Using data from an official most valuable player award in professional sport, we test for the presence of discrimination by match officials (umpires), who are responsible for ranking the top three players within each match. These umpires are found to award significantly more votes to (and have a higher probability of voting for) players identified as (Australian) Indigenous, after controlling for within-match production. The result offers further evidence on racial discrimination, and runs counter to numerous analogous studies both in sport, as well as in labour and other socio-economic outcomes in general.
