Cardinals prospect Shelby Miller has been cleared to throw today on flat ground and he said he's been told to take today as if he's getting ready to throw off the mound in the near future.

Miller was pulled from the program Wednesday because of lingering tightness in his right shoulder.

The starter was given treatment that including anti-inflammatory medication and vigorous stretching of the joint. He said the soreness came after his first appearance against hitters this spring. Cleared to play catch today -- on flat ground, about 120 feet, normal stuff -- Miller could then return to the mound for a bullpen session or live batting practice as early as Friday.

"I feel 100 percent," he said. "All good."
