Eric O'Flaherty (elbow) could be activated from the disabled list during the Athletics' next homestand, which begins on July 3. Working his way back from Tommy John surgery, O'Flaherty has posted a 4.32 ERA with six strikeouts over 8 1/3 innings during his rehab assignment. The left-hander could prove to be a big part of the A's bullpen if he has regained his pre-surgery stuff.
