The IBAs continue to be maintained by Baseball Prospectus, and for the fourth year, the Greg Spira Baseball Research Award -- for best published original research -- will be bestowed upon someone carrying on the torch of creatively looking at the game ignited by Spira.
Nominations of a story, research paper or book containing original analysis or research of baseball can be made at www.spiraaward.org through 11:59 p.m. ET on Mar. 6. Self-nominations will be accepted.
Winners will be announced on April 27, and will receive cash prizes of $1,000 for the winner and $200 and $100 for second and third place, respectively.
Last year's winner, Lewis Pollis, was recently hired by the Phillies as an analyst in the club's research development department. Pollis, as a Brown University senior, was honored for his economics thesis concerning underpayment of general managers for the value produced to their organizations.
