Lance Berkman, who was pulled in the middle of the Cardinals' 3-1 win over the Astros Tuesday, said he tweaked his balky right shoulder during his second at bat of the game.
After the contest Berkman said he planned to get an MRI today but that he didn't expect any structural damage to be revealed. He told Fox Sports Midwest that the reason for the test is to try to determine exactly where the discomfort is coming from so he can get a cortisone shot to lubricate the area and numb the pain.
Typically, after getting the shot, players must rest two or three days before they can resume their normal duties.
Let's hope Berkman is correct that this isn't a major issue. The Cardinals sure can't afford to subtract any offense from their line-up as they get ready for a rigorous part of their schedule against NL Central Division foes.
