherty (shoulder) was reinstated from the 15-day disabled list Tuesday. Having completed his brief rehab assignment, O'Flaherty will join Fernando Abad as the only healthy lefties in Oakland's bullpen. That could lead to the occasional save opportunity, but O'Flaherty will probably be a better source of holds. While he's thrown just 45 innings since the beginning of 2013, the veteran lefty has mostly remained effective when healthy, with April of this season being the exception.
