Michael Wacha still hasn't been cleared to throw, but he could begin doing so in two weeks.

The St. Louis Cardinals right-hander has a stress reaction in his right scapula, which has healed to the point that he will "ramp up" his pre-throwing program beginning Tuesday.

Wacha underwent both an MRI and CT scan Monday and the results were encouraging.

"This is positive," said John Mozeliak. "This still could put him (pitching for the Cardinals) in early September."
