Sig Mejdal ( /ˈmaɪdəl/ MY-dəl; born December 31, 1965) is the assistant general manager for the Baltimore Orioles of Major League Baseball.
Sig Mejdal grew up in San Jose, California. His mother was a nurse and his father was a career army officer. In his youth, Mejdal played little league baseball for six years. [1]: 43 He was a fan of the 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 Houston Astros, where he supported recruitment decisions based on physical tests and historical player performance. [2] [7] [19] Hiring Mejdal to apply an analytics-based decision tree on their player choices was part of the effort to revitalize the team and address performance issues in prior seasons. [4] He helped the team create the STOUT system, named after the combination of "stat" and "scout," for making player choices. [20] The system was criticized for de-humanizing players, but after trading off some players and making new recruits, the Astro's 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]
