Wandy Rodriguez (knee) is slated to make a rehab start around the middle of next week. Rodriguez has been cleared of any structural damage in his knee and will throw another bullpen session Sunday. He could just make the one rehab start before rejoining the Pirates' rotation. "In the MRI, he said I can pitch like that. [The doctors] took blood out and put in cortisone," said Rodriguez. "Maybe later, when I retire, I'll need surgery on my knee. Right now, it can stay like that."
