I'd appreciate it if the Hall of Fame looked beyond the Negro Leagues Baseball Museum to get their material. Therefore I'll offer three black baseball players, some of whom played in the Negro Leagues briefly, but they spent the majority of their careers in semi-pro baseball on integrated and segregated teams along the West Coast:

Carlisle Perry; High School teammate of the Meusel brothers in LA, California Winter League regular, Negro Leagues (1923-25), manager of the Los Angeles White Sox 1919-29, owner of the LA White Sox of the short-lived West Coast Negro League (1946).

Ernie Tanner; Proclaimed to be "the greatest athlete ever produced in Washington State" Tanner was a four star athlete, but was most known for his early integration of Tacoma baseball, and his work as a longshoreman representative. The Ernest Tanner Cultural Studies Building on the UW branch campus in Tacoma is the former longshoreman's labor hall. His son, Jack Tanner, was also the first African American federal judge West of the Mississippi. Never played in the Negro Leagues though played for the Chicago American Giants when they visited Tacoma.

Jimmy Claxton; Claxton was among the first African Americans depicted on an American baseball card. The first to integrate semi-pro and minor league teams in Washington, Oregon, California, and Nevada prior to World War 2. He managed white semi-pro teams in Washington and Nevada (1926-1938). His stats were impressive: 138 wins, 77 losses, .350 lifetime batting average, 23 strikeouts in a single game (twice), one no-hitter in an integrated semi-pro game (June 23, 1924, he was the only black man on the field). One brief barnstorm through the Negro Leagues 1932 after a significant arm injury the previous season.

Honorable mention, Isaac "Ike" Ward; A former member of the 25th infantry buffalo soldiers, Ward was perhaps the first African American to manage a white semi-pro team in the history of our national pastime when he managed the Colville Indians (1913-15).

A couple other worthy candidates not from the West; John Donaldson, and Subby Byas (Byas once received more votes for the All-Star game than Josh Gibson at the same position).
