Giants activated LHP Barry Zito from the 15-day disabled list. Zito has been out since mid-April with a mid-foot sprain, but he's healthy now and looked terrific during his four rehab starts, posting a 2.20 ERA, 0.77 WHIP and 25/7 K/BB ratio over 28 2/3 innings. He's taking Jonathan Sanchez's spot in the rotation, with his first start back coming during Tuesday's doubleheader.
