The reports of Pujols' inability to straighten his right arm fully are disconcerting, to say the least.
In lieu of surgery, Pujols has also mentioned the possibility of simply scaling back his workload whenever the elbow acts up. It seems the January 10 signing
of Josh Phelps was to prepare for precisely that scenario. As Sp_Da_Man said, Pujols' ADP could drop significantly, depending how the major sites report this.
I agree with others that a midseason shutdown depends almost entirely on the standings.
