Worth noting

• Opening Day starter Brett Anderson, who returned from the disabled list Wednesday after missing four months with a stress fracture in his right foot, is available to pitch out of the bullpen if needed Saturday, manager Bob Melvin said. The skipper added that Anderson will definitely be available in Sunday's series finale against the Rays.

• With the calendar turning to September on Sunday, Melvin said he expects three players to join the A's expanded roster, though he didn't mention any names. On Tuesday, even more should be bumped up to the big league club as the Minor League seasons end.
