The Washington Nationals demoted All-Star shortstop CJ Abrams to the minor leagues after he stayed out all night at a Chicago-area casino, leaving only hours before a Friday day game against the Chicago Cubs, sources told ESPN's Jesse Rogers.

Abrams, 23, led off for the Nationals and went 0-for-3 with a walk and strikeout in Friday's game, which started at 1 p.m. CT.
