Wikipedia:Articles for deletion/Bad call
Imagine?  Per , the nominator is supposed to look.  Making assumptions or using guesswork is how bad calls are made.  When I look, I find no shortage of sources discussing the concept in the context of baseball and tennis.  For example, see ''https://books.google.co.uk/books?id=Gyd0dYw0GIMC Major League Umpires' Performance''; ''https://books.google.co.uk/books?id=foLZAAAAMAAJ Call 'Em Right''; ''https://books.google.co.uk/books?id=0lSi_eCQvNwC Scorecasting''; ''https://books.google.co.uk/books?id=YG1vpwAACAAJ Nobody's Perfect''.  The latter is an entire book about how a bad call cost a perfect game
