"Both went today, both threw well," A's manager Bob Geren said before Wednesday's Bay Bridge Series finale against the San Francisco Giants. "Looking good. No worries there. Looking good. ... Following the schedule, and they'll keep going till they're ready."
Bailey is recovering from a strained right forearm, Harden a strained right lat. Both will start the season on the disabled list.
On Tuesday, Harden threw off a mound for the first time in six weeks, while Bailey made 30 throws from 80 feet. Both are expected to throw again Thursday, when the A's hold their final workout before Friday's season opener in Oakland against Seattle, Geren said. He said he did not have specifics of what each pitcher did on Wednesday.
