Steve Mann is Director of Player Evaluation at Hendricks Sports. He first joined the major league ranks when he was employed by the Houston Astros in 1979 and 1980 as a statistical analyst. His principal roles were to evaluate the performances of all major league players, to measure the effects of the Astrodome on Houston's hitters and pitchers, and to make projections as to how free agents of potential interest to the club would perform in the club's pitcher-friendly stadium.

In 1980 and 1981, Steve spearheaded the construction of a play-by-play computer system for the Oakland Athletics. Four years later, he designed and directed the development of a more comprehensive software system for the Atlanta Braves and the Philadelphia Phillies.

After successfully working for club management in the salary arbitration arena with Tal Smith Enterprises from 1982 through 1986, Steve joined Hendricks Sports Management in representing players in 1988. He has been with the Hendricks ever since. In his 22 years as an arbitration advocate, he has played a substantial role in the design and delivery of 55 arbitration cases. He also assisted in the preparation and presentation of 74 damage claims and more than 20 appeals in the collusion damage claims process.

In 1989, Steve wrote The Baseball Superstats. Published by McGraw-Hill, the book is a technical guide to analyzing team and individual performance at the major league level. From 1991 through 1997, Steve wrote seven fantasy baseball annuals, the last six of which were published by Harper-Collins. Throughout the 1980s and 1990s, he made numerous radio and TV appearances on sports-talk shows. Steve also authored an essay on the history of baseball's labor-management relations that appeared in the first two editions of Total Baseball, the game's official encyclopedia.

Steve Mann earned a doctoral degree in educational philosophy at Temple University (1980) and served as an assistant director of undergraduate admissions at the University of Pennsylvania (1970-72).

Steve earned a bachelor of arts degree in international relations at the University of Pennsylvania in 1968, where he also played freshman soccer and freshman and varsity baseball. He then served in the United States Army as a motion picture photographer in 1968 and 1969.

Steve and his wife Arlene have a daughter, Abbey, who is a college student. Since retiring in 1997 from Men's Senior League Baseball for players aged thirty or over, Steve has been an avid golfer.
