Wilson and other team officials could not be reached for comment on Thursday.
Wilson had served as the organization's scouting director since Oct. 21, 2010 and has been with the Angels since 2003. Prior to being hired as a national crosschecker, he had spent 11 years with the Milwaukee Brewers organization.
Since replacing Eddie Bane as the scouting director, only two players Wilson has drafted -- first baseman C.J. Cron and catcher Jett Bandy -- have a positive Wins Above Replacement according to baseball-reference. Both Cron and Bandy were selected in 2011, Wilson's first draft as the scouting director.
The Angels' farm system is widely regarded as one of the lowest ranked in baseball, as they are one of two organizations without a single player on the MLB Pipeline list of the top 100 prospects in baseball.
Wilson's resources as scouting director were at times limited, as the signings of Albert Pujols and Josh Hamilton took away the team's first-round picks in both 2012 and 2013. He dealt with changes in the front office, as he served at the role during the tenures of Tony Reagins, Jerry Dipoto and current general manager Billy Eppler.
The different general managers have led to contrasting approaches to the Draft, as Dipoto's emphasis on college players with high floors and low ceilings went out the window for the 2016 Draft. Wilson said following the Draft that Eppler's emphasis was on putting high-potential guys in the Angels' system, something which had been lacking in recent years.
Some of the prospects that Wilson did have success with have found success with other organizations. Left-hander Sean Newcomb and right-hander Chris Ellis find themselves as the No. 3- and No. 16-ranked prospects in the Braves organization, according to MLB Pipeline. Both were used as pieces this offseason in the deal that acquired shortstop Andrelton Simmons. Right-hander R.J. Alvarez, one of the pieces sent to San Diego in the Huston Street deal, made the Majors last season with Oakland.
