A resolution declaring today Jackie Robinson Day in Los Angeles is expected to be approved during a morning meeting of the Los Angeles City Council.
If passed, the announcement will come four days before the 65th anniversary of Robinson breaking baseball's racial barrier.
On April 15, 1947, Robinson -- who was raised in Pasadena and attended Muir High School -- made his major league debut.
He went hitless in four at-bats, but scored to be what ended up being the winning run in the Brooklyn Dodgers' 5-3 victory over the Boston Braves. 25,623 people at Ebbets Field witnessed history.
Robinson played his entire major league career with Brooklyn, helping lead the Dodgers to six National League championships during his 10 seasons, and, in 1955, their only World Series championship.
Robinson's integration into Major League Baseball is credited with helping change Americans' attitudes toward African-Americans and being a catalyst for later civil rights advances.
Set to attend today's meeting are former LA Dodgers Maury Wills and Tommy Davis, members of honoree's family and officials of the Jackie Robinson Foundation -- an organization providing mentoring, career counseling, and scholarships to academically gifted minority students.
Major League Baseball is preparing to commemorate Jackie Robinson Day at Dodger Stadium during Sunday's game against the San Diego Padres.
Robinson, a graduate of UCLA, wore number 42. That number has been retired from all of major league baseball. Only Yankee pitcher Mariano Rivera still sports the number as he was wearing it before it was retired. Nowadays on MLB's Jackie Robinson Day all players wear the number out of tribute to the star.
