Jackie Robinson's widow doesn't believe Major League Baseball has fully honored her husband's legacy.

"There is a lot more that needs to be done and that can be done in terms of the hiring, the promotion" of minorities in the sport, Rachel Robinson said.

Robinson took part in a question-and-answer session at the Television Critics Association winter meeting and discussed "Jackie Robinson," a two-part PBS documentary airing in April.

"We're talking about very few [black] coaches, very few managers ... so there's room for real progress, where people can come into the sport and feel they're going to be respected and given opportunities," Rachel Robinson said.

The ballplayer, who broke the sport's color barrier when he started for the Brooklyn Dodgers in 1947, died in 1972 at age 53.
