Cardinals receive positive news on Wacha's MRI

The Cardinals reportedly received good news about young right-hander Michael Wacha on Monday, with the St. Louis Post-Dispatch reporting that an MRI and CT scan on his right shoulder showed encouraging results.

The hope is now that Wacha can begin a throwing program in two weeks, according to the Post-Dispatch.

"This is positive," Cardinals general manager John Mozeliak told Hummel. "This still could put him [pitching for St. Louis] in early September."

Wacha, 23, is 5-5 this season with a 2.79 ERA, but he has not appeared in a game since June 17 -- a six-inning start against the Mets.
