Sorrento should be at home in this dome. When predicting a players future, his age is very important. Players tend to improve until they are 27 years old after which they decline. The ability to hit home runs and take walks erodes slower than other skills such as base stealing and hitting for average. I don't factor in age when predicting pitchers.
Young pitchers suffer as much as older pitchers from injury and ineffectiveness.
Yearly Factors Offensive levels vary from year to year and from decade to decade. This fact must be recognized when analysing baseball statistics. Obviously Sosa's and McGwire's home run totals must be adjusted somewhat when comparing them to the home runs hit in eras when runs were not as common. Pitcher's ERAs are also effected. In 1992 an ERA of 4.25 would be unacceptable.
