Book excerpt: When Pedro Martinez won his first Cy Young Award with the Boston Red Sox in 1999 many people in the baseball world claimed it to be one of, if not, the greatest pitching achievement of all-time. Though a remarkable campaign it hardly ranks as the greatest ever. This book lists in order the top 150 pitching performances for a single season between the years 1900-1999. Based on the grading system developed for this book Pedro’s season ranks as the 45th best season for a pitcher. Who is the greatest pitcher in the history of baseball? Is it Walter Johnson or Christy Mathewson? Some may argue for Roger Clemens or Nolan Ryan. The debate as to the best ever will continue but the chapter comparing pitchers of today and yesteryear will offer some new insights. This book will truly interest the baseball enthusiast because it offers clear and interesting data. Plus the measuring stick used for the rankings is not based on opinion, potential or favoritism but rather on fair and unbiased criteria. Eighty-seven pitchers (biographies included), from the famous to the one season wonders, make up the list of the greatest 150 pitching seasons. Included as well are brief summaries of an additional 130 pitchers.
