Cardinals starting pitcher Adam Wainwright, who will be examined Thursday in St. Louis for lower abdominal soreness, said Wednesday he hurt himself while replacing a 45-pound weight during a workout session, per the St. Louis Post-Dispatch.
"It was a very minor deal," Wainwright said. "I did it at the beginning of my workout. I felt a little twinge and didn't even think anything of it and finished my workout another 45 minutes in there.
"I don't think it's very serious at all. (Doctors) are probably not going to see much of anything at all but I don't know that, so I don't want to be answering 100 questions about it without really knowing what's going on."
Wainwright called the exam "strictly precautionary."
"I could go out there and throw a bullpen perfectly fine right now," he said. "It does not hurt to throw at all. The only time it hurts when I'm seemingly running. Maybe, I just pitch this year and don't anybody hit the ball.
"That's what's so frustrating about it. I'm walking around and doing all these things. But, as the symptoms have gone down, it's gotten better and better. I don't foresee this being a problem but I just don't know. It's kind of in that weird area down there."
