Director of Decision Sciences

Sig Mejdal was named the director of decision sciences for the Houston Astros on January 3, 2012. In his role, Sig helps the baseball operations department evaluate players by reading and extracting various forms of data from scouting reports, medical reports, minor league statistics and other information.

Prior to joining the Astros, Sig worked for the St. Louis Cardinals from 2005-11, most recently as director of amateur draft analytics. During his time with St. Louis, Sig was involved with modeling, analysis, and data-driven decision making throughout all levels of the organization. He was a key contributor in the draft decision processes that led to the selection of more Major League players than any other organization during that time frame.
