"Tony and Sandy will observe our club, scout and have input on trades and free agent signings," Minaya said. "In short, they will play a key role in helping us implement our plan."
Johnson, 64, had been employed by the Arizona Diamondbacks in a similar role to the one he'll assume with the Mets. A former boss of Minaya's when the pair were with the Texas Rangers in the mid-1980s, Johnson starts with New York on Nov. 13.
"I've pretty much done everything there is to do in baseball, and I'm here to do whatever Omar wants me to do," Johnson said.
Bernazard, 47, a former major league infielder with the Montreal Expos, Chicago White Sox, Cleveland Indians and Detroit Tigers, had been working with the Major League Baseball Player's Association as a player development liaison. He will join the Mets on Dec. 1.
"Tony Bernazard brings a wealth of knowledge to our organization," Minaya said. "He has experience as a player and his time in the union gives him a unique pulse on what today's players are thinking."
