Narrative:

Air carrier X, a B-727, was vectored for a north bay visual approach to runway 17L. Small aircraft Y VFR operating 4 north of airport reported the B-727 in sight and requested a left 360. Controller approved the request. The B-727 pilot later advised that had it not been for a TCASII RA he would have hit the cessna. The aircraft passed 300 ft.
