Fans of baseball literature should be in for a treat this spring, as two highly-anticipated books about pitching will be released. One is a collaboration between Rob Neyer and his former employer, Bill James, “The Neyer/James Guide to Pitchers.” The second title is the debut effort by Baseball Prospectus’ injury-guru, Will Carroll. Carroll recently handed in the manuscript for “Saving the Pitcher.” While he’s experiencing some trepidation over how the book will be received, if it is anything like his “Under the Knife” column, it should be insightful, engaging, and above all, educational.
