The designation given to any incredibly overpaid baseball player who, in the middle of the contract, suddenly cannot hit over .150. Named for Chris Davis, Baltimore Orioles first baseman, who signed a $161 million contract over seven years. See Mendoza Line.
"Wow, that guy can really hit! We gotta sign him."

"Dude, that guy has more holes in his swing than a zebra has stripes. Two years from now he'll be struggling to reach the Davis Line."
