Yes, there is some truth to the accusation that I resented being bypassed for Groat in 1960. He had a good season but the records will show I contributed a lot more to winning the pennant. I think, too, that a lot of the writers were moved by their racial feelings. An MVP endorsement looks good in the record of a potential manager, and it'll be a long time before we have a colored manager; longer still before there will be a colored Puerto Rican manager. Anyway, it wasn't my 'imagination' hurting me when I complained, it really was my neck. [...] And the doctor says the wrenching of my neck was caused by some unconscious adjustment I had been trying to make because of my back.
