This is a link to my work over at ACB on what's wrong with Alfonso Soriano... or, more accurately, what was wrong with Soriano. The short answer is his power has declined steadily over the last few years and he's lost some plate coverage. The good news is that it looks like he may have made adjustments in July that have the potential to bring him back to previous production levels. The sample sizes are small on this so only time will tell whether he does become the monster at the plate we know he's been or if this is just a temporary respite from the ills of age-induced regression.
I'll be in and out all day as I have other (real) work to do. But if you have questions feel free to leave them here or at ACB and I'll be happy to answer them at some point.
