The Hall of Famer was named manager last February and led the Expos to a surprising second-place finish in the National League East with an 83-79 record, their first winning season since 1996. He finished third in the voting for National League Manager of the Year two weeks ago.
Montreal's financial operations were run by the league last season after Jeffrey Loria sold the club to become the owner of the Florida Marlins.
The Expos have been hurt by poor attendance the last few years and have been rumored to play some home games in Puerto Rico in 2003.
General Manager Omar Minaya told MLB.com, baseball's official website, that he was most impressed by Robinson's "ability to adapt to the game," despite not having managed in more than a decade. Minaya said that the game now is filled with much younger and more culturally diverse players.
Robinson, 67, a member of the elite 500 home run club, became baseball's first black manager when he was hired by the Cleveland Indians in 1975. He also managed the San Francisco Giants and Baltimore Orioles, winning AL Manager of the Year in 1989. He hadn't managed since 1991, and served at his post with Major League Baseball for three years.
Robinson has a career record of 763-830.
