First, the book comment.
Indeed, the Giants did send him to Triple-A, and he had a fine season, hitting .333/.365/.560 with 31 doubles and 16 homers for Triple-A Fresno. In 24 games for the Giants, he's hit .343/.366/.478. Giants officials are very happy with his performance, and he should get a shot at an outfield job next year.
The question I have is this. Schierholtz doesn't draw many walks, just 17 this year in Triple-A. But he doesn't strike out that much, either, just 58 times in 411 at-bats. His strikeout rate has dropped dramatically compared to 2005, and this is a very positive sign.
As I wrote in the book, the low walk rate makes his OBP highly-dependent on his batting average. Can he hit .300+ in the majors in a full season of play? If he drops much below .285 his on-base percentage will become a problem. . .although if he hits for enough power that might not be a huge issue.
A possible comparison: Garrett Anderson? What do you guys think of Schierholtz?
