Biography

Sig Mejdal grew up in

Oakland A's and a member of the Society for American Baseball Research.[2] According to UC Davis magazine, Sig Mejdal was "fascinated with the stats on the backs of baseball cards."[3] Mejdal graduated from University of California, Davis with bachelor's degrees in mechanical engineering and aeronautical engineering. He later earned master's degrees in operations research and cognitive psychology[4] from San Jose State University.[5] While attending college in the late 1980s, he worked as a blackjack dealer at High Sierra in Lake Tahoe.[4]

After graduating from UC Davis in 1989,[3] Mejdal worked for Lockheed Martin's satellite operations unit at the Onizuka Air Force Station.[1]: 113 [6] Mejdal's interest in baseball was recreational until 2003, when Moneyball inspired him to consider pursuing a career in sabermetrics.[3][7] He attended the Winter Meetings in search for a job in baseball,[8] but ended up working for NASA as a biomathematician in the Fatigue Countermeasures Group.[1]: 23  Mejdal studied sleep patterns of astronauts on the International Space Station[9] in order to optimize their sleep schedules.[8][10]

While working for NASA, Mejdal had a side job as the chief quantitative analyst for Sam Walker's fantasy baseball team Streetwalkers Baseball Club,[10][11] which was participating in the Tout Wars competition's "Battle of the Experts."[10] The fantasy team would later become the subject of Walker's book: Fantasyland: A Sportswriter's Obsessive Bid to Win the World's Most Ruthless Fantasy Baseball.[9]

In 2005, Sig Mejdal was recruited to do sabermetrics for the St. Louis Cardinals' new analytics department.[12] He took 22 months of data from college baseball games and ran it through an algorithm to determine the likely performance and stats baseball players would achieve.[13] According to Sports Illustrated, "[o]ver the next seven seasons the Cardinals would draft more players who became big leaguers than any other organization."[4] He was promoted to senior quantitative analyst in 2008[14] and director of amateur draft analysis in January 2011.[15][16] Mejdal created a formula to predict the risk of injury to baseball players[17] and contributed a section on injury probability to The Bill James Handbook.[18]

In 2012, Mejdal became the Director of Decision Sciences for the

farm system became ranked among the best in baseball.[4] The Astros also used analytics to persuade players that were uncomfortable with non-traditional positions on the field to embrace shifts, which the team now uses very heavily.[4][21]

In 2015, Mejdal was one of the team's advisers whose login credentials were believed to have been used to hack into the team's database.[22]

When Mike Elias was hired from the Astros as general manager of the Baltimore Orioles, Elias hired Mejdal as his assistant general manager.[23]
