This is not a temporary problem for Bagwell - but one that has gotten worse over the years and likely will continue to do so. They were speculating on the broadcast yesterday that he may need shoulder replacement after his playing days are over just to have a semi-normal life.
That said, I am curious as to why Berkman, and not Lamb, was at 1B this weekend. They must feel it is easier on his knee. But Lamb looked lost in the OF and I thought he had played 1B last year.
So, as Bagwell is still allegedly a week away from his next cortisone shot, and as Berkman is just back, he may very well get 3 appearances there if Bagwell just can't go. Personally, I think Bagwell toughs it out for most of the week, gets his shot and this issue doesn't come up again until next month - at which time Berkman would stay at OF. So, to answer the original question, my guess is "no" - not because of Bagwell, but because I think Lamb/Vizcaino will get the majority of starts/PT at 1B if Bagwell can't go once Berkman feels "normal" in the OF again.
