Tom "Circus" Mooney was an African American right handed pitcher on the West Coast for more than a decade. He pitched for quite a few teams, the Salt Lake Occidentals and Los Angeles White Sox of the California Winter League, before he moved to Yakima, Washington in the early 1920's.

He integrated the Yakima Police Department nine in the cities' six team Twilight Commercial League in 1922. The league also had as segregated team, the Yakima Giants, but he did not pitch for them until 1923, and only did so as a consequence of the following incident:

“Tom Mooney, Pitcher on the Police Department’s Team, Is Caught Gambling by Police Chief. Tom Mooney, dark twirler for the police baseball nine, forfeited bond of $25 in police court this morning rather than face his teammates and plead against a charge of gambling…. The fact that the police team’s one and only pitcher was himself in the very act of playing the ‘bones’ was the true tragedy. The police nevertheless plan to play him in their next game, which is against the Colored Giants, a colored team.” 6-29-22, Yakima Daily Republic

Up-and-down the West Coast many examples of pre-Robinson integration can be found in city leagues, industrial leagues, and even minor league baseball. Was the West Coast more progressive towards integration, or was this phenomena not regionally specific, and why? Please discuss, all reasonable opinions welcomed, thank you.
