In early 1945, while Robinson was at Sam Huston College, the Kansas City Monarchs sent him a written offer to play professional baseball in the Negro leagues. Robinson accepted a contract for $400 per month. Although he played well for the Monarchs, Robinson was frustrated with the experience. He had grown used to a structured playing environment in college, and the Negro leagues' disorganization and embrace of gambling interests appalled him. The hectic travel schedule also placed a burden on his relationship with Isum, with whom he could now communicate only by letter. In all, Robinson played 47 games at shortstop for the Monarchs, hitting .387 with five home runs, and registering 13 stolen bases. He also appeared in the 1945 East–West All-Star Game, going hitless in five at-bats.
